Use the undo isis enable command to disable this configuration.
The interface does not enable the IS-IS routing process by default.
Before running IS-IS protocol normally, you must use the isis command to enable
IS-IS process, and use the network-entity command to configure a network entity
title (NET) for the router, and then use the isis enable command to enable each
interface that need to run the IS-IS process.
Related command: isis, and network-entity.
Example
# Enable the IS-IS routing process on Vlan-interface 10.

4.1.23 isis mesh-group

Syntax
isis mesh-group { mesh-group-number | mesh-blocked }
undo isis mesh-group
View
Interface view
Parameter
mesh-group-number: Mesh group number, ranging from 1 to 4,294,967,295.
mesh-blocked: After this parameter is configured, the interface will be blocked to
flood the received LSP to other interfaces.
Description
Use the isis mesh-group command to add an interface to a specified mesh group.
Use the undo isis mesh-group command to delete an interface from a mesh group.
An interface is not in any mesh group and can flood LSP normally by default.
For an interface not in a mesh group, it follows the normal process to flood the
received LSP to other interfaces. For the NBMA network with high connectivity and
multiple point-to-point links, this will cause repeated LSP flooding and bandwidth
waste.
