Usage Guidelines
Usage Scenario
Before performing BGP configurations in an IPv4 address family, you need to run the ipv4-family command in the BGP view to enable the IPv4 address family, and then enter the address family view. By default, BGP uses the IPv4 unicast address family.
Precautions
To disable the IPv4 unicast address family from being the default BGP route, run the undo default ipv4-unicast command.
