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 NetworkVirtual 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 NetworkVirtual Routers and select the virtual router you are configuring.
    2. Select Static RoutesIPv4 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 NetworkVirtual Routers.
    2. In the row for the virtual router, click More Runtime Stats.
    3. Select RoutingRoute 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.
