I've got seven 2500-series routers in my lab and one 2610. None of the 2500's have IOS images capable of routing IPv6 so I scanned the eBay and found some <$200 2509 routers with IOS12.3 onboard. Except then I remembered I want to get hands-on experience with MPLS, which none of the 2500's are capable of. So if I'm going to drop $200 on yet another router for my lab, it may as well be MPLS-capable.
But I know there's only certain 2600-series models that have that capability. Can anyone tell me specifically which ones? Are there any routers in the 1700 series that can do both MPLS and IPv6 as well?
