First, we will create the OSPF process actually specifying the VRF as part of this process. In this case, it's 1. Features on page 7 Features VRF name increase from 32 to 64 characters Starting with Release 7. You have to enter a different router ID manually. And now to verify ospf is sharing routes between Newcastle and Manchester. If i configure BGP to redistribute the routes, then the routing table populates fine. R4 int lo0 ip add 4. 1 0 FULL/ - 00:00:31 172. OSPF stubs allow the OSPF routers in an area to use default routes for forwarding packets to Area Border Routers (ABRs), rather than more specific routes. The following output includes the VRF OSPFPrivate. Leaking routes from the local routing table to the global routing table. 255 area 0 PE2(config)#router ospf 2 vrf CUSTOMER PE2(config-router)#network 192. Now to my three different scenarios I previously mentioned to break it down in detail: ALL interfaces of a spoke in a vrf. The inband (default VRF) addresses of the 9Ks don't need to be reachable from the rest of the network - the mgmt0 interfaces will be used to manage the 9Ks. No specific debug or show commands are associated with this feature. A route distinguisher (RD) is a number -- which doesn't actually have any real significance other than to help identify a VPN in a provider's network and allow for overlapping IP space. This article compares some of the NX-OS VRF command syntax with IOS VRF command syntax. The other command, "tunnel vrf MyVRF" is only used if your WAN interface is included in the vrf. Configures the specified OSPF process with the VRF associated with the sham-link interface on PE-2 and enters interface configuration mode. Question 5. Chapter 27 Configuring VRF-lite VRF-lite Configuration Guidelines VRF-lite Configuration Guidelines Consider these points when configuring VRF in your network: † A switch with VRF-lite is shared by multiple customers, and all customers have their own routing tables. OSPF Process ID 100 VRF default. OSPF network type NBMA (Non-Broadcast Multiple Access) uses only unicast communications, so it is the preferred way of OSPF configuration in situations where multicast addressing is not possible or desirable for some reasons. The "router ospf" configuration is applied before the interface configuration that would supply IP addresses for use as router IDs. 40 IfIndex = 2 Run as demand circuit DoNotAge LSA allowed. Supports opaque LSA. "vrf definition" command, how to survive. router ospf 1 vrf Customer-A network 10. To them, they are connecting to the router VOICE and LAN, respectively. The next output does not include the VRF. However, there is a problem. This is a sample configuration of using OSPF with IPsec VPN to set up network redundancy. Configure redistribution between OSPF and BGP on the PE routers, make sure you use the correct VRF. Configure management VRF. In our case, I have configured vrf ALL-VRF in RR and imported all the route-targets 123:1, 123:2 and 123:4.

Client 1 is now communicating with PE1's VRF 1 and Client 2 on VRF 2. If a Layer 3 switch running OSPF in a VRF-lite configuration reports this error, which action can you take to correct the problem? A. The OSPF process ID is the identifying number assigned to the OSPF process. Use the following command to specify the maximum amount of time advertised to an OSPF neighbor router to maintain routes from and forward traffic to a restarting router. 2/32 and vrf as OSPF-VRF and assign it to interface eth2/1 and loopback0. router ospf 1 vrf london network 0. Step 5 Next we start our OSPF configuration , this Lab is completed under vrf just to show the vrf functionality along with OSPF, we can also run OSPF without vrf instance in NXOS like we do in IOS. SW refused configuration. The OSPF dynamic routing protocol is probably the most popular LAN routing protocol today. In addition to the global routing table (VRF0), up to 255 virtual route forwarding (VRF) instances are supported. In this lesson we'll take a look how to configure a MPLS Layer 3 VPN PE-CE scenario. You can configure ECMP or primary/secondary routes by adjusting OSPF path cost. 1/30 R3: set interfaces ge-0/0/2 unit 0 family inet.

