[c-nsp] Searching for cheap IPv6 NAT-PT Cisco-device

[Tóth András]

According to the Feature Navigator (which we know is not always
accurate), IPv6 is supported in IPBASE only on 7200 and 7300 routers
and Catalyst 3560/3750, CBS3k blade switches and 6500 Sup32 switches.

On 2811 routers with 12.4T, IPv6 is available in IP Voice, SP
Services, Advanced IP Services, Enterprise Services and Advanced
Enterprise Services.

The smaller reasonable device to play with would be Cisco 1841 but it's also available on 870 and 880 platform. Of course for the production network I'd check how much traffic it's going to handle (and not only in number of TCP sessions that have to be translated but throughput itself, because NAT64 is process switched since 12.4(20)T, until that it was fast switched).
