peer-address: MSDP peer address.  

rp-policy ip-prefix-name: Specifies a filtering policy based on the RP address in SA messages, where 

ip-prefix-name is the filtering policy name, a case sensitive string of 1 to 19 characters. A policy name 

must not contain any space. 

Use the static-rpf-peer command to configure a static RPF peer.  

Use the undo static-rpf-peer command to remove a static RPF peer.  

No static RPF peer is configured by default.  

When you configure multiple static RPF peers, observe the follow rules:  

1)  If you use the rp-policy keyword for all the static RPF peers, all the static RPF peers take effect 

concurrently. SA messages will be filtered as per the configured prefix list and only those SA 

messages whose RP addresses pass the filtering will be accepted. If multiple static RPF peers use 

the same filtering policy at the same time, when a peer receives an SA message, it will forward the 

SA message to the other peers.  

2)  If you use the rp-policy keyword for none of the static RPF peers, according to the configuration 

sequence, only the first static RPF peer whose connection is in the UP state will be activated, and 

all SA messages from this peer will be accepted while the SA messages from other static RPF 

peers will be discarded. When this active static RPF peer fails (for example, when the configuration 

is removed or when the connection is torn down), still the first RPF peer whose connection is in UP 

state will be selected as the activated RPF peer according to the configuration sequence.
