(ASCEND) 1800's and how hard they blow
So we're not the only ones. We run nothing but isdn on our
1800's -- no boards in the slots. They run RipV2.
* They frequently don't sync on the BRI lines when rebooted.
* Some connections lose routes spontaneously -- the connection
stays up but no packets are passed. The route disappears from
the routing table.
* Some connections experience significant packet loss (while
others run fine). The routers have to be rebooted to correct it.
* We have problems raising a second channel for some connections.
Dropping the connection often fixes the problem... temporarily.
* These problems occur several times a week. Turn stacking on
and they manifest themselves several times a day (though we
occasionally had up to 3 trouble-free days).
Yes, we have reported the problems (time and time again). There
are open trouble tickets that date back nearly a year (and the
problems have existed much longer). The eternal recommendation is
to try the latest release and see if it fixes anything (it usually
doesn't and generally breaks something new).
Ascend has pointed out to us that although the Max has a lot of
features, we shouldn't expect to actually be able to use them in
any particular combinations. With no extra plug-in boards, just
the basic built-in interfaces, and a single routing protocol -- it
IS a router after all -- you'd expect it to work fairly well.
It doesn't.
I see that some people find them satisfactory. Please buy ours
when you want to add capacity. I recommend the Cisco 3640.
