2: System level 

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.  

Use the isis circuit-level command to set the circuit level for the interface.  

Use the undo isis circuit-level command to restore the default.  

An interface can establish either the Level-1 or Level-2 adjacency by default.  

Note that:  

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.  

Related commands: is-level.  

# 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.
