Error description
When there are many routes using the same gateway and if Active DGD is enabled on all of them, this would cause that many ICMP packets to go out to the gateway (one per route with Active DGD flag). This can cause performance issues on the router.
Local fix
Problem summary
Active DGD on multiple routes to same gateway through same interface causes performance issue on the router. When there are many routes using the same gateway and if Active DGD is enabled on all of them, this would cause that many ICMP packets to go out to the gateway (one per route with Active DGD flag). This can cause performance issues on the router.
Problem conclusion
Code is modified to not to send unnecessary ICMP ping requests to the gateway when mulitple routes are configured with same gateway and same interface.
