	Yet another network problem (this time at MIT) has been traced
to hosts (Symbolics lisp machines) not understanding subnet broadcast
packets and forwarding them (and sending ICMP Redirects as well). To repeat:
a) under no circumstances should hosts forward packets, and b) when using
broadcast, try and use the simplest possible broadcast address (all 1's)
to prevent misunderrstanding of whether or not something is a broadcast.
