neighbor activate
Creates a peer entry to the MBGP neighbor table.
Syntax: [no] neighbor {ip-address | peer-group-name} activate
ip-address
IP address of the neighbor added to the MBGP neighbor table.
peer-group-name
Name of a BGP peer group.
Description: MBGP must fully understand the relationships between neighbors.
Use the neighbor ip-address activate command to create a peer entry in the MBGP neighbor table.
Use the neighbor peer-group-name activate command to configure all the members of the named BGP peer group to inherit the attribute configured with this command.
Use the no neighbor activate command to remove an entry from the MBGP neighbor table.
You must enable both ends of the link for MBGP before a route becomes active.
You must first enable the BGP peer or peer-group using the neighbor remote-as command before you can enable the peer or peer-group for MBGP.
Whether an enabled MBGP peer or peer-group is configured for multicast only or both unicast and multicast depends upon IPv4 address family command mode.
If the peer or peer-group is to be configured for both unicast and multicast services, enter the neighbor activate command in multicast IPv4 address family command mode. In multicast mode this command defaults to both unicast and multicast services.
If the peer or peer-group is to be configured for multicast services only, first enter the neighbor activate command in multicast IPv4 address family command mode. Then enter a no neighbor activate command for the same peer or peer-group in unicast IPv4 address family command mode to disable unicast services.
Factory Default: None.
Command Mode: IPv4 address family (unicast | multicast).
Example 1: The following example enables both MBGP multicast and unicast services for peer 10.5.12.106:
router(config)#router bgp 100
router(config-router)#neighbor 10.5.12.106 remote-as 100
router(config-router)#address-family ipv4 multicast
router(config-router-af)#neighbor 10.5.12.106 activate
router(config-router-af)#end
router#
Example 2: The following example enables MBGP multicast capability only for peer 10.5.12.106:
router(config)#router bgp 100
router(config-router)#neighbor 10.5.12.106 remote-as 100
router(config-router)#address-family ipv4 multicast
router(config-router-af)#neighbor 10.5.12.106 activate
router(config-router-af)#exit
router(config-router)#address-family ipv4 unicast
router(config-router-af)#no neighbor 10.5.12.106 activate
router(config-router-af)#end
router#
