We run mostly on 7200s. 12.3 definitely still has some bugs. Esp.
with odd things like directly connected routes and networks
disappearing from the routing table when using CEF - at least until
you globally disable and re-enable CEF. However, there are some
scenarios where we have to use the 12.3 train. We run 12.2(20
something) wherever possible. We have some customers running super
new gear with 12.4T. Craziness I say! I'm not directly involved with
those clients at all, but I certainly wouldn't want to run that in
production yet. :)
