Multicast Server
As shown in the Figure, the overall net work environment is PIM-SM, which provides two routers supporting
ANYCAS T RP, RP1 and RP2. Onc e 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 rec eives 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 ANY CAST list maintained on router RP1 that has been configured with A NYCAS T 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 sourc e address to forward the
register message to RP 2. The cloud in the Figure repres ents the PIM-SM network operation between RP1
and RP2.
The following is the configuration steps:
RP1 Configuration:
