Creating An Rpf Route - HP 4800G Series Configuration Manual

Creating an RPF Route

Network requirements
PIM-DM runs in the network and all switches in the network support IP multicast.
Switch B and Switch C run OSPF, and have no unicast routes to Switch 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) Configure IP addresses and unicast routing
Configure the IP address and subnet mask for each interface as per
configuration steps are omitted here.
Enable OSPF on Switch B and Switch C. Ensure the network-layer interoperation among Switch B and
Switch C. Ensure that the switches can dynamically update their routing information by leveraging the
unicast routing protocol. The specific configuration steps are omitted here.
2) Enable IP multicast routing, and enable PIM-DM and IGMP
# Enable IP multicast routing on Switch C, enable PIM-DM on each interface, and enable IGMP on the
host-side interface VLAN-interface 100.
