You have a multicast application where the servers send packets less frequently than the standard PIM timeout intervals.
PIM-SM is best suited to this type of application. The configurations of the RP and BSR or Auto-RP routers for this example are identical to those shown in Recipes 23.2 and 23.3. The differences appear on the other routers in the network. So this recipe shows only the configurations for these other routers:
configure terminalEnter configuration commands, one per line. End with CNTL/Z. Router1(config)#
ip pim spt-threshold
ip pim sparse-dense-modeRouter1(config-if)#
ip pim sparse-modeRouter1(config-if)#
Discussion of multicast applications usually focuses on high-bandwidth applications. But some multicast applications have the opposite behavior. For example, some news broadcast type applications allow message servers to send short messages to a large group of users. This sort of service might be used for administrative purposes (“the server is going down in five minutes”) or for business ...
