Example 2: Application of MSDP Mesh-Group.
Mesh-Group can be used to reduce flooding of SA messages. The Peers which are meshed in the same
domain can be configured as a Mesh-Group. All the members in the same mesh group use a unique group
name.
As it is shown in Figure, when Mesh-Group is configured for the four meshed Peers in the same domain,
flooding of SA messages reduced remarkably.
