Hello, IPv6 BGP is not supported at this time on that platform and I cannot comment further on a public forum regarding roadmap.  Contact your Cisco Account representative for roadmap information regarding this feature.Steve

Hello,Cisco do not reveal such roadmap detail on public forums.  However, the Security Business Unit is well aware of this request from the field and it is under consideration for a future release.  Steve
