Cisco 7600

I'm aware the Cisco 7600 series is really just an evolution/different way of orienting the chassis of the Catalyst 6500 line. I'm interested in talking to those of you who are doing production tasks in the backbone or core with the 7600, particularly if you've compared it to vendor J or can comment at length on MPLS, VRF, and uRPF features in the device. Please reply off-list. No sales droids please, this is a technical discussion. Tim
