View

Parameter
peer-address: Address of the static RPF peer receiving SA messages.
rp-policy ip-prefix-name: Specifies a filtering policy based on RP addresses to filter
RPs in SA messages. ip-prefix-name is the IP address prefix list, in the range of 1 to 19
characters.
Description
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.
By default, no static RPF peer is configured.
If only one MSDP peer is configured with the peer command, the MSDP peer will be
regarded as a static RPF peer. When configuring multiple static RPF peers for the
same router, you must follow the following two configuration methods::
In the case that all the peers use the rp-policy keyword: Multiple static RPF peers
take effect at the same time. RPs in SA messages are filtered according to the
prefix list configured; only SA messages whose RP addresses pass the filtering
are received. If multiple static RPF peers using the same rp-policy keyword are
configured, when any of the peers receives an SA message, it will forward the SA
message to the other peers.
In the case that none of the peers use the rp-policy keyword: According to the
configuration sequence, only the first static RPF peer whose connection state is
UP is active. All the SA messages from this peer will be received and those from
other static RPF peers will be discarded. Once the active static RPF peer fails
(because the configuration is removed or the connection is terminated), based on
the configuration sequence, the subsequent first static RPF peer whose
connection is in the UP state will be selected as the active static RPF peer.