Configure a static route for a management VRF instance. 0 log adjacency!Assign VRF instances to Layer 3 interfaces!NOTE: When a VRF instance is assigned to an interface, all IP addresses are deleted, and will trigger cache deletion, route deletion and associated cleanup. router ospf 1 vrf london network 0. Configuration Examples for Multi-VRF CE Multi-VRF CE Configuration Example OSPF is the protocol used in VPN1, VPN2, and the global network. Create a new Loopback on R6 with the address 6. 66 on Vlan67 from FULL to DOWN, Neighbor. For example, here is the output of the command on R1: You can see that R1 has learned about the network 192. As the core ISP is using OSPF process 1 we will use process 2 for the PE-CE configuration. Based on business needs, dual datacenter networks will evolve from an "active/standby" disaster recovery configuration that has an active primary datacenter carrying workloads and a site sitting on standby over to a "active/active" datacenter environment with. We then configure the other VRF (on PE1) to import routes that contain the route target. 3 cost 10 ip route 10. First, we will create the OSPF process actually specifying the VRF as part of this process. Configure BGP AS 1 between Router PE1 and PE2. Also, when in the OSPF configuration context, I can't put the Gigabit 0/0 interface in passive, as it's not part of the LAN router. We will configure two PE-CE routing protocols; BGP and OSPF, in VRF-lite setup and enable support for MPLS label exchange all the way to the CE router. Rack1R2(config-vrf) #rd 1:14 We will now tell the VRF to export and import anything with a tag of 1:14. This permits multiple network paths without the need for multiple switches. You can verify the success of the OSPF multi-VRF configuration by using the show ip ospf [process-id] command to verify that the router is not connected to the VPN backbone. This short video walks through the creation of a VRF, and explains one of the many reasons people use them. Below template used in PE2.

Once the OSPF configuration is done on the client's device, the connections should be established: PE1#sh ip ospf neighbor. Note that when entering OSPF process configuration, we no longer need to append the vrf keyword as it has already been applied. Also, when in the OSPF configuration context, I can’t put the Gigabit 0/0 interface in passive, as it’s not part of the LAN router. Configuring OSPF. 1X configuration examples This chapter provides examples for configuring 802. Upgrade the Layer 3 switch to a model that can support more routes. OSPF network type NBMA (Non-Broadcast Multiple Access) uses only unicast communications, so it is the preferred way of OSPF configuration in situations where multicast addressing is not possible or desirable for some reasons. 16; For the VPN, configure OSPF: Configure area 0 and add the ge0/2 interface to this area: vEdge2(config)# vpn 2 router ospf area 0 interface ge0/2; Configure the interface between the vEdge2 router and its local-site router: vEdge2(config)# vpn 2 interface ge0/2 ip address 172. 0 area 0 R5. As can be seen, "sh ip ospf nei" shows them whether they are in their own VRF's or not, they are still OSPF neighbors, however even after a "clear ip ospf proc" on both R1 and R2 it is still showing 10. However I do not want to use. cl/2z4M8hL - This lesson explains what VRFs are and how to configure VRF Lite on Cisco IOS routers. Each VRF contains its own Address Space, Unicast, and Multicast routing tables that make decisions independent from each other. In this situation, the best practice is to limit RIP network as such and use a newer routing protocol on the rest part of the network, such as OSPF. All interfaces include "vrf forwarding MyVRF". Router2 configuration is the same as Router1, except Router2 also has the DSL interface to configure. And after checking Customer configuration on MHNDSN. This article will show you the way to Configure VRF in Cisco IOS Router and allow the usage of overlapping address. While OSPF can be complex to configure. Getting Started. g both OSPF and EIGRP ). Configures the specified OSPF process with the VRF associated with the sham-link interface on PE-2 and enters interface configuration mode. s1(config-router)#cabability vrf-lite the ospf process goes down and comes back up and we now have the ospf routes 00:36:23: %OSPF-5-ADJCHG: Process 100, Nbr 66. Given that, OSPF will be around for some time. 0!! router ospf 1 vrf customer1. 255 area AREANUMBER Cisco IOS, NX-OS CLI Commands Cisco ACL Configuration Examples. However, there is a problem. Configuring source IP address for a leaked route. Therefore, we will configure the MP-BGP to distribute customers' prefixes. /24 through OSPF. By default a router uses a single global routing table that contains all the directly connected networks and prefixes that it learned through static or dynamic routing protocols. This technology allows multiple routing domains to co-exist within the same device at the same time. We can still route to 33. In other words, when a prefix is exported with a route-target, an extended BGP community is attached to that prefix. Review basic router configuration. 