Implementing IS-IS

To implement IS-IS:

  1. Enable IS-IS on the intermediate point.
  2. Enable IS-S on each interface that will use IS-IS routing to initiate the forming of an adjacency with the IS-IS neighbor.
  3. Configure a NET for each area (up to three) the router will route to using IS-IS.
  4. Optionally, modify IS-IS optional global parameters.
  5. Optionally, modify IS-IS optional interface parameters.
