Conguring a BGP VRF address family
To perform BGP conguration between two neighbors that must exchange IPv6 or IPv4 VRF information, use the following commands.
Following are the steps to congure BGP VRF address-family between two peers.
• Congure a VRF routing table.
CONFIG mode
ip vrf vrf-name
For more information on VRF conguration, see Virtual Routing and Forwarding (VRF).
• Add the IP address of the neighbor for the specied autonomous system.
CONFIG-VRF mode
ip route-import tag
• Enter the router conguration mode and the AS number.
CONFIG mode
router bgp as-number
• Specify the IPv4 address family conguration.
CONFIG-ROUTER-BGP mode
address-family {ipv4 | ipv6} vrf vrf-name
vrf vrf-name — Species the name of VRF instance associated with the IPv4 or IPv6 address-family conguration.
• Add the IP address of the neighbor in the specied AS to the IPv4 MBGP neighbor table.
CONFIG-ROUTER-BGP-AF mode
neighbor {ip-address | ipv6–address | peer-group-name} remote-as as-number
