Re: address-family ipv4 in BGP

Hello Rupesh,

usage of address families is not limited to IPv4 and ipv6:

Multi protocol BGP allows for:

vpnv4 AF that provides signalling plane for MPLS L3 VPN

ipv4 vrf vrf-name : context for VRF related sessions

ipv4 multicast: to be used in inter-domain multicast to provide a way to satisfy RPF check for sources coming from other BGP AS.

other address families are out there for inter-AS EoMPLS for example.

Using ipv4 address-family directly also for ipv4 unicast only contexts makes more consistent the aspect of the configuration.

Hope to help

Giuseppe
