Managing Area Tags 413
Section 5.18.4
Managing Area Tags
An IS-IS area is a grouping of inter-connected (or neighboring) IS-IS configured routers. As opposed to OSPF,
where an Area Border Router (ABR) can exist in two areas at once, IS-IS routers reside only in one area. It is the
link between routers in two different areas that forms the border. This is because an IS-IS router has only one
Network Service Access Point (NSAP) address.
A single router can be configured to act as a Level-1, Level-2 or Level-1-2 router in one or more areas.
Routers are associated with areas by area tags, which define the routing type, metric, and authentication/
authorization rules.
The following sections describe how to configure and manage area tags for IS-IS:
•
Section 5.18.4.1, “Viewing a List of Area Tags”
• Section 5.18.4.2, “Adding an Area Tag”
• Section 5.18.4.3, “Deleting an Area Tag”
