Which of the following solutions will encapsulate IPv6 packets with IPv4 headers？（）

• A、Create an IPv4 tunnel and assign the tunnel IPv6 addresses
• B、Create IPv4 interfaces on both ends of the network， and use either static routes or a routingprocess to direct IPv6 packets through those interfaces
• C、IPv6 packets cannot be encapsulated with IPv4 headers because the addresses are notcompatible
• D、Create IFV6 interfaces on both ends of the network， and use static routes to point the IPv4address to those interfaces
• E、Use an IPv6 routing protocol like OSPFv3 and assign IPv4 packets to that process
• F、Create an IPv4 tunnel and use the tunnel mode ipv6ip command
