Configuring MSDP mesh groups

Configure mesh groups to reduce SA flooding. A mesh group does not forward SA messages to other group members. The originator, which is also a mesh group member, forwards SA messages to all group members. Create MSDP mesh groups from a group of meshed MSDP speakers from a domain.

Note

The MSDP router does not belong to any mesh group by default.

1. Enter either Global Configuration mode or VRF Router Configuration mode for a specific VRF context:

   enable

   configure terminal

   Optional: router vrf WORD<1-16>

2. Configure the MSDP mesh group:

   ip msdp mesh-group WORD<1-64> {A.B.C.D}

Example

Switch:1>enable

Switch:1#configure terminal

Switch:1(config)#ip msdp mesh-group helloworld 21.0.0.2
