BIDIR-PIM configuration example
Network requirements
In the BIDIR-PIM domain shown in Figure 48, Source 1 and Source 2 send different multicast information
to multicast group 225.1.1.1. Host A and Host B receive multicast information from the two sources.
Serial 3/1/1 of Router C acts as a C-BSR, and loopback interface 0 of Switch C acts as a C-RP of the
BIDIR-PIM domain.
IGMPv2 runs between Router B and Host A and between Router D and Host B.

Configuration procedure
1. Assign an IP address and subnet mask to each interface according to Figure 48. (Details not
shown.)
2. Configure OSPF on the routers in the BIDIR-PIM domain to make sure they are interoperable at the
network layer. (Details not shown.)
3. Enable IP multicast routing, PIM-SM, BIDIR-PIM, and IGMP:
# On Router A, enable IP multicast routing, enable PIM-SM on each interface, and enable
BIDIR-PIM.
