Re: sell shell accounts?

Karl,

We have been running NetStars in the vBNS for ~1 year. While the
h/w is impressive, the GigaRouter s/w still aspires to the level
of Cisco's. And no, I don't mean gated. As to your comment
"(presuming the BGP issues get completely resolved)."--we have
yet to take full routing in our production routers, but we are
close. We have had some problems with the RMS (486 running BSDI &
gated) being able to distrubute the forwarding table to the 
GigaRouter linecards (FDDI, ATM/OC-3c, & HiPPI) during start-up.
New s/w addresses this pacing issue, and we expect to deploy
BGP on our GigaRouters very soon. OSPF works very well on these
boxes, and considering that when the NetStars were first deployed
everything was static, we have made some progress :) Also, we
look forward to getting our hands on some ATM/OC-12c cards this
fall.

The NetStar is an interesting router that has made a lot of progress,
and I hope they stay in the race. 

						Regards,
						Randy
