Been recovering from some plague. Yeah, we use it for qos. I can't think of any other uses for it versus implicit null. Sorry. Been recovering from some plague.

Thanks for sharing !! What are your system specs when running this simulation? Just wondering.. I'm having a bunch of ospf/bgp and ldp flapping when using the a low dead-interval, same thing with bgp.. I suspect my CPU is the culprit not sure yet Awesome! Thanks for sharing !!

Busted. Looks like I had forgot those configs. I updated the post with links to updated configs and .net file. The ebgp stuff doesn't dump a full table because I don't need it. I mainly use it to test outbound announcements, aggregation, etc. Oops. Busted. Looks like I had forgot those configs.
