Description

Configures the type of adjacency desired for the specified interface. The no version resets the circuit type to level 1 and level 2.

Options

• level-1—Establishes a level 1 adjacency if there is at least one area address in common between this router and its neighbors
• level-1-2—(default) Establishes a level 1 and 2 adjacency if the neighbor is also configured as a level 1-2 router and there is at least one area in common. If there is no area in common, a level 2 adjacency is established.
