Multiprotocol BGP (MP-BGP) Configuration

Hello Brian,

With MP-BGP, there’s basically two things:

  • The session itself, established through IPv4 or IPv6 and TCP is the transport protocol.
  • The stuff we advertise…different address families: IPv4 unicast, IPv6 unicast, IPv6 unicast, IPv6 multicast, VPN routes, etc.

It’s best to see the stuff that we advertise as “objects” or something. Once a session is established, you can advertise whatever you want. It’s possible to have an IPv4 neighbor adjacency and advertise IPv6 prefixes or the other way around, an IPv6 neighbor adjacency and advertise IPv4 prefixes. It also makes sense…it’s better to have a single neighbor adjacency and advertise anything you need through that single session.

Technically, when you use IPv6 you can call it TCP/IPv6.
