Configuring MSDP Peer Description
With the MSDP peer description information, the administrator can easily distinguish different MSDP
peers and thus better manage MSDP peers.
Follow these steps to configure description for an MSDP peer:

Configuring an MSDP Mesh Group
An AS may 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.
On one hand, an MSDP peer in an MSDP mesh group forwards SA messages from outside the mesh
group that have passed the RPF check to the other members in the mesh group; on the other hand, 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 either. This mechanism not only avoids SA
flooding but also simplifies the RPF check mechanism, because BGP or MBGP is not needed to run
between these MSDP peers.
By configuring the same mesh group name for multiple MSDP peers, you can create a mesh group
assign those MSDP peers to that mesh group.
