It's all well and good that everyone knows backwards and forwards how to
configure this sort of thing on a Cisco, but there are other vendors out
there making routers too.  What is trivial in IOS may turn out to be a
real bitch on other equipment.  From what I understand, Bay is working on
getting a similar feature in 12.something, but what of Ascend, OpenRoute,
and others making equipment that can handle big connections?

Perhaps some of the folks on NANOG that use equipment other than Cisco
would like to share how they "configure their router for that"?  It would
be a nice service to everyone...
