Example for Configuring a Manual IPv6 over IPv4 Tunnel
This section provides an example for configuring a manual IPv6 over IPv4 tunnel.
Networking Requirements
As shown in Figure 6-1, two IPv6 networks are connected to Device B on the IPv4 backbone network through Device A and Device C. To interconnect the two IPv6 networks, configure a manual IPv6 over IPv4 tunnel between Device A and Device C.
Precautions
When configuring a manual IPv6 over IPv4 tunnel, note the following points:
Create a tunnel interface and set parameters for the tunnel interface.
Perform the following configuration on both Device A and Device C. The source IPv4 address of the local end is the destination IPv4 address of the remote end of the tunnel. Similarly, the destination IPv4 address of the local end is the source IPv4 address of the remote end.
Configure an IPv6 address for the tunnel interface to support routing protocols.
Configuration Roadmap
The configuration roadmap is as follows:
Assign an IP address to each physical interface.
Configure the IPv6 address, source IPv4 address, and destination IPv4 address for the tunnel interface.
Set the protocol type to IPv6-IPv4.
Data Preparation
To complete the configuration, you need the following data:
IP addresses of interfaces
IPv6 address, source IPv4 address, and destination IPv4 address for the tunnel interface
