We had temporarily switched over to the new EGP gateway and noticed that
the gateways couldn't make up their mind as to who was handling a
particular network. For example, all ARPANET traffic would oscillate
between MCLEAN-MB.DDN.MIL and CAMBRIDGE-MB.DDN.MIL with the gateways
redirecting to each other. This doesn't seem very productive. We have
since then switched back to the older gateways which seem to work ok.
Hopefully, this will be fixed before the mandatory switchover later on
this month.

Can you please tell us when this happened, or whether it still goes on? If it
is the current version, then there may be some configuration problem. If it
was a previous version, you may have been bitten by a transition between
versions, or an old load-sharing table.
Was this problem noted at the host you sent mail from, that is, 26.0.0.18
radc-multics.arpa?
Can you tell whether the redirects you received were the subtype 'net' or
subtype 'host'? Would your host act differently based on this distinction?
In general, if you find such a 'smoking gun' type of problem, this one or
another, please call the NOC, 800-492-4992, and be prepared to report times
and explicit addresses. Any other detail, such as your local routing table,
may be useful also. If you wish to report via email, I suggest you use the
mailing list 'gw-fire@bbn.com'.
