Please perform the following configurations in MSDP view.
Table 476 Control the received source information
Operation
Filter off the SA messages from a specified
MSDP peer
Receive the SA messages permitted by the
advanced ACL from a specified MSDP peer
Remove the filtering rule over received source
information
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.
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.
Table 477 Configure MSDP full connection group
Operation
Configure an MSDP peer to be a member of
an MSDP Mesh Group
Delete that member from the Group
If an MSDP peer is configured into different mesh groups, only the last
configuration is valid.
Perform the following configurations in MSDP view.
Table 478 Configure the MSDP connection retry period
Operation
Configuring the MSDP connection retry
period
Restore the default value of MSDP connection
retry interval
By default, MSDP connection is retried at the interval of 30 seconds.
The session between MSDP peers can be cut off and re-activated as needed.
If a session between MSDP peers is cut off, the TCP connection will terminate with
no retry effort, but the configuration information will be reserved.
Please perform the following configurations in MSDP view.
