Configuring An Ip Multicast Static Route; Changing The Distance For A Unicast Multicast Route - Motorola BSR 2000 Configuration And Management Manual

Release 1.0

Configuring an IP Multicast Static Route

IP multicast static routes (mroutes) enable unicast and multicast packets to take
different paths over combined multicast and unicast network topologies by allowing
multicast packets to travel from the router that is configured with the static multicast
route to the next multicast router, even if there are one or more unicast routers in the
path. The router with the multicast static route uses the IP static multicast route
configuration instead of the unicast routing table to determine the path, and no
information about this IP multicast static route is advertised or redistributed to any
other router on the network.
Use the ip mroute command in Global Configuration mode to place a multicast static
route which includes the multicast source address:
MOT(config)# ip mroute <A.B.C.D> <A.B.C.D> <A.B.C.D> [<1-255>]
where:

Changing the Distance for a Unicast Multicast Route

The distance value is used to compare with the same source in the unicast routing
table. The route that is configured with the lower administrative distance (which can
be either the route in the unicast routing table) takes precedence when computing the
Reverse Path Forwarding (RPF) interface for the source of a multicast packet.
If there are two paths to a source, one through unicast routing (using Protocol
Independent Multicast [PIM] as the multicast routing protocol) and another path using
DVMRP (unicast and multicast routing), and PIM must be the path to a source, use
the ip mroute unicast distance command in Global Configuration mode to increase
the default administrative distance for the DVMRP route:
MOT(config)# ip mroute unicast distance <1-255>

Clearing IP Multicast Information
A.B.C.D is the source IP address of the multicast static route.
A.B.C.D is the source subnetwork IP address of the multicast static route.
A.B.C.D is the Reverse Path Forwarding neighbor IP address or route.
1-255 is the optional administrative distance of the specific multicast static route.
1-255 is the administrative distance number for the multicast route.
