28.5.3 ANYCAST RP Configuration Examples

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 register message

to RP2 to guarantee that all orders that already join RP2 can find the multicast source. 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 register message, it can use the self-r-address, which identifies itself as

the source address to forward the register message to RP2. The cloud in the Figure

represents the PIM-SM network operation between RP1 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

Switch(config)#ip pim rp-candidate loopback1

Switch(config)#ip pim bsr-candidate vlan 1

Switch(config)#ip pim multicast-routing
