White Paper Abstract:
This white paper describes that currently Group Domain of Interpretation (GDOI) encryption is not supported for direct IPv6 data traffic. However, you can use GDOI encryption on IPv6 packets by applying the cryptography map on the physical interface with an IPv4 address and using IPv6 tunnels between the group members. IPv6 tunnels can be either 6to4 tunnels or multipoint generic routing encapsulation (mGRE) dynamic multipoint VPN (DMVPN) tunnels.
