arguably, it's exacerbated the problem of upgrading - the sup2t native line
cards use distributed forwarding while the older cards use centralised
forwarding.  So when it comes time to upgrade due to tcam limitations, you
need to upgrade components on all the line cards too => much more
expensive.  I'm not complaining about this - it's just the cost of higher
performance networking.  But it is an issue that needs to be understood.
