Subject: Re: traceroute/ping from agate-vbns to jsimpson-h.gsfc.nasa.gov
Looks like we need to get agate to aim its packets for j-simpson-h out its
ATM interface for a start. Then our border router, tc0.router.umn.edu, has
as its only route to jsimpson-h.gsfc.nasa.gov one learnt from
aads.vbns.net. With the VPs set up now we should be able to get a route
from the NREN Chicago router, right? David, are you announcing
169.154.0.0/16 to us?
