Next up the road are the 6800's.
Essentially SUP-2T's, so you get software parity Day One,
but still the same supervisor module.
We are running 6880's (which are the fixed SUP-2T's, but
with modular line cards), but only a core switching (Layer 2
Ethernet) role. Great port density since the 10Gbps ports
are now SFP+, but oversubscribed line cards 2:1, since each
slot is 80Gbps, but the line card comes with 16x 10Gbps
ports. You can disable oversubscription and go into
performance mode, which disables half the ports on the line
card - we do that.
IP-/MPLS-wise, whatever you can do on the 6500 you can do on
the 6800, but I can't say for sure as we're running them as
That said, if your goal is IP, just consider the ASR9000,
MX, and whatever else other vendors can do in this space.
