View

Parameters
level-1: Specifies to set up only level-1 adjacency on the interface.
level-1-2: Specifies to set up level-1-2 adjacency on the interface.
level-2: Specifies to set up only level-2 adjacency on the interface.
Description
Use the isis circuit-level command to configure link adjacency level for an interface of
a level-1-2 router.
Use the undo isis circuit-level command to restore the default.
An interface can establish level-1-2 adjacency by default.
This command is only available on a level-1-2 router. You can use it to configure an
interface to establish the adjacency of a specified level (level-1 or level-2) with the
neighbor, making the interface handle only the specified level hello packets. An
interface can receive and send only one level hello packet on a point-to-point link.
Using this command can reduce the router’s processing time and save bandwidth.
