CAUTION:
■ Before grouping multiple devices into an MSDP mesh group, make sure that
these devices are interconnected with one another.
■ Make sure to configure the same mesh group name on each peer.
■ If you configure more than one mesh group name on an MSDP peer, only the
last configuration is effective.
Configuring MSDP Peer
Connection Control
MSDP peers are interconnected over TCP. 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:

Prerequisites
Before configuring SA message related parameters, complete the following tasks:
■ Configure any unicast routing protocol so that all devices in the domain are
interoperable at the network layer.
