R2511-HP MSR Router Series IP Multicast Command Reference(V5)

189
Default
No static RPF peer is configured.
Views
Public network MSDP view, VPN instance MSDP view
Default command level
2: System level
Parameters
peer-address: Specifies an MSDP peer.
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.
Usage guidelines
When you configure multiple static RPF peers, observe the follow rules:
• If you use the rp-policy keyword for all the static RPF peers, all the static RPF peers take effect
concurrently. SA messages are filtered as per the configured prefix list and only those SA messages
whose RP addresses pass the filtering are accepted. If multiple static RPF peers use the same filtering
policy at the same time, when a peer receives an SA message, it forwards the SA message to the
other peers.
• 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 up state is activated. All SA messages
from this peer are accepted but the SA messages from other static RPF peers are 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 is selected as the
activated RPF peer according to the configuration sequence.
