Locating information loss and reducing configuration faults can be realized by
tracing the network path of the specified (S, G, RP) entries. After the transmission
path of SA messages is determined, the overflow of SA messages can be avoided
by the correct configuration.

Network requirements
In the following network environment shown in Figure 9-3, four 3Com Switch
8800 Family series routing switches are in the different PIM-SM domains with no
BGP or MBGP running among them.
To enable Switch D to receive the specified source information from PIM-SM
domains 1, 2 and 3, you can configure static RPF peers with the parameter
rp-policy .
After the configuration is complete, Switch D will only receive SA messages
permitted by the corresponding filtering policy from its static RPF peers.
