8.3 Configuring Connection between MSDP Peers

An AS may contain multiple MSDP peers. To avoid SA flooding between the MSDP
peers, you can use the MSDP mesh mechanism to improve traffic. When multiple
MSDP peers are fully connected with one another, these MSDP peers form a mesh
group. When an MSDP peer in the mesh group receives SA messages from outside the
mesh group, it sends them to other members of the group. On the other hand, a mesh
group member does not perform RPF check on SA messages from within the mesh
group and does not forward the messages to other members of the mesh group. This
avoids SA message flooding since it is unnecessary to run BGP or MBGP between
MSDP peers, thus simplifying the RPF checking mechanism.
The sessions between MSDP peers can be terminated and reactivated sessions as
required. When a session between MSDP peers is terminated, the TCP connection is
closed, and there will be no reconnection attempts. However, the configuration
information is kept.
8.3.1 Configuration Prerequisites
Before configuring an MSDP peer connection, you need to configure:
A unicast routing protocol
Basic functions of IP multicast
PIM-SM basic functions
MSDP basic functions

For an area containing only
one MSDP peer, if the BGP
or MBGP does not run in this
area, you need to configure
a static RPF peer.
