Description
Configuring an MSDP
Mesh Group
ONFIGURATION
Before configuring MSDP peer connection, complete the following tasks:
Configuring any unicast routing protocol so that all devices in the domain are
■
interoperable at the network layer
Configuring basic functions of MSDP
■
Before configuring an MSDP peer connection, prepare the following data:
Description information of MSDP peers
■
Name of an MSDP mesh group
■
MSDP peer connection retry interval
■
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:
To do...
Enter system view
Enter public instance MSDP

Configure description for an
MSDP peer
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 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 with these MSDP peers.
Follow these steps to create an MSDP mesh group:
To do...
Enter system view
Use the command...
system-view
msdp [ vpn-instance
vpn-instance-name ]
peer peer-address

Use the command...
