Implementing MPLS Layer 3 VPNs
Example:
RP/0/RP0/CPU0:router# configure
Enters Global Configuration mode.
Step 2 router rip
Example:
RP/0/RP0/CPU0:router(config)# router rip
Enters the Routing Information Protocol (RIP) configuration mode allowing you to configure the RIP routing process.
Step 3 vrf vrf-name
Example:
RP/0/RP0/CPU0:router(config-rip)# vrf vrf_1
Configures a VPN routing and forwarding (VRF) instance and enters VRF configuration mode for RIP routing.
Step 4 interface type instance
Example:
RP/0/RP0/CPU0:router(config-rip-vrf)# interface TenGigE 0/3/0/0
Enters VRF interface configuration mode.
Step 5 site-of-origin { as-number : number | ip-address : number }
Example:
RP/0/RP0/CPU0:router(config-rip-vrf-if)# site-of-origin 200:1
Identifies routes that have originated from a site so that the re-advertisement of that prefix back to the source site can be
prevented. Uniquely identifies the site from which a PE router has learned a route.
Step 6 exit
Example:
RP/0/RP0/CPU0:router(config-rip-vrf-if)# exit
Exits VRF interface configuration mode, and returns the router to VRF configuration mode for RIP routing.
Step 7
Do one of the following:
• redistribute bgp as-number [ [ external | internal | local ] [ route-policy name ]
• redistribute connected [ route-policy name ]
• redistribute isis process-id [ level-1 | level-1-2 | level-2 ] [ route-policy name ]
• redistribute eigrp as-number [ route-policy name ]
