By default, if "ping" is configured for a route, and the ping to the next hop gateway fails, then the route is deleted from routing table. The moment the ping to the next hop gateway succeeds, the route is added back to the routing table.

However, RouteD daemon on Standby cluster member incorrectly keeps count of the failed pings.
