    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 .
