Benefits of IS-IS NSF Awareness

The Integrated IS-IS Nonstop Forwarding Awareness feature allows CPE routers that are NSF-aware to help NSF-capable routers perform nonstop forwarding of packets. The awareness feature is part of the software code; it need not be configured.

The local router is not necessarily performing NSF; its awareness of NSF allows the integrity and accuracy of the RIB and link-state database occurring on the neighboring NSF-capable router to be maintained during the switchover process. Customers would want the IS-IS NSF Awareness feature when their routers are neighbors to NSF-capable routers.
