View Level 1 Area Information

Use the following procedure to display Level 1 area information. IS-IS provides support for hierarchical routing, which enables you to partition large routing domains into smaller areas. IS-IS uses a two-level hierarchy, dividing the domain into multiple Level 1 areas and one Level 2 area. The Level 2 area serves as backbone of the domain, connecting to all the Level 1 areas.
