Ive had a few customers on a small scale routers perfectly, I believe the dead time in Cisco default is 4 times the hello. I have all of them set of 3 sec Hello packets and a 30 second heal time and zero route instabitliey. But I have zero experience with the sup32/6509 kit.
This has been done on 2600/2800 3700/3800 routers with no issues.
