track reachability refresh

Change the refresh interval for tracking the reachability of the next-hop. If the next-hop address in the ARP cache ages out for a route

tracked for its reachability, an attempt is made to check if the next-hop address is reachable after a certain refresh interval before

considering the route DOWN.

Syntax

track reachability refresh interval

Parameters

interval

Enter the refresh interval, in seconds, for object tracking reachability. The range is from 0

to 60 seconds. The default is 60.
