Configuring an MSDP
Mesh Group
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.
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
■
You can configure description information for each MSDP peer to manage and
memorize the MSDP peers.

information for an MSDP peer
If you configure RPs with the same address for two routers in the same PIM-SM
domain, the two routers will be MSDP peers to each other. To prevent failure of
RPF check on SA messages between MSDP peers, you must configure the RP
address to be carried in the SA messages.

In Anycast RP application, C-BSR and C-RP must be configured on different devices
or ports.
Configure a mesh group name on all the peers that will become members of the
MSDP mesh group so that the peers are fully connected with one another in the
mesh group.
