Description

aborrero@cloudnet1005:~ $ sudo ip netns exec qrouter-d93771ba-2711-4f88-804a-8df6fd03978a ip neigh show | wc -l

aborrero@cloudnet1005:~ $ sudo sysctl -a | grep gc_thresh | grep neigh
net.ipv4.neigh.default.gc_thresh1 = 1024
net.ipv4.neigh.default.gc_thresh2 = 2048
net.ipv4.neigh.default.gc_thresh3 = 4096
net.ipv6.neigh.default.gc_thresh1 = 128
net.ipv6.neigh.default.gc_thresh2 = 512
net.ipv6.neigh.default.gc_thresh3 = 1024

This is not an urgent issue today (no overflows) but constant evictions from the neighbor table feels unnecessary and non optimal.
