The IS-IS area address defines an L1 or L2 area within an AS. An IS-IS routing process must be assigned at least one area address before it can send or process PDUs. The area address must be configured appropriately. Level 1 routers only form adjacencies with other level 1 routers with at least one area address in common. Multiple area addresses may be configured, which may be desirable during a topological transition. The maximum number of area addresses that can be configured is 3.
The following command assigns area address 0011.03 to areax:
configure isis area areax add area-address 0011.03
