NOTE:
If only one MSDP peer is configured on a router, this MSDP peer is registered as a static RPF peer.

Configuring an MSDP peer connection

This section describes how to configure an MSDP peer connection.

Configuration prerequisites

Before you configure an MSDP peer connection, complete the following tasks:
• Configure any unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
Configure basic MSDP functions.
•
Determine the description of MSDP peers.
•
• Determine the name of an MSDP mesh group.
Determine the MSDP peer connection retry interval.
•
Determine the password for MD5 authentication used by both MSDP peers to establish a TCP
•
connection.

Configuring MSDP peer description

MSDP peer descriptions help the administrator easily distinguish different MSDP peers and better
manage MSDP peers.
To configure the description for an MSDP peer:
Step
1. Enter system view.
2. Enter public network MSDP
view or VPN instance MSDP
view.
3. Configure the description for
an MSDP peer.

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 from outside the mesh group that passed
the RPF check 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.
