Configuration Procedure - HP 3600 v2 Series Configuration Manual

The source address and destination address of a tunnel uniquely identify a path. They must be
•
configured at both ends of the tunnel and the source address at one end must be the destination
address at the other end and vice versa.
The source address or interface and the destination address that are specified for the tunnel
•
interface must be a public address or interface.
• Tunnel interfaces using the same encapsulation protocol must have different source addresses and
destination addresses.
If you configure a source interface for a tunnel interface, the tunnel interface takes the primary IP
•
address of the source interface as its source address.
When configuring a route through the tunnel, you are not allowed to set up a static route whose
•
destination address is in the subnet of the tunnel interface. Instead, you can do one of the following:
Configure a static route, using the address of the network segment the original packet is
destined for as its destination address and the address of the peer tunnel interface as its next
hop.
Enable a dynamic routing protocol on both the tunnel interface and the router interface
connecting the private network, so that the dynamic routing protocol can establish a routing
entry that allows the tunnel to forward packets through the tunnel.

Configuration procedure

To configure a GRE over IPv6 tunnel:
Step
1. Enter system view.
2. Enable the IPv6 packet
forwarding function.
3. Create a tunnel interface and
enter tunnel interface view.
4. Configure an IPv4 address for
the tunnel interface.
5. Set the tunnel mode to GRE
over IPv6.
6. Configure the source address
or interface for the tunnel
interface.
7. Configure the destination
address for the tunnel
interface.
8. Return to system view.
9. Configure the device to
discard the IPv4-compatible
IPv6 packets.

Remarks
N/A
Disabled by default.
By default, there is no tunnel
interface on a device.
By default, no IPv4 address is
configured for a tunnel interface.
By default, the tunnel is a GRE over
IPv4 tunnel.
You must configure the same tunnel
mode on both ends of a tunnel.
Otherwise, packet delivery will
fail.
By default, no source address or
interface is configured for a tunnel
interface.
By default, no destination address
is configured for a tunnel interface.
N/A
Optional.
By default, the device does not
discard the IPv4-compatible IPv6
packets.
