Configuring the Device Level

Configuring the Device Level

Context

Configure the device level according to network planning requirements:
  • When the level of a device is Level-1, the device establishes neighbor relationships with only Level-1 and Level-1-2 routers in the same area and maintains only Level-1 LSDBs.
  • When the level of a device is Level-2, the device can establish neighbor relationship with Level-2 routers in the same area or different areas and with Level-1-2 routers in different areas and maintain only Level-2 LSDB.
  • When the level of a device is Level-1-2, the device can establish neighbor relationships with Level-1 and Level-2 routers and maintain Level-1 and Level-2 LSDBs.
If the levels of IS-IS devices are changed during network operation, the IS-IS process will be restarted and IS-IS neighbor relationships will be disconnected. Setting the levels of devices when configuring IS-IS is recommended.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run isis [ process-id ]

    The IS-IS process view is displayed.

  3. Run is-level { level-1 | level-1-2 | level-2 }

    The level of the switch is configured.

    By default, the level of the switch is Level-1-2.
