Usage
Information
By default, when you create a neighbor/peer group configuration in the Router BGP context, this enables
IPv4/Unicast AFI/SAFI. When you use activate in the new context, the neighbor/peer group enables
for AFI/SAFI. It is possible to activate or de-activate a peer from the IPv4/IPv6 unicast address family.
NOTE: The no neighbor peer ip-address activate command takes precedence over the
no neighbor peer-group-name activate command.
The following tables list the neighbor activation and its expected results for IPv4 and IPv6 address
families:
