More over, a boot parameter to tweak it is absolutely not needed

sysctl -w net.ipv6.route.max_size=16384

or

echo 16384 >/proc/sys/net/ipv6/route/max_size

IPv4 has to allocate a hash table at boot time, and this hash table is
not resized. Thus some really special purpose machines need a boot
param.
