48.5.3 ANYCAST RP Configuration Examples

Figure 48-6 The ANYCAST RP v4 function of the router

As shown in the Figure, the overall network environment is PIM-SM, which provides two routers supporting

ANYCAST RP, RP1 and RP2. Once multicast data from the multicast source server reaches the DR, the DR

will send a multicast source register message to the nearest RP unicast according to the unicast routing

algorithm, which is RP1 in this example. When RP1 receives the register message from the DR, besides

redistributing to the shared tree according to the orderers who already join it, it will forward the multicast

Since there is an ANYCAST list maintained on router RP1 that has been configured with ANYCAST RP, and

since this list contains the unicast addresses of all the other RP in the network, when the RP1 receives the

and RP2.

The following is the configuration steps:

RP1 Configuration:

Switch#config

Switch(config)#interface loopback 1

Switch(Config-if-Loopback1)#ip address 1.1.1.1 255.255.255.255

Switch(Config-if-Loopback1)#exit