0 area 0 ! router ospf 3 vrf manchester network 10. I have basically 3 networks here: VRF Green, VRF Blue, and the yellow Service Provider backbone network. OSPF VRF to OPSF Global Route leaking Examples from PE to PE ===== PE2 Side template! // Adding the Static routes in the Global for pointing to the VRF BLUE , Vlan 106! ip route 10. SW refused configuration. Figure 13-1 VRF Lite—Sample Network Scenario. Router2(config)# router ospf process-id vrf vrf-name. Configuring static route leaking. Verifying the OSPF Multi-VRF Configuration. Create the VRF and set the route distinguisher (rd). When implementing OSPFv3, which statement describes the configuration of OSPF areas? A. Below template used in PE2. This is where things start to get interesting. 3 ! all the rest of settings remain unchanged. Configuring source IP address for a leaked route. The next output does not include the VRF. Configure OSPF on Juniper: First of all, let's configure IP addresses for all the devices. The network has been configured with OSPF 100 for the client, and OSPF 200 for the ISP backbone and basic reachability has been confirmed within each of those OSPF domains. Learn OSPF configuration commands, OSPF show commands, OSPF network configuration (Process ID, Network ID, Wild card mask and Area number) and OSPF routing in detail. MPLS Inter-AS Option A Diagram 1 - Sample Topology of MPLS Inter-AS Option A with EIGRP and OSPF In the Diagram 1, R1 and R5 are ASBRs that have two subinterface, each belonging to its respective vrf: blue and red. Configuring OSPF interface settings; Configuring OSPF interface authentication; Configuring OSPF virtual link settings; Configuring OSPF authentication on a virtual link; Configuring all OSPF interfaces as passive; Viewing OSPFv2 information; Clearing OSPF statistics on a switch; An example of the OSPFv2 information in the show running-config. The inband (default VRF) addresses of the 9Ks don't need to be reachable from the rest of the network - the mgmt0 interfaces will be used to manage the 9Ks. ip ospf 1 area 0! interface Ethernet0/1 ip vrf forwarding Client2 ip address 172. Overview; Loopback commands. I took my VRF with OSPF configuration and added the EIGRP VRF commands. The OSPF dynamic routing protocol is probably the most popular LAN routing protocol today. The "router ospf" configuration is applied before the interface configuration that would supply IP addresses for use as router IDs. Traffic and routing. I left the outside world static routes in OSPF to show OSPF still works. Each VRF contains its own Address Space, Unicast, and Multicast routing tables that make decisions independent from each other. The following output includes the VRF OSPFPrivate. Cisco IOS Router supports both protocols but the challenge to this implementation is that hosts in RIP network will not be. Since OSPF is also in the blueprint for the CCNP Route exam i decided to go with an OSPF configuration in this lab. Below is the OSPF configuration example on Nexus switches. Create the VRF and set the route distinguisher (rd). Note: All router-id's have been configured relative to their router number. You have to enter a different router ID manually. Question 5. Configures the specified OSPF process with the VRF associated with the sham-link interface on PE-2 and enters interface configuration mode. However, we can break this up into a simpler example with just 3 devices to illustrate the VRF-lite redistribution behavior. 11 wireless networks multicast packets are not always reliably delivered (read. In router configuration mode, the network wildcard area ID combination assigns networks to OSPFv3 areas. Configure the 192. ipv6 ospf bfd all-neighbors. The first lab starts at the beginning and shows basic VRF configuration to separate two customers. switch(config)# ip route 0. Using the show OSPF Command. There's one customer with two sites, AS 1 and AS 5. This command does not affect the actual device configuration. To configure OSPF as a PE-CE routing protocol you need to start a separate OSPF process for each VRF in which you want to run OSPF. Configuring static route leaking. Within the OSPF process configuration mode, the OSPF process ID is defined (using the router-id ospf-process-ID command). 2 redistribute bgp 100 subnets network 0. Virtual Routing and Forwarding (VRF) is a technology that enables the usage of multiple routing table instance in a layer-3 device. The border router connects to a BGP network. 1X configuration examples This chapter provides examples for configuring 802. Supports opaque LSA. This example also shows enabling OSPF on a loopback interface. If you change the OSPF router ID, we need to either reload the IOS or use "clear ip ospf process" command, for OSPF. 5 for sending and receiving Hello packets. The router uses an algorithm based on the OSPF packet, the key, and the key-id to generate a "message digest" that gets appended to the packet. But, we can use route-targets and MP-BGP to share routes between VRF's on different routers. We'll do the same thing for VRF Red so that Red1/Red2 can reach each other. OSPF VRF to OPSF Global Route leaking Examples from PE to PE ===== PE2 Side template! // Adding the Static routes in the Global for pointing to the VRF BLUE , Vlan 106! ip route 10.

