ISATAP tunneling

E.
PPP tunneling

F.
Teredo tunneling

Explanation:
Below is a summary of IPv6 transition technologies:
6 to 4 tunneling: This mechanism allows IPv6 sites to communicate with each other over
the IPv4 network without explicit tunnel setup. Themain advantage of this technology is that
it requires no end-node reconfiguration and minimalrouter configuration but it is not
intended as a permanent solution.
ISATAP tunneling(Intra-Site Automatic Tunnel Addressing Protocol):is a mechanism for
transmitting IPv6 packets over IPv4 network. The word “automatic” means that once an
ISATAP server/router has been set up, only the clients must be configured to connect to it.
Teredo tunneling:This mechanism tunnels IPv6 datagrams within IPv4 UDP datagrams,
allowing private IPv4 address and IPv4 NAT traversal to be used.
In fact, GRE tunneling is also a IPv6 transition mechanism but is not mentioned in ROUTE
so we shouldn’t choose it (there are 4 types of IPv6 transition mechanisms mentioned in
ROUTE; they are: manual, 6-to-4, Teredo and ISATAP).
