...reading the host requirements RFC and its definition of the
robustness principle: Why was the behavior above chosen over the
more conceivable and robust "ignore (log) corrupted message, continue
with regular operation" ? Given route flap dampening, dropping the BGP
session is hardly the desirable outcome here. On that note: under
what circumstances should or shouldn't the BGP session come back up
without mnual intervention?
