  1. Thank you Rene for the detailed reply. Just so I fully understand all the options, I can technically have the following:

    1. MP-BGP arrangement with IPv4 neighbor establishment and then advertisement of both IPv4 and IPv6 prefixes
    2. MP-BGP arrangement with IPv6 neighbor establishment and then advertisement of both IPv4 and IPv6 prefixes
    3. MP-BGP arrangement with both IPv4 and IPv6 neighbor establishment and then advertisement of IPv4 prefixes within IPv4 address family and IPv6 prefixes within IPv6 address family

    Please confirm when you have a chance. Many thanks.

  2. BGP by default, only has the IPv4 unicast family activated so you can advertise IPv4 unicast prefixes, that’s it. By enabling other address families, you can advertise things like multicast routes or VPN routes. BGP doesn’t use multicast addresses itself, it will always use a TCP session between two neighbors, that’s it.

  3. diff AS so the route-map to change the NEXTHOP has to be applied outbound not inbound i hv tested it

  4. Hi,
    I had worked this lab in IPV4 before but when I got to this I was confused a bit.

    You had the following:

    I see that you go into the address-family ipv4 and I am good there but then I see you do the no activate on the ipv6. Here is where I am confused; have yet to find granular details and also checking my kindle book for info as well:

  5. 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 prefixe
