z
It is required to configure the anycast RP application so that the receiver-side DRs and the
source-side DRs can initiate a Join message to their respective RPs that are the topologically
nearest to them.
z
On Switch B and Switch D, configure the interface Loopback 10 as a C-BSR, and Loopback 20 as
a C-RP.
z
The router ID of Switch B is 1.1.1.1, while the router ID of Switch D is 2.2.2.2. Set up an MSDP
peering relationship between Switch B and Switch D.

Configuration procedure
1) Configure
IP
addresses and unicast routing
Configure the IP address and subnet mask for each interface as per
. Detailed configuration
steps are omitted here.
Configure OSPF for interconnection between the switches. Ensure the network-layer interoperation
among the switches, and ensure the dynamic update of routing information between the switches
through a unicast routing protocol. Detailed configuration steps are omitted here.
2) Enable IP multicast routing, and enable PIM-SM and IGMP
