Manual 6in4 tunneling

This example creates an IPv6 6in4 tunnel, which allows IPv6 hosts in one network to exchange IPv6 data with hosts in another IPv6 network by using the IPv4 tunneling infrastructure. In this example:
  • All IPv6 traffic between hosts in the 3000::/64 and the 4000::/64 networks is tunneled through Switch B and Switch C, respectively.

  • Switch B and Switch C are the manually configured endpoints.

  • IPv6 traffic entering the tunnel endpoints is encapsulated with an IPv4 header based on the 6in4 configuration, and then routed through the IPv4 network using Switch A as the first hop.

  • Static IPv6 routes are used to route into the tunnel interfaces.
