Multicast Static Route Fails to Take Effect

Multicast Static Route Fails to Take Effect

Fault Description

A device does not run any dynamic routing protocols, and a multicast static route is configured on the device. Multicast data cannot be forwarded to user hosts through this multicast static route even though the physical status and link-layer protocol status of the interface are both Up.

Procedure

  1. Check whether the multicast static route is configured correctly and has been added to the multicast routing table.

    Run the display multicast routing-table static command to check whether the multicast static route is configured correctly.

    If the multicast static route is not configured correctly or does not match the network topology because the topology has changed, the multicast routing table will not contain the routing entry or configuration of the multicast static route. In this case, run the ip rpf-route-static command to configure a multicast static route that matches the current network topology.

  2. Check whether the multicast static route has been added to the routing table of the specified routing protocol.

    If a routing protocol has been specified for the multicast static route, run the display ip routing-table command to check whether this route has been added to the routing table of the protocol. If not, configure a matching unicast route for the routing protocol.

  3. Check whether the multicast static route matches the specified routing policy.

    If a routing protocol has been specified for the multicast static route, run the display route-policy command to check whether the source address of the multicast static route matches the routing policy. If not, run the route-policy command to change the matching rule of the routing policy. Ensure that the multicast static route matches the routing policy and can be added to the routing table.
