Referenced route type: multicast static
Route selection rule: preference-preferred
Load splitting rule: disable
The output shows that the RPF route on Router B has changed. It is now the configured static
multicast route, and the RPF neighbor is now Router C.
Creating an RPF route
Network requirements
PIM-DM runs in the network and all routers in the network support IP multicast. Router B and Router C run
OSPF, and have no unicast routes to Router A. Typically, Receiver can receive the multicast data from
Source 1 in the OSPF domain.
Perform the following configuration so that Receiver can receive multicast data from Source 2, which is
outside the OSPF domain.

Configuration procedure
1. Assign an IP address and subnet mask to each interface according to Figure 23. (Details not
shown.)
2. Enable OSPF on Router B and Router C to make sure they are interoperable at the network layer
and they can dynamically update their routing information. (Details not shown.)
3. Enable IP multicast routing, and enable PIM-DM and IGMP:
# Enable IP multicast routing on Router C, enable PIM-DM on each interface, and enable IGMP on
GigabitEthernet 2/0/1.
