Configuring An Msdp Peer Connection - HP A8800 Configuration Manual

Configuring an MSDP peer connection

Configuration prerequisites
Before configuring 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 information of MSDP peers.
Determine the name of an MSDP mesh group.
•
Determine the MSDP peer connection retry interval.
•
Determine the MD5 authentication password for the TCP connection to be established with an
•
MSDP peer.
Configuring MSDP peer description
With the MSDP peer description information, the administrator can easily distinguish different MSDP
peers and thus better manage MSDP peers.
To configure description for an MSDP peer:
Step
1. Enter system view.
2. Enter public network MSDP
view or VPN instance MSDP
view.
3. 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 and
assign those MSDP peers to that mesh group.
Before grouping multiple routers into an MSDP mesh group, make sure that these routers are
interconnected with one another.
The mesh group name must be the same for all the peers.
