mesh-group enable

Usage Scenario

When concurrent links exist between the FW and its neighbor, the mesh-group enable command enables the mesh-group function. The router ID of a neighboring router uniquely identifies a mesh group. After LSAs are received, the FW selects a primary link to flood the received LSAs, without performing reverse flooding. This prevents repeated flooding, reduce the load on the links, and save system resources.

Interfaces that meet the following conditions can form a mesh group:

• The interfaces belong to the same area and OSPF process.
• The neighbor status is Exchange or Full.
• Each interface is connected only to one neighbor.

Precautions

After the router is enabled with the mesh-group function, if the router IDs of the directly connected neighbor routers are the same, the LSDBs of the entire network cannot be synchronized and routes cannot be calculated correctly. In this case, you need to reconfigure the router ID of the neighbor, and then restart the neighbor to validate the configured router ID.
