For a Level-1 (Level-2) router, the circuit level can only be Level-1 (Level-2). For a Level-1-2 router, you must
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.
