Configuring a 6to4 Tunnel
Configuration Prerequisites
z
Configure IP addresses for interfaces (such as the VLAN interface, and loopback interface) on the
device to ensure normal communication.
z
Specify one of the above interfaces as the source interface of the tunnel.
z
Ensure reachability between the tunnel source and destination addresses.
Configuration Procedure
Follow these steps to configure a 6to4 tunnel:
To do…
Use the command…
Remarks
Enter system view

—
Enable IPv6
ipv6
Required
By default, the IPv6 packet forwarding
function is disabled.
Enter tunnel interface view

}
Configure an
IPv6 global
unicast
address or a
site-local
address
ipv6 address
ipv6-address/prefix-length
eui-64
Required.
Use either command.
By default, no IPv6 global unicast
address or site-local address is
configured for the tunnel interface.
ipv6 address auto link-local
Configure an
IPv6 address
for the tunnel
interface
Configure an
IPv6 link-local
address
ipv6 address
ipv6-address
link-local
Optional
By default, a link-local address will
automatically be generated when an
IPv6 global unicast address or site-local
address is configured.
Specify the 6to4 tunnel mode
tunnel-protocol ipv6-ipv4 6to4
Required
By default, the tunnel is a GRE over
IPv4 tunnel. The same tunnel mode
should be configured at both ends of the
tunnel. Otherwise, packet delivery will
fail.
