Cisco Systems 78-11741-02 manual Redistributing Dvmrp Routes into Multiprotocol BGP, Redistributed

Configuring Multiprotocol BGP Extensions for IP Multicast

Multiprotocol BGP Configuration Task List

subject it to route map conditions. If you supply a route map, you can specify various match criteria options for the multiprotocol BGP routes. If the route passes the route map, then the route is redistributed into DVMRP.

If there are multicast sources in other routing domains that are known via multiprotocol BGP and there are receivers in a DVMRP cloud, they will want to receive packets from those sources. Therefore, you need to redistribute the multiprotocol BGP prefix routes into DVMRP. This will be the scenario when distributing multiprotocol BGP prefixes into the MBONE.

To redistribute multiprotocol BGP routes into DVMRP, use the following command in interface configuration mode:

Command	Purpose
Router(config-if)#ip dvmrp metric metric [route-map	Redistributes multiprotocol BGP routes into DVMRP with a
map-name]mbgp	specified metric. An optional route map controls which routes
	are redistributed; otherwise, all multiprotocol BGP routes are
	redistributed.

Redistributing DVMRP Routes into Multiprotocol BGP

If there are multicast sources in a DVMRP routing domain that need to reach receivers in multiprotocol BGP routing domains, you need to redistribute DVMRP prefixes into multiprotocol BGP. If you supply a route map, you can also use the set route-map configuration commands to specify various BGP attribute settings.

To redistribute DVMRP prefixes into multiprotocol BGP, use the following command in address family configuration mode:

Command	Purpose
Router(config-router-af)# redistribute dvmrp	Redistributes DVMRP routes into multiprotocol BGP.
[route-map map-name]

To redistribute DVMRP prefixes into multiprotocol BGP, use the following command in router configuration mode:

Command	Purpose
Router(config-router)#redistribute dvmrp [route-map	Redistributes DVMRP routes into multiprotocol BGP.
map-name]

See the “Multiprotocol BGP Route Redistribute Examples” section for an example of redistributing DVMRP routers into a multiprotocol BGP routing domain.
