Hi,

2 default route with different next hop configured on a router,one of them has nqa with low preference.When nqa destination address is unreachable,route changes and backup default route works.

However,when nqa destination address become reachable again,route preemption function is not working.As i see nqa destination ip address does not reply arp request packets (interfaces are up and packets are arriving to desination).What could be the reason ?
