Importing Routes from Other Protocols

You can import routing information from other protocols into the DVMRP routing table. Only routes that appear in the RPF table can be imported.

Note: If you want to use IS-IS, OSPF, or RIP routes, you must make those routes available to multicast protocols. See Defining Static Routes for Reverse-Path Forwarding.

  1. Issue the router dvmrp command in Global Configuration mode to access Router Configuration mode. You can create and enable DVMRP processing on a VR from the Router Configuration mode.
    host1:boston(config)#router dvmrp

    Use the no version to remove DVMRP from the VR.

  2. Specify a route map using the route-map command in Global Configuration mode.
    host1:boston(config-router)#route-map boston-map atm 3/2

    Use the no version to delete the route map. If you do not specify an interface, it removes the global route map if one exists.

  3. Import information from one type of routing domain into another using the redistribute command in Router Configuration mode.

    Example—Importing routing information from BGP into DVMRP

    host1:boston(config-router)#redistribute bgp 100 route-map boston-map

    Use the no version to disable redistribution.
