Default level
2: System level
Parameters
level-1: Sets the circuit level to Level-1.
level-1-2: Sets the circuit level to Level-1-2.
level-2: Sets the circuit level to Level-2.
Description
Use isis circuit-level to set the circuit level for the interface.
Use undo isis circuit-level to restore the default.
An interface can establish either the Level-1 or Level-2 adjacency by default.
For a Level-1 (Level-2) router, the circuit level can only be Level-1 (Level-2). For a Level-1-2 router,
you need to specify a circuit level for a specific interface to form only the specified level neighbor
relationship.

Examples
# VLAN-interface 10 is connected to a non backbone router in the same area. Configure the circuit
level of VLAN-interface 10 as Level-1 to prevent sending and receiving Level-2 Hello packets.
