Configuring Static RPF
Peers

Table 466 Configure MSDP peers
Operation
Configure MSDP peers
Remove MSDP peer configuration
Add description to a MSDP peer
Remove the description
The command to add description is optional.
If the local router is also in BGP Peer relation with a MSDP peer, the MSDP peer
and the BGP peer should use the same IP address.
Not any two routers between which MSDP peer relationship has been established
must run BGP or MBGP, so long as they have a BGP or MBGP route between them.
If no BGP of MBGP route exists between them, then you must configure static RPF
peers.
Please perform the following configurations in MSDP view.
Table 467 Configure static RPF peers
Operation
Configure static RPF peers
Remove static RPF peer configuration
By default, no static RPF peer is configured.
The peer command must be configured before the configuration of
■
static-rpf-peer command.
If only one MSDP peer is configured via the peer command, the MSDP peer will
■
be regarded as the static RPF peer.
To configure multiple static RPF peers at the same time, take any of the two
methods:
Using rp-policy parameters universally: Multiple static RPF peers take effect at
■
the same time and SA messages are filtered by the RP addresses contained
according to the configured prefix list. If multiple static RPF peers using the
same rp-policy parameter are configured, any peer that receives an SA
message will forward it to the other peers.
Not using the rp-policy parameter universally: According to the configuration
■
sequence, only the first static RPF peer whose connection state is UP is
activated. All SA messages from the peer will be received and those from other
static RPF peers will be discarded. Once the activated static RPF peer turns
invalid (possibly out of configuration removed or connection interrupted), the
following first static RPF peer with UP connection state according to the
configuration sequence will assume its role.
