Configuring MSDP peer description
With the MSDP peer description information, the administrator can easily distinguish different MSDP
peers to better manage MSDP peers.
To configure description for an MSDP peer:
Ste
p
Command
Remarks
1. Enter system view.
system-view N/A
2. Enter MSDP view.
msdp N/A
3. Configure description for an
MSDP peer.
peer peer-address description text
No description is configured for an
MSDP peer by default.
Configuring an MSDP mesh group
An AS can contain multiple MSDP peers. You can use the MSDP mesh group mechanism to avoid SA
message flooding among these MSDP peers and optimize the multicast traffic.
An MSDP peer in an MSDP mesh group forwards SA messages (that have passed the RPF check) from
outside the mesh group to the other members in the mesh group. A mesh group member accepts SA
messages from inside the group without performing an RPF check, and does not forward the message
within the mesh group. This mechanism not only avoids SA flooding but also simplifies the RPF check
mechanism because you do not need to run BGP or MBGP between these MSDP peers.
By configuring the same mesh group name for multiple MSDP peers, you can create a mesh group that
contains these MSDP peers.
IMPORTANT:
Before grouping multiple routers into an MSDP mesh group, make sure that these routers are
interconnected with one another.
To create an MSDP mesh group:
Ste
p
Command
Remarks
1. Enter system view.
system-view N/A
2. Enter MSDP view.
msdp N/A
3. Create an MSDP mesh group
and assign an MSDP peer to
that mesh group.
peer peer-address mesh-group
name
An MSDP peer does not belong to
any mesh group by default.
If you assign an MSDP peer to
multiple mesh groups, only the last
configuration is effective.
Configuring MSDP peer connection control
MSDP peers are interconnected over TCP (port number 639). You can flexibly control sessions between
MSDP peers by manually deactivating and reactivating the MSDP peering connections. When the
connection between two MSDP peers is deactivated, SA messages will no longer be delivered between
