Usage Information
Because the default establishes Level 1 and Level 2 adjacencies, you do not need to configure this command.
Routers in an IS-IS system must be configured as a Level 1-only, Level 1-2, or Level 2-only system.
Only configure interfaces as Level 1 or Level 2 on routers that are between areas (for example, a Level 1-2 router)
to prevent the software from sending unused hello packets and wasting bandwidth.
You can form a Level 1 adjacency if there is at least one common area address between
this system and neighbors. You cannot form Level 2 adjacencies on this interface.
You can form a Level 1 and Level 2 adjacencies when the neighbor is also configured as
Level-1-2 and there is at least one common area, if not, a Level 2 adjacency is established.
This setting is the default.
You can form a Level 2 adjacencies when other Level 2 or Level 1-2 routers and their
interfaces are configured for Level 1-2 or Level 2. Level 1 adjacencies cannot be
established on this interface.
