30.4 MSDP Configuration Examples
30.4.1 Configuring Static RPF Peers
I. Networking requirements
In the following networking environment, four Switch 8800s all are in the PIM-SM
domains with no BGP or MBGP running among them (Note that MBGP is not supported
in the basic code; the extended option is required).
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.
