Usage
Information
An 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 cannot forward the SA message to other members of the mesh-group.
