Configuring Description
Information for MSDP
Peers
You can configure description information for each MSDP peer to manage and 
memorize the MSDP peers.
Configuring Anycast RP
Application
If you configure RPs that have the same address on 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.
Configuring an MSDP
Mesh Group
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. 
Before you configure an MSDP mesh group, make sure the routers must be fully 
connected with one another.
The same group name must be configured on all the peers.
If you add the same MSDP peer into multiple mesh groups, only the latest 
configuration takes effect.
