New IP version 6 compatability

What is needed to say Cisco router 3745 or switch 4507R is IPv6 compatable? The IOS version, or firmware version?

The IOS version decides on the IPv6 compatibility. When you download the IOS you can choose the IOS that will be compatible with Ipv6 addressing.

You might find Cisco Feature Navigator useful for this sort of question. www.cisco.com/go/fn

From there, one can navigate down and determine that, for the 3750, Cisco recommends IOS 12.2(25) variants and, for the 4507R, IOS 12.2(20) or 12.2(25) variants are recommended for IPv6 feature support.
