Configuration Guide - IP Routing
The IS-IS interface is configured to automatically adjust the link cost based on link quality.
By default, an IS-IS interface does not have this function.
The cost parameter specifies the link cost adjustment value. After this parameter is specified:
l If the link quality changes from good to low, the link cost equals the original link cost plus the adjustment
l If the link quality changes from low to good, the orginal link cost applies.

Example
On a Level-1 device, run the display isis route command to check IS-IS routing information.
If the Level-1-2 device is enabled to leak IS-IS routes in the Level-2 area to Level-1 areas, the
output of the display isis route command is similar to the following information. For example,
the route 192.168.1.0/24 in the Level-2 area is displayed, and Up/Down is U.
<HUAWEI> display isis route

0.0.0.0/0
192.168.1.0/24
10.1.1.0/24
20.1.1.0/24
On the Level-1-2 device, run the display isis lsdb verbose command to check whether the
Level-1-2 device has leaked the route 192.168.1.0/24 to Level-1 areas.

value. If the new link cost exceeds the maximum link cost allowed, the maximum link cost allowed applies:
l The maximum link cost is 63, if the cost type is narrow, narrow-compatible, or compatible.
l The maximum link cost is 16777214, if the cost type is wide or wide-compatible.
Run the display isis route [ process-id | vpn-instance vpn-instance-name ] [ ipv4 ]
[ verbose | [ level-1 | level-2 ] | ip-address [ mask | mask-length ] ]
to check IS-IS routing information.
Run the display isis lsdb [ { level-1 | level-2 } | verbose | { local | lsp-id | is-name symbolic-