Cisco Catalyst 9500 series Configuration Manual. Create OSPF Processes 1. This router has 2 separate OSPF processes, and is lacking MPLS/BGP/VRF configuration. 5in x 14in / 215. 255 ip ospf 2 area 2 int f0/0 ip add 192. VRFs in MPLS is a rabbit hole that goes pretty deep,…so I'll attempt to stick to what's on the exam. 3 Configuring the BGP Route Between PE and CE Refer to the following configuration commands: Command Purpose. device (config)# router ospf vrf blue device (config-ospf-router)# graceful-restart restart-time 120. PE02(config-router)#network 192. Valid values are an integer, in milliseconds, or the keyword 'default'. This permits multiple network paths without the need for multiple switches. ) OSPF version 2 is used for IPv4; OSPF version 3 for IPv6. Easy Virtual Network (EVN) is an IP. R1(config)# router ospf [Process-id] vrf [NAME] Configure RIPv2 and VRF Lite. In the configuration mode, type router ospf to enter global OSPF profile. State of ospf vrf configuration. 2R1 This guide describes how to configure OSPF on Brocade products that run on the Brocade Vyatta Network OS (referred to as a virtual OSPF Configuration. OSPF been configured with just with a very basic config to get the areas up and running. Join me to see how we can configure a network with VRF's, as well as EIGRP, OSPF, and BGP. redistribute bgp 8452. Solved using under every process manual conf router-id process L0 ip address. After : SP#sh ip ospf neighbor &#xOS;PF: Router process 3 is not running, please configure a router-id although i'had used l0 interfaces. Let's start with a basic DMVPN phase 3 configuration: Hub(config)#interface Tunnel0 Hub(config-if)#ip address 172. Next, add the networks you would like to include in this process specifying the OSPF area as well. Note the lack of specific OSPF information within area 0. OSPF can be run with any VPRN, independently of the routing protocols used in other VPRNs, or in the backbone itself. OSPF network type NBMA (Non-Broadcast Multiple Access) uses only unicast communications, so it is the preferred way of OSPF configuration in situations where multicast addressing is not possible or desirable for some reasons. Rack1R2(config-vrf) #rd 1:14 We will now tell the VRF to export and import anything with a tag of 1:14. Understanding OSPF Routing Instances, Example: Configuring Multiple Routing Instances of OSPF. Interfaces IP Addresses. Routers R4 and R5 are configured in OSPF area 0 and connected to an MPLS VPN (named sham-vrf) The design requires that traffic prefers the path across the MPLS VPN (shown by the red line). ip ospf 2 area 0. 1 or lt-0/0/0. Router1 will be the designated router (DR) and router2 will be the backup DR (BDR) due to their priorities. Hello fellow network nerds, I'm in the process of migrating a campus network from EIGRP to OSPF and I'm trying to decide how to organize the OSPF areas in a way that makes sense, and ask you. network 10. Example 6-17 Configuration of OSPF for PE-CE Routing router ospf 100 vrf mjlnet_VPN redistribute bgp 64512 subnets network 172. Now to my three different scenarios I previously mentioned to break it down in detail: ALL interfaces of a spoke in a vrf. Therefore, we will configure the MP-BGP to distribute customers' prefixes. We are trying to ping the 192. 3 Configuring the BGP Route Between PE and CE Refer to the following configuration commands: Command Purpose. However, on Cisco routers, you…. The first command in the configuration is router ospf process_ID vrf vrf_name. vrf - Name of the VRF to apply OSPF configuration to. FEATURE OVERVIEW AND CONFIGURATION GUIDE Introduction In IP-based networks,VRF stands forVirtual Routing and Forwarding. Create VRF Instances 1. How does the OSPF cost work? In this post, I will handle the OSPF cost (OSPF cost and auto-cost reference-bandwidth). OSPF VRF to OPSF Global Route leaking Examples from PE to PE ===== PE2 Side template! // Adding the Static routes in the Global for pointing to the VRF BLUE , Vlan 106! ip route 10. c7200(config)#router ospf 1 vrf OSPF_1 c7200(config-router)#network 0. Notes during CCIE learning and practice. No specific debug or show commands are associated with this feature. Each VRF can be assigned one or more Layer 3 interfaces on a router to be part of the VRF. Question 5. Let's configure OSPF within VRF Blue so that Blue1/Blue2 are able to reach each other. Basic OSPF example. There are 3 routers, all running OSPF v2. Pick Alphanumeric Name 2. Configure redistribution between OSPF and BGP on the PE routers, make sure you use the correct VRF. 0/24 through OSPF. View VRF instance information. It also supports the advertisement of VPN. 1 guest_inet up JunOS ⌗ Junos has the concept of routing instances which are used to setup separate instances of OSPF, ISIS, BGP, etc, as well as static routes. