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.
