    Configure a BGP Peer with MP-BGP for IPv4 or IPv6 Unicast

    After you Configure BGP, configure a BGP peer with MP-BGP for IPv4 or IPv6 unicast for either of the following reasons:
    • To have your BGP peer carry IPv6 unicast routes, configure MP-BGP with the Address Family Type of
      IPv6
       and Subsequent Address Family of
      Unicast
       so that the peer can send BGP updates that include IPv6 unicast routes. BGP peering (Local Address and Peer Address) can still both be IPv4 addresses, or they can both be IPv6 addresses.
    • To perform BGP peering over IPv6 addresses (
      Local Address
       and
      Peer Address
       use IPv6 addresses).
    The following task shows how to enable a BGP peer with MP-BGP so it can carry IPv6 unicast routes, and so it can peer using IPv6 addresses.
    The task also shows how to view the unicast or multicast route tables, and how to view the forwarding table, the BGP local RIB, and BGP RIB Out (routes sent to neighbors) to see routes from the unicast or multicast route table or a specific address family (IPv4 or IPv6).
    1. Enable MP-BGP Extensions for a peer.
      Configure the following so that a BGP peer can carry IPv4 or IPv6 unicast routes in Updates packets and the firewall can use IPv4 or IPv6 addresses to communicate with its peer.
      1. Select
        Network
        Virtual Routers
         and select the virtual router you are configuring.
      2. Select
        BGP
        .
      3. Select
        Peer Group
         and select a peer group.
      4. Select a BGP peer (router).
      5. Select
        Addressing
        .
      6. Select
        Enable MP-BGP Extensions
         for the peer.
      7. For
        Address Family Type
        , select
        IPv4
         or
        IPv6
        . For example, select IPv6.
      8. For
        Subsequent Address Family
        ,
        Unicast
         is selected. If you chose
        IPv4
         for the Address Family, you can select
        Multicast
         also.
      9. For
        Local Address
        , select an
        Interface
         and optionally select an
        IP
         address, for example, 2001:DB8:55::/32
      10. For
        Peer Address
        , enter the peer’s
        IP
         address, using the same address family (IPv4 or IPv6) as the Local Address, for example, 2001:DB8:58::/32.
      11. Select
        Advanced
        .
      12. (
        Optional
        )
        Enable Sender Side Loop Detection
        . When you enable Sender Side Loop Detection, the firewall will check the AS_PATH attribute of a route in its FIB before it sends the route in an update, to ensure that the peer AS number is not on the AS_PATH list. If it is, the firewall removes it to prevent a loop
      13. Click
        OK
        .
    2. (
      Optional
      ) Create a static route and install it in the unicast route table because you want the route to be used only for unicast purposes.

        , and
        Add
         a route.
      3. Enter a
        Name
         for the static route.
      4. Enter the IPv4 or IPv6
        Destination
         prefix and netmask, depending on whether you chose IPv4 or IPv6.
      5. Select the egress
        Interface
        .

        Next Hop
         as
        IPv6 Address
         (or
        IP Address
         if you chose IPv4) and enter the address of the next hop to which you want to direct unicast traffic for this static route.
