Configuring concurrent meshing and routing

Concurrent meshing and routing is supported on 5400 v2 module and later products.


Since concurrent meshing and routing is only supported on V2 modules, the no allow-v1-modules configuration parameter must be set on switches that are configured for meshing and routing.

Meshing and routing can be configured simultaneously. A packet can be routed into a mesh, or be switched through a mesh and then routed. Two routers can be connected by mesh links, which offers additional network topologies between routers and switches. Concurrent meshing and routing makes it possible to implement meshing throughout a broadcast domain without the need for additional switches or the use of another Layer 2 technology such as Spanning Tree to connect meshing domains with routing switches.

It is important to remember that meshing provides Layer 2 load balancing only; two traffic streams going to the same router will take the same path through the mesh as the traffic is going to the same MAC address.


The mesh port on a switch is tagged on all VLANs on that switch. HPE recommends that every meshed switch have the same VLANs, whether they are used or not.
