Usage Information
The IS-IS protocol automatically determines area boundaries and are able to keep Level 1 and Level 2 routing
separate. Poorly planned use of this feature may cause configuration errors, such as accidental area partitioning.
If you are configuring only one area in your network, you do not need to run both Level 1 and Level 2 routing
algorithms. You can configure the IS type as Level 1.
