NOTE:
If only one MSDP peer is configured on a router, this MSDP will be 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 Command
Remarks
1.
Enter system view.

2.
Enter public network MSDP
view or VPN instance MSDP
view.

Configure the description for
an MSDP peer.

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 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.
