Usage 
Information
A MSDP mesh group is a mechanism for reducing SA flooding, typically in an intra-domain 
setting. When some subset of a domain’s MSDP speakers are fully meshed, they can be 
configured into a mesh-group. If member X of a mesh-group receives a SA message from an 
MSDP peer that is also a member of the mesh-group, member X accepts the SA message and 
forwards it to all of its peers that are not part of the mesh-group. However, member X can not 
forward the SA message to other members of the mesh-group.
