Configure a BGP Peer with MP-BGP for IPv4 Multicast

After you Configure BGP, configure a BGP peer with MP-BGP for IPv4 multicast if you want your BGP peer to be able to learn and pass IPv4 multicast routes in BGP updates. You’ll be able to separate unicast from multicast traffic, or employ the features listed in MP-BGP to use only routes from the unicast or multicast route table, or routes from both tables.
If you want to support multicast traffic only, you must use a filter to eliminate unicast traffic.
The firewall doesn’t support ECMP for multicast traffic.
  1. Enable MP-BGP extensions so that a BGP peer can exchange IPv4 multicast routes.
    1. Select
      Network
      Virtual Routers
      and select the virtual router you are configuring.
    2. Select
      BGP
      .
    3. Select
      Peer Group
      , select a peer group and a BGP peer.
    4. Select
      Addressing
      .
    5. Select
      Enable MP-BGP Extensions
      .
    6. For
      Address Family Type
      , select
      IPv4
      .
    7. For
      Subsequent Address Family
      , select
      Unicast
      and then
      Multicast
      .
    8. Click
      OK
      .
  2. (
    Optional
    ) Create an IPv4 static route and install it in the multicast route table only.
    You would do this to direct multicast traffic for a BGP peer to a specific next hop, as shown in the topology in MP-BGP.
    1. Select
      Network
      Virtual Routers
      and select the virtual router you are configuring.
    2. Select
      Static Routes
      IPv4
      and
      Add
      a
      Name
      for the route.
    3. Enter the IPv4
      Destination
      prefix and netmask.
    4. Select the egress
      Interface
      .
    5. Select the
      Next Hop
      as
      IP Address
      and enter the IP address of the next hop to which you want to direct multicast traffic for this static route.
    6. Enter an
      Admin Distance
      .
    7. Enter a
      Metric
      .
    8. For
      Route Table
      , select
      Multicast
      .
    9. Click
      OK
      .
  3. Commit the configuration.
    Click
    Commit
    .
  4. View the route table.
    1. Select
      Network
      Virtual Routers
      .
    2. In the row for the virtual router, click
      More Runtime Stats
      .
    3. Select
      Routing
      Route Table
      .
    4. For
      Route Table
      , select
      Unicast
      or
      Multicast
      to display only those routes.
    5. For
      Display Address Family
      , select
      IPv4 Only
      ,
      IPv6 Only
      , or
      IPv4 and IPv6
      to display only routes for that address family.
  5. To view the Forwarding table, BGP Local RIB, or BGP RIB Out table, see Configure a BGP Peer with MP-BGP for IPv4 or IPv6 Unicast.
