6to4. 6to4 is a transition mechanism for migrating from IPv4 to IPv6. It allows two systems using IPv6 to communicate if their traffic has to transverse an IPv4 network.

Jacob is a network engineer and needs to ensure that each critical network device that is configured with an IPv6 address can communicate with other devices using IPv6 addresses, even if their traffic has to transverse IPv4 networks. Which of the following best describes what Jacob should configure for this need? - IPv4 forwarding - 6to4 - IPv6 routing - IP submasking - IPv6 routing - IP submasking
