mesh-group

Syntax

mesh-group <MESH-NAME>

no mesh-group <MESH-NAME>

Description

Associates the given mesh group with the MSDP peer. This feature is used to reduce the amount of SA traffic in an intra-domain setting.

The no form of this command removes the peer from the currently configured mesh.

Command context

config-msdp-peer

Parameters

<MESH-NAME>

Specifies the MSDP mesh group name.

Authority

Administrators or local user group members with execution rights for this command.

Usage

All MSDP peers on the router that participate in the mesh group must be fully meshed with all other peers in the mesh group. When MSDP mesh groups are used, SA messages are not flooded to other mesh group peers. It also eliminates RPF checks on arriving SA messages. With MSDP mesh group configured, SA messages are always accepted from mesh group peers.

Example

Associating a mesh group with an MSDP peer:

switch(config-msdp-peer)# mesh-group test-mesh-group

Removing the MSDP peer from the configured mesh:

switch(config-msdp-peer)# no mesh-group test-mesh-group
