Has senility set in, or wasn't there even an incident where somebody advertised
127/8 via RIP - and lots of nodes *believed* it, even though they should have
realized that they had an interface on that network already?

(And yes, I know of *multiple* failures of broadcasting a default route and
getting swamped as a result - this one was 127/8 specifically)...
