Basic IPv4 functionality (i.e. BGP, OSPF, netflow, acl) is
rock solid on this platform. There are some horrible IOS
bugs but the only ones that have caused us issues is when
we've tried something more "adventurous". Haven't used 65xx
in an MPLS environment or with v6, or NSF, or SSO etc etc and
I'm sure there's issues down those lines. But, for basic
routing/switching, it's a great platform.
We're running into some hideous bugs at the moment. Mostly memory leaks and
such. We've had to reboot our box twice now in two weeks, and are making the
upgrade to 12.2(18)SXD3 from SXD2 on Friday in the hopes of some resolution.
Unfortunately both times we've not been able to get to the console or telnet
to the box with the aim of getting some debugging out of it so I'm going to
have a hard time getting anything from the TAC. :-(
Only running basic L3 VPNs, with OSPF for the VRF routing protocol, and a
lot of straight internet connections, nothing particularly fancy.
Cheers,
Chris.