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS). The network has been configured with OSPF 100 for the client, and OSPF 200 for the ISP backbone and basic reachability has been confirmed within each of those OSPF domains. In addition to the global routing table (VRF0), up to 255 virtual route forwarding (VRF) instances are supported. router ospf 1 vrf Customer-A network 10. The following new commands are added to the Command Line Interface (CLI). 3 cost 10 ip route 10. The user can enable OSPF FRR to either automatically calculate a backup next hop, or to designate a backup next hop by using a routing policy. 3 ! all the rest of settings remain unchanged. 44 LSA has the DN bit set from PE2. This output from the show ip ospf process command indicates that the PE router is currently connected to the. As can be seen, “sh ip ospf nei” shows them whether they are in their own VRF’s or not, they are still OSPF neighbors, however even after a “clear ip ospf proc” on both R1 and R2 it is still showing 10. Question 7. Router1 will be the designated router (DR) and router2 will be the backup DR (BDR) due to their priorities. This article will show you the way to Configure VRF in Cisco IOS Router and allow the usage of overlapping address. OS10 Enterprise Edition User Guide Release 10. 5in x 14in / 215. >> keep this same for this vrf at every site. In default vrf I configured ospf, all is working fine: > sh running-config section ospf interface Vlan4093 ip address 10. You'll need to identify OSPF by a process ID. 0 area 0 ! router bgp 1 no synchronization no auto-summary ! address-family ipv4 vrf newcastle redistribute connected redistribute ospf 2 vrf newcastle match internal no synchronization exit-address-family !. Mikrotik Routing Table. By default a router uses a single global routing table that contains all the directly connected networks and prefixes that it learned through static or dynamic routing protocols. 1/8 so that it is unique in the routing table. However, on Cisco routers, you…. Set mls cef maximum-routes in the global configuration. Hi all, OSPF Intra, OI - OSPF Inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2 exit Exit from VRF configuration mode no. 66 on Vlan67 from FULL to DOWN, Neighbor. In our case, I have configured vrf ALL-VRF in RR and imported all the route-targets 123:1, 123:2 and 123:4. OSPF Global in PE1——————-> OSPFGlobal in PE2 AND OSPF VRF in PE2. Route leaking using route targets. In this lab I’m going to go over the config for an MPLS VPN. interface loopback; ip address; ipv6 address; vrf attach. ip ftp vrf.

When implementing OSPFv3, which statement describes the configuration of OSPF areas? A. 00/8 interfaces in that VRF router ospf 1 vrf Customer-B network 10. OSPF checks if the PE router is needed to prevent loops when the PE is performing a mutual redistribution. …IP-VRF-forwarding is an interface sub-command…that binds that interface to a VRF instance. router ospf 7 vrf VPN7 router-id 2. OSPF can scale to the largest LANs but can also start out small. 201 auto-cost reference-bandwidth 40000 passive-interface default no passive-interface Vlan4093 redistribute. nxos_ospf_vrf - Manages a VRF for an OSPF router State of ospf vrf configuration. DC router have two VRF's, therefore, OSPF configuration has two processes one for each VRF. However, this is not enough to exchange information between the two routing protocols. The tutorial below will focus on Routing Redistribution between OSPF and EIGRP and vice-versa. VRF Lite OSPF design - sanity check. When redistributing OSPF into BGP, you have to specify the type of OSPF routes that should be redistributed. The router uses an algorithm based on the OSPF packet, the key, and the key-id to generate a "message digest" that gets appended to the packet. Routers R4 and R5 are configured in OSPF area 0 and connected to an MPLS VPN (named sham-vrf) The design requires that traffic prefers the path across the MPLS VPN (shown by the red line). This output from the show ip ospf process command indicates that the PE router is currently connected to the. The "router ospf" configuration is applied before the interface configuration that would supply IP addresses for use as router IDs. Cisco OSPF Command and Configuration Handbook provides example scenarios that demonstrate the proper use of every OSPF command that can be implemented on a minimum number of routers. MP-BGP is a little different from legacy BGP in that it supports multiple address families (e. 201 auto-cost reference-bandwidth 40000 passive-interface default no passive-interface Vlan4093. The BGP/MPLS VPN configuration will undergo the following milestones:PE-PE relationship configuration with VPN IPv4 address family introduction; PE-CE routing configuration with both BGP and OSPF as. In this lab I’m going to go over the config for an MPLS VPN. This increases functionality by allowing network paths to be segmented without using multiple devices. For more information about the OSPF protocol, refer to the 7750 SR OS Router Configuration Guide. OSPF Router ID is an IPv4 address (32-bit binary number) assigned to each router running the OSPF protocol. 