MROUTE
networks a deliberate choice is made to send multicast via different paths to those
used for unicast. In this case, the interface via which a multicast stream from a
given source enters a router may not be the same as the interface that connects to
the best unicast route to that source.
This command enables the user to statically configure the device with “multicast
routes” back to given sources. When performing the RPF check on a stream from a
given IPv4 source, the multicast routing protocol will look at these static entries as
well as looking into the unicast routing table. The route with the lowest
administrative distance - whether a static “multicast route” or a route from the
unicast route table - will be chosen as the RPF route to the source.
Note that in this context the term “multicast route” does not imply a route via
which the current router will forward multicast; instead it refers to the route the
multicast will have traversed in order to arrive at the current router.
Examples The following example creates a static multicast IPv4 route back to the sources in
the 10.10.3.0/24 subnet. The multicast route is via the host 192.168.2.3,
and has an administrative distance of 2:
awplus# configure terminal
awplus(config)# ip mroute 10.10.3.0/24 static 2 192.168.2.3 2
The following example creates a static multicast IPv4 route back to the sources in
the 192.168.3.0/24subnet. The multicast route is via the host 10.10.10.50.
The administrative distance on this route has the default value of 0:
awplus# configure terminal
awplus(config)# ip mroute 192.168.3.0/24 10.10.10.50
