6to4 tunneling supports which type of routing?

Only static routing.
Static and BGPv4 routing.
Only dynamic routing.
OSPF routing only.

The correct answer is: Static and BGPv4 routing.

6to4 tunneling is a method that facilitates the transmission of IPv6 packets over an IPv4 network. It relies on the encapsulation of IPv6 packets within IPv4 packets, allowing for interoperability between the two protocols. The correct answer emphasizes that 6to4 tunneling supports both static routing and BGPv4 (Border Gateway Protocol version 4) routing. Static routing is commonly used in simple or small networks where routing paths do not frequently change. BGP, on the other hand, is a dynamic routing protocol suited for larger and more complex networks, especially those involving multiple paths or internet exchanges. The fact that 6to4 can work with BGP allows for the dynamic learning of routes and better scalability in multi-homed environments and interdomain routing scenarios, making it more versatile compared to supporting only static routing. Dynamic routing protocols like BGP enable routers to adapt to changes in the network, providing greater reliability and efficiency when implementing 6to4 tunneling in diverse network architectures. This compatibility with both routing types enhances the protocol's functionality and application in different environments.
