Cisco has supported IPv6 since 2001... you should be good. The 2900 line came out like 2-3 years ago, not sure about the 3560, but after 2001 I would think.

If you want to verify you software release level, do a "show version" and just make sure it's higher than 12.0

Please check you router with IPV6 enable .

To enable routing of IPv6 packets – required to enable IPv6 on a router:
Router(config)# ipv6 unicast-routing

To enable IPv6 on an interface:
Router(config-if)# ipv6 enable

To add an IPv6 address to an interface:
ipv6 address <address>/<prefix> [link-local] [eui-64]

To leave the interface unnumbered:
ipv6 unnumbered eth 0/0

If these command will not owrk then upgrade IOS of the router .
