I have found that for experimental purposes, all current (and not-so-current)
Cisco gear can do dual stack without any big problems. If you need multicast,
make sure you have the right feature set (and you'll probably not want to try
that on an ASR 7401 - anybody remember that one? ;-) ).

If you need some real-life forwarding performance, you may want to consider
6500/7600, ASR1k, ASR9k or the Layer 3 switches (3560, 3750, probably Nexus).

If you want good BGP performance, I would - depending on your forwarding
needs - recommend 7201/7301 (software forwarding, slow), ASR1k, ASR9k,
or a 65/76 with this latest super-fast supervisor board (RSP-whatever).

I bet you could also go for CRS's or 12Ks...

I have, for the future, settled for ASR1k for our needs in peering and
autonomous nodes, and we're using 65/76 with SUP720-3BXL in the core.

We don't have crazy traffic levels, though ;)

Cheers,
