Attached is a set of ICMP re-direct messages that my host (TYCHO 10.0.0.126)
received this morning.  The packets were being sent to BBNCC-COLUMBIA.ARPA
(8.1.0.35) and were being sent thru the BBNNET2-ARPANET-GW (10.7.0.63,
8.3.0.9).  The following round-the-world tour is the result.  Do any of
the gateway gurus have any words of wisdom on this?  It seems awfully
strange from where I sit!  Why the hops to the MILNET and why the loops
in the West Coast gateways?
