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.
