Implementing MPLS Layer 3 VPNs
Associates the local VPN with a route target. When the route is advertised to other provider edge (PE) routers, the export
route target is sent along with the route as an extended community.
Step 8
exit
Example:
RP/0/RP0/CPU0:router(config-vrf-af)# exit
Exits VRF address family configuration mode and returns the router to VRF configuration mode.
Step 9 exit
Example:
RP/0/RP0/CPU0:router(config-vrf)# exit
Exits VRF configuration mode and returns the router to Global Configuration mode.
Step 10 router bgp autonomous-system-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 120
Enters BGP configuration mode allowing you to configure the BGP routing process.
Step 11 vrf vrf-name
Example:
RP/0/RP0/CPU0:router(config-bgp)# vrf vrf_1
Configures a VRF instance and enters VRF configuration mode for BGP routing.
Step 12 rd { as-number | ip-address | auto }
Example:
RP/0/RP0/CPU0:router(config-bgp-vrf)# rd auto
Automatically assigns a unique route distinguisher (RD) to vrf_1.
Step 13 Use the commit or end command.
