Both tunnel types are very similar with just ipvv6 differences. Ask a question or join the discussion by visiting ipv6 over ipv4 tunneling Community Forum. Although 6in4 tunnels are generally manually configured, for example the utility AICCU can configure tunnel parameters automatically after retrieving information from a Tunnel Information and Control Protocol TIC server.

Retrieved from ” https: There are similarly named methods, namely 6to4 tuneling 6over4which describe a different mechanism. Send this to a friend Your email Recipient email Send Cancel. Basically it means that we encapsulate IPv6 packets into IPv4 packets or the other way around so that it can be routed. This is how we configure a tunnel interface. Just fixed it, thanks for ipv6 over ipv4 tunneling me know.

How to configure IPv6 tunneling over IPv4

The 6in4 ipf6 has no security features, thus one can easily inject IPv6 packets by spoofing the source IPv4 address of a tunnel endpoint and sending it to the other endpoint. Full Access to our Lessons. This means that the encapsulation overhead is simply the size of the IPv4 header ipv6 over ipv4 tunneling 20 bytes.

A tool such as AICCU can then update the endpoints, in effect making the endpoint dynamic while still using the 6in4 protocol. If you like to keep on ipv6 over ipv4 tunneling, Become a Member Now!

This page was last edited on 13 Novemberat One technique that we can use is tunneling. The 6to4 method makes use of proto too, but instead of static configuration tunmeling the endpoints, the endpoint IPv4 address information is derived from the IPv6 addresses within ipv6 over ipv4 tunneling IPv6 packet header.

The heartbeat protocol signals the other gunneling of the tunnel with its current endpoint location. Pages using RFC magic links. Tunnels of this kind are generally called ‘proto heartbeat’ tunnels.

I could also use physical interfaces but they can ilv6 down. The mentioned packet injection loophole of 6in4 was exploited for a research benefit in a method called IPv6 Tunnel Discovery [3] which allowed the researchers to tunnelnig operating IPv6 tunnels around the world. This will make sure that when a physical interface fails your IGP will try to find another route to the loopback interface of your neighbor.

Explained As Simple As Possible. You can also configure the tunnel interface between the physical interfaces but I like to use loopback interfaces. Three routers are running IPv4. This protocol ipv6 over ipv4 tunneling is ipv6 over ipv4 tunneling designated for IPv6 encapsulation. More Lessons Added Every Week!
