To do… Use the command… Remarks
Enter system view system-view —
Enable the IPv6 packet
forwarding function
ipv6
Required
By default, the IPv6 packet forwarding
function is disabled.
Enter tunnel interface view interface tunnel number —
ipv6 address { ipv6-address
prefix-length |
ipv6-address/prefix-length }
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 or site-local
address is configured for the interface.
Specify the automatic
IPv4-compatible IPv6 tunnel
mode
tunnel-protocol ipv6-ipv4
auto-tunnel
Required
The default tunnel mode is GRE over
IPv4.
The same tunnel mode should be
configured at both ends of the tunnel.
Otherwise, packet delivery will fail.
Configure a source address or
interface for the tunnel source { ip-address |
interface-type interface-number }
Required
By default, no source address or
interface is configured for the tunnel.
NOTE:
•
No destination address needs to be configured for an automatic IPv4-compatible IPv6 tunnel. The
destination address of the tunnel can be automatically obtained through the IPv4 address embedded in
the IPv4-compatible IPv6 address.
• The automatic tunnel interfaces using the same encapsulation protocol cannot share the same source IP
address.
Configuration Example
Network requirements
As shown in Figure 8 , two IPv6 networks are connected to an IPv4 network through Device A and Device
B respectively. Configure an automatic IPv4-compatible IPv6 tunnel between Device A and Device B to
make the two IPv6 networks reachable to each other.
