When you say "MPLS" can you be more specific? L3VPN? EoMPLS? VPLS?
towards an ASR 9000, but then as we need Layer 2 services, I'm swayed back to the 6500E's. They'll be used for both aggregation and direct access.
I don't know the ASR9k at all, so can't comment on that. People speak well of them though.
I have been pondering the Nexus 7K's looking towards the future and 100G coming onto our network, but they lack the MPLS support at the moment.
Likewise. We're watching N7k MPLS with a keen eye. Didn't cisco recently announce the phase1 (layer 3) stuff?
Is a 6500 still the best bang for your buck or does the lack of anything over 10G ports hold it back?
Talk to your cisco account manager about sup2T. It's supposed to be out shortly, and offers a fair (not brilliant) improvement in 10g densities on the 6500 platform, as well as 40G and 100G roadmap and a bunch of incremental improvements (better netflow, vpls, IPv6 uRPF, faster CPUs)
Other platforms may still be better; but sup720 is very shortly going to be "2nd tier" 6500 I suspect, so I'd compare something new with something new(ish). Of course it'll be brand new and riddled with bugs, so...
FWIF we use a smattering of 10g on our sup720 platforms with the 6716 cards; it's currently a pricey 10g platform :o(
