[PLUG] Non-linux loobpack weirdness, does not responds

RFC 3330 states: - This block is assigned for use as the Internet host
loopback address. A datagram sent by a higher level protocol to an
address anywhere within this block should loop back inside the host.
This is ordinarily implemented using only for loopback,
but no addresses within this block should ever appear on any network
anywhere [RFC1700, page 5].
On a Linux machine, pinging will reach the localhost host and respond.  On a Solaris 9 and AIX machine this does not happen.  The Solaris 9 routing table had a bad entry,              UH        5 725905  lo0
I added              U         1      0  lo0
, but that didn't fix the problem.  I am about at add to lo0 to see if that makes a difference.  Does anyone have a similar experience?   Many years ago I worked on Solaris machines and remember doing something for the loopback but I can't remember what and Google searches haven't turned up what I am looking for.
