The number of nexthop buckets in a resilient nexthop group never changes, so when the gateway address of a nexthop cannot be resolved, the nexthop buckets are programmed to trap packets to the CPU in order to trigger resolution. For example: # ip nexthop add id 1 via 198.51.100.1 dev swp3 # ip nexthop add id 10 group 1 type resilient buckets 32 # ip nexthop bucket get id 10 index 0 id 10 index 0 idle_time 1.44 nhid 1 trap Where 198.51.100.1 is a made-up IP. Test that in this case packets are indeed trapped to the CPU via the unresolved neigh trap.
