ISIS Mesh Groups – RFC2973

Mesh groups are used to reduce the number of LSPs being sent and received by a set of nodes within an ISIS area. If a node forms part of a mesh group it will only receive one copy of an LSP from all of the nodes within that mesh group. Mesh groups are useful when there is a dense flooding area available to nodes within an ISIS area.

To configure interfaces into a mesh group they need to be added into a mesh group number within the ISIS protocol :
protocols {
     isis {
          interface ge-0/0/1.0 {
               mesh-group 1;
          }
     }
}
