Address families
MP-BGP adds support for Address families and Sub Address families in addition to IPv4 Unicast which was supported by base BGP (RFC 4271). The 10.02 release supports IPv4 Unicast and IPv6 Unicast address families. Use the
address-family {<ipv4> | <ipv6>} unicast
commands to enter the address-family configuration mode and execute address-family specific configurations.
