Usage Guidelines
Use the
address-family
command to enter various address family configuration modes while
configuring BGP routing. When you enter the
address-family
command from neighbor configuration
mode, you enable the neighbor address family and enter the neighbor address family configuration mode.
The prompt changes to
switch(config-router-neighbor-af)#.
You must configure the address families if you are using route redistribution, load balancing, and other
advanced features. IPv4 neighbor sessions support IPv4 unicast and multicast address families.
This command requires the LAN Enterprise Services license.
