configure isis area add area-address

configure isis area area_name add area-address area_address


This command adds an IS-IS area address to the specified routing process.

Syntax Description

area_name Specifies the area name of the IS-IS process to which to add the area address.
area_address Specifies an IS-IS area address to add to the IS-IS process. The area address can be from 1 to 13 bytes long and must be entered in the following format: 0101.0102.0103.0104.0105.0106.07.



Usage Guidelines

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
