Hello Nick, Playing with OSPF hello/dead timers is possible but not the best approach. If you need fast dead peer detection, BFD is much better option. It uses less CPU and allows much better detection time than OSPF timers.

It's quite usual these days to use a much shorter hello and dead interval than 10/40 seconds. I usually use hello=1 and dead=4 seconds for everything these days.
