Configuring an IPv6 over IPv6 tunnel

NOTE:
Only EB and SD cards support configuring IPv4 over IPv6 manual tunnels.

Configuration prerequisites

Configure IP addresses for interfaces (such as the VLAN interface, and loopback interface) on the device
to ensure normal communication. One of the interfaces will be used as the source interface of the tunnel.

Configuration guidelines

Follow these guidelines when you configure an IPv6 over IPv6 tunnel:
To encapsulate and forward IPv6 packets whose destination address does not belong to the subnet
•
where the receiving tunnel interface resides, configure a static route or dynamic routing for
forwarding those packets through this tunnel interface. If you configure a static route to that
destination IPv6 address, specify this tunnel interface as the outbound interface, or the peer tunnel
interface address as the next hop. A similar configuration is required at the other tunnel end. If you
configure dynamic routing at both ends, enable the dynamic routing protocol on both tunnel
interfaces. For the detailed configuration, see Layer 3—IP Routing Configuration Guide.
The IPv6 address of a tunnel interface must not be on the same subnet as the destination address of
•
the tunnel.
The destination address of a route with the tunnel interface as the egress interface must not be on
•
the same subnet as the destination address of the tunnel.
Two or more tunnel interfaces using the same encapsulation protocol must have different source and
•
destination addresses.
• If you specify a source interface instead of a source address for the tunnel, the source address of the
tunnel is the primary IP address of the source interface.

Configuration procedure

Follow these steps to configure an IPv6 over IPv6 tunnel:
To do...
Enter system view
Enable IPv6
Enter tunnel interface view
Configure an
IPv6 address
for the tunnel
Use the command...
system-view
ipv6
Interface tunnel number
ipv6 address { ipv6-address
Configure an
prefix-length |
IPv6 global
ipv6-address/prefix-length }
unicast address
Remarks
—
Required
By default, the IPv6 packet forwarding
function is disabled.
—
Required
Use one of the commands.
