used to enable each interface which needs to run the IS-IS process. The IS-IS 
protocol is actually enabled upon the completion of these configurations.

isis mesh-group { mesh-group-number | mesh-blocked }

Interface view

mesh-group-number: Specifies the mesh group number, ranging from 1 to 
4,294,967,295.

mesh-blocked: Configures to block a specified interface, so that it will not flood 
the received LSP to other interfaces.

Use the isis mesh-group command to add an interface to a specified mesh 
group.

Use the undo isis mesh-group command to delete this interface from the mesh 
group.

By default, the interface does not belong to any mesh group and floods LSP 
normally.

The interface beyond the mesh group floods the received LSP to other interfaces, 
following the normal procedure. 

The interface joining a mesh group only floods the received LSP to the interfaces 
beyond the local mesh group.

Make sure to provide some redundancy when adding an interface to a mesh 
group or blocking it, avoiding the affect to the normal flooding of the LSP due to 
link failure.

# Add Vlan-interface 20 running IS-IS to mesh group 3.
