Managing 6in4 and 4in6 Tunnels
In networks where IPv4 and IPv6 operate simultaneously, 6in4 and 4in6 tunnels can be used to enable IPv6/IPv4
hosts to reach services using the opposite protocol. IPv6/IPv4 hosts and networks isolated from one another can
also use these tunnels to access one another.
In a 6in4 tunnel, IPv6 traffic is encapsulated over configured IPv4 links, and vice versa for 4in6 tunnels.
NOTE
For information about how to monitor traffic through the tunnel, refer to
Statistics for Routable
