You want to use MBGP to carry IPv6 routing information between autonomous systems.
MBGP readily carries IPv6 unicast routing information between IPv6 BGP peers:
Router1#configure terminalEnter configuration commands, one per line. End with CNTL/Z. Router1(config)#router bgpRouter1(config-router)#65520no bgp default ipv4-unicastRouter1(config-router)#neighborAAAA:5::2remote-asRouter1(config-router)#65522neighborAAAA:5::AA9remote-asRouter1(config-router)#65521address-family ipv6Router1(config-router-af)#neighborAAAA:5::2activateRouter1(config-router-af)#neighborAAAA:5::AA9activateRouter1(config-router-af)#networkRouter1(config-router-af)#AAAA:2222::2/64no synchronizationRouter1(config-router-af)#exit-address-familyRouter1(config-router)#exitRouter1(config)#endRouter1#
And you can even run a combination of IPv4 and IPv6 BGP on the same router:
Router9#configure terminalEnter configuration commands, one per line. End with CNTL/Z. Router9(config)#router bgpRouter9(config-router)#65521no bgp default ipv4-unicastRouter9(config-router)#neighborAAAA:5::1remote-asRouter9(config-router)#65520neighbor192.168.1.103remote-asRouter9(config-router)#65525address-family ipv4Router9(config-router-af)#redistribute connectedRouter9(config-router-af)#neighbor192.168.1.103activateRouter9(config-router-af)#no auto-summaryRouter9(config-router-af)#no synchronizationRouter9(config-router-af)#exit-address-familyRouter9(config-router)# ...
