View Level 1 Remote Area Information
About this task
Perform this procedure to display Level 1 remote area information. Remote Intermediate-System-to-Intermediate-System (IS-IS) provides support for hierarchical routing, which enables the system to partition large routing domains into smaller areas. Remote 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.
Important
The IEEE 802.1aq standard currently only defines the use of one hierarchy, Level 1. Level 2 function is disabled.
Procedure
- In the navigation pane, expand the folders.
- Select IS-IS Remote.
- Select the L1 Area tab.
