Conguring a BGP peer
To congure BGP between two peers, use the following commands.
Following are the steps to congure a BGP peer. The following example conguration demonstrates how the congure a neighbor and IPv4
multicast address family. The default is IPv4 unicast address family.
• Enter the router conguration mode and the AS number.
CONFIG mode
router bgp as-number
• Add the IP address of the neighbor for the specied autonomous system.
CONFIG-ROUTER-BGP mode
neighbor {ip-address | ipv6–address | peer-group-name} remote-as as-number
• Enable the neighbor.
CONFIG-ROUTERBGP mode
neighbor ip-address | ipv6-address | peer-group-name no shutdown
• Specify the IPv4 address family conguration.
CONFIG-ROUTER-BGP mode
address-family ipv4 [multicast | vrf vrf-name]
multicast — Species the IPv4 multicast address family.
vrf vrf-name — Species the name of VRF instance associated with the IPv4 address-family conguration.
• Enable the neighbor to exchange prexes for IPv4 unicast address family.
CONFIG-ROUTER-BGP-AF (Address Family) mode
neighbor {ip-address | ipv6–address | peer-group-name} activate
NOTE
: Neighbors have to be activated using neighbor activate command in the respective address family to
exchange other address prex types such as IPv4 multicast and IPv6 unicast.
