•
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.
•
Only the IPv6 over IPv6 tunnel has a limit on the maximum number of nested encapsulations of a
packet.
Configuration procedure
To configure an IPv6 over IPv6 tunnel:
Step
Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enable IPv6.
ipv6
By default, the IPv6 packet forwarding
function is disabled.
3.
Enter tunnel interface
view.
Interface tunnel
number
N/A
4.
Configure an IPv6
address for the tunnel
interface.
•
(Approach 1) Configure an IPv6
global unicast address or
site-local address:
{
ipv6 address
{
ipv6-address
prefix-length
|
ipv6-address
/
prefix-length
}
{
ipv6 address
ipv6-address
/
prefix-length
eui-64
•
(Approach 2) Configure an IPv6
link-local address:
{
ipv6 address auto link-local
{
ipv6 address
ipv6-address
link-local
Use either approach.
By default, no IPv6 address is
configured for the tunnel interface.
5.
Specify the IPv6 over
IPv6 tunnel mode.
tunnel-protocol
ipv6-ipv6
IPv4 over IPv4 tunnel by default.
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 interface.
source
{
ipv6-address
|
interface-type interface-number
}
By default, no source address or
interface is configured for the tunnel.
7.
Configure the
destination address for
the tunnel interface.
destination
ipv6-address
By default, no destination address is
configured for the tunnel.
