The three IPv6 tunneling methods that are point-to-multipoint in nature are:
This method encapsulates IPv6 packets inside IPv4 packets and sends them over an IPv4 network. It is a point-to-multipoint tunneling protocol that allows multiple IPv6 hosts to communicate over a shared IPv4 network using a single tunnel endpoint. In this method, the IPv6 packet is encapsulated in an IPv4 packet with the protocol number 47. The IPv4 header contains the source and destination IPv4 addresses of the tunnel endpoints.
This method is used to connect IPv6 hosts over an IPv4 network without the need for explicit tunnel configuration. It uses the IPv4 address of the tunnel endpoint to automatically configure the IPv6 addresses of the hosts. It is also a point-to-multipoint tunneling protocol that allows multiple IPv6 hosts to communicate over a shared IPv4 network using a single tunnel endpoint.
This method involves the manual configuration of the tunnel endpoints and the tunneling protocol. It allows multiple IPv6 hosts to communicate over a shared IPv4 network using a single tunnel endpoint. It is also a point-to-multipoint tunneling protocol.
The other two options, Automatic 6to4 and Automatic IPv4-compatible, are not point-to-multipoint tunneling protocols. Automatic 6to4 is a point-to-point tunneling protocol that allows IPv6 hosts to communicate over an IPv4 network without the need for explicit tunnel configuration. Automatic IPv4-compatible is a transition mechanism that allows IPv6 hosts to communicate with IPv4 hosts over an IPv6 network. It is not a tunneling protocol.
