Or, protect your existing investment in 6500 and replace the SUP720 with the
SUP2T. You can then deploy the WS-X6904-40G-XL blades which give you 4 * 40G
or 16 * 10G on a 80G backplane (i.e. 2:1 oversubscription). I'm in the process
of going through this upgrade at the moment and I'm happy with what I'm seeing.

A lot depends on the total traffic throughput you're looking to switch/route.

You can then look to migrate onto the 6880 chassis which gives you a faster
backplane, whilst retaining compatibility with existing linecards.
