Similar to MSDP outbound filter in function, MSDP inbound filter controls the received
SA messages. By default, the SA messages from all peers are accepted.
30.2.11 Configuring MSDP Mesh Group
Mesh Group is useful when full connection among MSDP peers is required but SA
message flooding shall be prevented.
In a Mesh group, the SA messages from outside the group are forwarded to other
members in the group, but the SA messages from peers inside the group will not be
performed with Peer-RPF check or forwarded in the group. In this case, the overflow of
SA messages is avoided and Peer-RPF is simplified, as BGP or MBGP is not required
between MSDP peers.
Please perform the following configurations in MSDP view.
