Use the undo isis enable command to cancel this designation.
By default, the IS-IS routing process is not enabled on an interface.
For the normal operation of the IS-IS protocol, the isis command must be used to
enable the IS-IS process. Then the network-entity command is used to set a Network
Entity Title (NET) for the router. And, at last, the isis enable command is 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.
Related command: isis, network-entity.
Example
# Create an IS-IS routing process named “huawei”, and activate this routing process on
interface Vlan-interface 10.
[Quidway] isis huawei
[Quidway-isis] network-entity 10.0001.1010.1020.1030.00
[Quidway] interface 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: 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.
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 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. This processing method applied to an NBMA network
with higher connectivity and several point-to-point links will cause repeated LSP
flooding and waste bandwidth.
