Before grouping multiple routers into an MSDP mesh group, make sure that
■
these routers are interconnected with one another.
If you configure more than one mesh group name on an MSDP peer, only the
■
last configuration is effective.
MSDP peers are interconnected over TCP (port number 639). You can flexibly
control sessions between MSDP peers by manually deactivating and reactivating
the MSDP peering connections. When the connection between two MSDP peers is
deactivated, SA messages will no longer be delivered between them, and the TCP
connection is closed without any connection setup retry, but the configuration
information will remain unchanged.
When a new MSDP peer is created, or when a previously deactivated MSDP peer
connection is reactivated, or when a previously failed MSDP peer attempts to
resume operation, a TCP connection is required. You can flexibly adjust the interval
between MSDP peering connection retries.
Follow these steps to configure MSDP peer connection control:
To do...
Enter system view
Enter public instance MSDP

Deactivate an MSDP peer
Configure the interval
between MSDP peer
connection retries
Before configuring SA message delivery, complete the following tasks:
Configure any unicast routing protocol so that all devices in the domain are
■
interoperable at the network layer.

Configuring basic functions of MSDP

■
Before configuring SA message delivery, prepare the following data:
Use the command...
msdp [ vpn-instance
vpn-instance-name ]
peer peer-address
mesh-group name
Use the command...
system-view
msdp [ vpn-instance
vpn-instance-name ]
shutdown peer-address
timer retry interval