255 area 0! router bgp 100 bgp router-id 3. mcRNC Site Solution with OSPF and VRF Site Solution option applies dynamic routing for distributing the user plane application IP addresses to site routers. Process ID - Defines the OSPF process ID that OSPF will run under. cl/2z4M8hL - This lesson explains what VRFs are and how to configure VRF Lite on Cisco IOS routers. Routers R4 and R5 are configured in OSPF area 0 and connected to an MPLS VPN (named sham-vrf) The design requires that traffic prefers the path across the MPLS VPN (shown by the red line). That's as easy as I can explain it. Previously I introduced FlexVPN IKEv2 via labs, this time is about DMVPN IKEv2. All interfaces include "vrf forwarding MyVRF". By default a router uses a single global routing table that contains all the directly connected networks and prefixes that it learned through static or dynamic routing protocols. ) OSPF version 2 is used for IPv4; OSPF version 3 for IPv6. With VRF-Lite, a router is configured with multiple subinterfaces, one for each VRF. R1(config)# router ospf 1 R1(config-router)# default-information originate R1(config-router)# router ospf 2 R1(config-router)# default-information originate. 5 /32 between its sites using BGP. 17 redistribute bgp 64512 metric 1 subnets route-map bgp-ospf100 network 192. Initial configuration: As an IGP we are using OSPF with maximum paths feature configured: Arista(config)#router ospf 1 Arista(config-router-ospf)#maximum-paths 32 There are two iBGP peers configured via a peer-group “pg1”: Arista(config)#router bgp 65001 Arista(config-router-bgp)#neighbor pg1 maximum-routes 16000 Arista(config-router-bgp)#. Configure the tunnel1 interface on both routers. In the configuration mode, type router ospf to enter global OSPF profile. There are 3 routers, all running OSPF v2. switch(config)# ip route 0. Once the OSPF configuration is done on the client's device, the connections should be established: PE1#sh ip ospf neighbor. ip address 10. Overlay networks provide an obvious benefit of removing the VRF configuration from the core, but require the additional configuration needed for tunnels. 1 ip ospf network point-to-point ip ospf 1 area 0 negotiation auto! interface GigabitEthernet4 no ip address negotiation auto! interface GigabitEthernet5 no ip address negotiation auto! interface GigabitEthernet6 no ip address negotiation. The actual configuration of a VRF is not a difficult task. Requirements: Clients: • All SeaTac, Renton, and Everett clients can access Bellevue and the Internet. MP-BGP is a little different from legacy BGP in that it supports multiple address families (e. Key take-away: NX-OS is pretty. 1/30 R3: set interfaces ge-0/0/2 unit 0 family inet. Mikrotik Routing Table. This is used to logically isolate the virtual routers with each of them having their own routing tables. Hi all, OSPF Intra, OI - OSPF Inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2 exit Exit from VRF configuration mode no. vrf - Name of the VRF to apply OSPF configuration to. 255 area 0 PE2(config)#router ospf 2 vrf CUSTOMER PE2(config-router)#network 192. I left the outside world static routes in OSPF to show OSPF still works. Multi-VRF (VRF-Lite) With OSPF and BGP Multivrf (VRF-Lite) MPLS Multi-VRF provides the extension to configure and maintain more than one instance of a routing and forwarding table within the same CPE router, That means we are hereby extending the vrf to CPE instead of PE to provide better services to customers by using same physical link and. In Cisco IOS router, this feature is available by default. 3 cost 10 ip route 10. 1460 Bytes is the number of bytes available for TCP ‘data’. When using the on-startup option you can set a time in seconds for which the. I will lab it configuring this network topology: The VRF-Lite feature extends VRF capability to a CE router, this means that at CE we can separate routing informations among different customers. Please configure manually or bring up an interface with an. Route Leak between VRFs with Import MAP. router ospf process-id. OSPFv2 maintains multiple instances of the routing protocol to exchange route information among various VRF instances. Router(config-vrf)# ip vrf forwarding vrf-name To check your configuration, you can use ping or traceroute tools under Cisco CLI, but remember that you have to use “vrf vrf-name” parameter: Router# ping vrf vrf-name IP-address Also you can check the virtual routing table: Router# show ip route vrf vrf-name (Note: The RD / RT is a 8-byte (64.
