OK, Mike. Maybe you're on to something, but...
there's only basically one command, ip irdp.
Using that one command, how do I make R5 generate irdp messages as opposed
to just listening for those messages. And, likewise with the 3550, how do I
make the 3550 listen for irdp instead of sending them?
Thanks, Tim
