Delaying Removal of Access Routes and Access-Internal Routes After Graceful Routing Engine Switchover

 

In subscriber networks configured with either nonstop active routing (NSR) or graceful restart, you can configure the router to delay for 180 seconds (3 minutes) before removing access routes and access-internal routes for DHCP and PPP subscriber management after a graceful Routing Engine switchover takes place.

To configure the router to delay removal (flushing) of access-routes and access-internal routes after a graceful Routing Engine switchover:

  1. Specify that you want to configure subscriber management.
  2. Configure the router to wait 180 seconds before removing access-routes and access-internal routes after a graceful Routing Engine switchover.
