Re: Custom Queuing

My teeth don't feel longer. But yes, indeed... the queue 0 is used for
many layer2 keepalives as well as routing protocol hellos/updates.

Specifically IS-IS, EIGRP and OSPF use it for sure. I haven't found
anything telling me whether BGP did or not, and I don't recall ever
caring to do debugs on it to be sure, so I wouldn't count on that one.

Perhaps someone whose teeth FEEL longer may remember something more on
that (grin). RIP does not make that list, by the way. *shrug*
