Step Command Remarks
4. Configure an IPv6
address for the
tunnel interface.
• Configure an IPv6 global unicast
address or a site-local address:
{
ipv6 address { ipv6-address
prefix-length |
ipv6-address/prefix-length }
{
ipv6 address
ipv6-address/prefix-length
eui-64
• Configure an IPv6 link-local
address:
{
ipv6 address auto link-local
{
ipv6 address ipv6-address
link-local
IPv6 link-local address configuration is
optional.
By default:
• No IPv6 global unicast address or
site-local address is configured for the
tunnel interface.
• A link-local address will automatically
be generated when an IPv6 global
unicast address or a site-local
address is configured.
5. Specify the 6to4
tunnel mode.
tunnel-protocol ipv6-ipv4 6to4
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.
6. Configure a source
address or interface
for the tunnel.
source { ip-address | interface-type
interface-number } By default, no source address or
interface is configured for the tunnel.
7. Specify the service
card for forwarding
the traffic on the
interface (in
standalone mode).
service slot slot-number
Optional.
Not specified by default.
8. Return to system
view.

6to4 tunnel configuration example
IMPORTANT:
By default, Ethernet, VLAN, and aggregate interfaces are down. To configure such an interface, bring the
interface up by executing the undo shutdown command.
Network requirements
As shown in Figure 90 , configure a 6to4 tunnel to make Host A and Host B reachable to each other.
