IPv6 over IPv4 Tunnel

Overview of IPv6 over IPv4 tunnel

The IPv6 over IPv4 tunnel is applied to IPv4 networks to connect IPv6 islands (also called isolated IPv6 domains).

Understanding IPv6 over IPv4 tunnel

IPv6 over IPv4 tunneling encapsulates each IPv6 packet with an IPv4 header so that the encapsulated IPv6 packet traverses the IPv4 network. In this way, isolated IPv6 networks can securely communicate with each other.

Limitations and Precautions for IPv6 over IPv4 tunnel

Configuring an IPv6 over IPv4 Tunnel Using the CLI

IPv6 over IPv4 tunnels are categorized into manual tunnels, GRE tunnels, automatic tunnels, 6to4 tunnels, 6RD tunnels, and ISATAP tunnels.

Maintaining IPv6 over IPv4 Tunnel

After configuring the IPv6 over IPv4 tunnel, you can run the display commands in any view to display and verify the configurations.

Configuration Examples for IPv6 over IPv4 tunnel

This section provides examples for interconnecting IPv6 networks over IPv4 networks through various tunnel modes based on varied networks and security requirements.
