BGP address family support for different session types

When the base router has a neighbor identified by an IPv4 address, and therefore the transport of the BGP session uses IPv4 TCP, all MP-BGP address families available in SR OS are supported by that session.

When the base router has a neighbor identified by an IPv6 address, and therefore the transport of the BGP session uses IPv6 TCP, the following MP-BGP address families are supported:

• ipv4

• ipv6

• mcast-ipv4

• mcast-ipv6

• vpn-ipv4

• vpn-ipv6

• evpn

• flow-ipv6

• label-ipv4

• label-ipv6

• bgp-ls

When a VPRN has a neighbor identified by an IPv4 address, and therefore the transport is IPv4 TCP, the following MP-BGP address families are supported:

• ipv4

• ipv6

• mcast-ipv4

• mcast-ipv6

• flow-ipv4

• flow-ipv6

• label-ipv4

When a VPRN has a neighbor identified by an IPv6 address, and therefore the transport is IPv6 TCP, the following MP-BGP address families are supported:

• ipv4

• ipv6

• mcast-ipv4

• mcast-ipv6

• flow-ipv6
