Which of the following solutions will encapsulate IPv6 packets with IPv4 headers？（）
- ACreate an IPv4 tunnel and assign the tunnel IPv6 addresses
- BCreate IPv4 interfaces on both ends of the network， and use either static routes or a routingprocess to direct IPv6 packets through those interfaces
- CIPv6 packets cannot be encapsulated with IPv4 headers because the addresses are notcompatible
- DCreate IFV6 interfaces on both ends of the network， and use static routes to point the IPv4address to those interfaces
- EUse an IPv6 routing protocol like OSPFv3 and assign IPv4 packets to that process
- FCreate an IPv4 tunnel and use the tunnel mode ipv6ip command
