You redistribute a full Internet routing table without any filtering into
your IGP and right after you type the redistribute command you'll say "hey
what happened to my router?". Then a couple minutes later you'll be saying
"hey what happened to my job?" 8)
But if you're working in a lab environment I say redistribute away!
