Configuring a Virtual Multiaccess Network

You can specify that interfaces within a given mesh group act as a virtual multiaccess network.

isis mesh-group

Use when you want interfaces in the same mesh group to act as a virtual multiaccess network.
LSPs seen on one interface in a mesh group are not flooded to another interface in the same mesh group.
Example host1(config-if)#isis mesh-group blocked
Use the no version to disable the feature.
