QUESTION
What happens when an IPv6 enabled router running 6to4 must send a packet to a remote destination and the next hop is the address of 2002::/16?

A. The IPv6 packet has its header removed and replaced with an IPv4 header
B. The IPv6 packet is encapsulated in an IPv4 packet using an IPv4 protocol type of 41
C. The IPv6 packet is dropped because that destination is unable to route IPv6 packets
