community-list in route-map on ipv6 BGP session

Hi folks,

We use 'ip community-list' to define community filters that we then apply in route-maps applied to BGP neighbours.

If we apply the same route-map to IPv6 neighbors all routes are filtered, rather than just those not matching the community. There doesn't seem to be an 'ipv6 community-list' command nor anywhere we can make either the route-map or the community-list ipv6 specific. I'd assume the community-list is v4 only and as such when applied to a v6 peer, there are no matches.

Does anyone know how we can create an ipv6 community-list or use the existing community-lists in a route-map in a way that will work for a IPv6 neighbour? There's no difference in the communities between ipv4 and ipv6 and ideally we'll re-use the same route-map too as that has nothing version specific in it.

Any help greatly appreciated.

Thanks

Simon
