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.

is-level.

# Suppose serial 2/0 is connected to a non backbone router in the same area. 
Configure the link adjacency level of serial 2/0 as Level-1 to prevent sending and 
receiving Level-2 Hello packets.

p2p: Specifies the interface’s network type as P2P.

Use the isis circuit-type command to configure the network type for an 
interface.

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

By default, the network type of a router’s interface depends on the physical media.
