Configuration Procedure; Configuration Example - HP A7500 Series Configuration Manual

destination IPv4 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.
• 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 IPv4 over IPv6 manual tunnel:
To do...
Enter system view
Enable IPv6
Enter tunnel interface view
Configure an IPv4 address for
the tunnel interface
Specify the IPv4 over IPv6
manual tunnel mode
Configure the source address
or interface for the tunnel
interface
Configure the destination
address for the tunnel
interface

Configuration example

Network requirements
As shown in
Configure an IPv4 over IPv6 manual tunnel between Switch A and Switch B to make the two subnets
reachable to each other.
Use the command...
system-view
ipv6
interface tunnel number
ip address ip-address { mask |
mask-length } [ sub ]
tunnel-protocol ipv4-ipv6
source { ipv6-address |
interface-type interface-number }
destination ipv6-address
Figure 74, the two subnets Group 1 and Group 2 are connected over an IPv6 network.
Remarks
—
Required
By default, the IPv6 packet forwarding
function is disabled.
—
Required
By default, no IPv4 address is configured
for the tunnel interface.
Optional
GRE over IPv4 tunnel by default.
The same tunnel mode should be
configured at both ends of the tunnel.
Otherwise, packet delivery will fail.
Required
By default, no source address or interface
is configured for the tunnel.
Required
By default, no destination address is
configured for the tunnel.
