Configuration Procedure; Configuration Example - HP 3600 v2 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.
The IPv4 address of the local tunnel interface cannot be on the same subnet as the destination
•
address of the tunnel.
• The destination address of a route with a 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

To configure an IPv4 over IPv4 tunnel:
Step
1. Enter system view.
2. Enter tunnel interface view.
3. Configure an IPv4 address
for the tunnel interface.
4. Specify the IPv4 over IPv4
tunnel mode.
5. Configure a source
address or interface for the
tunnel interface.
6. Configure a destination
address for the tunnel
interface.

By default, no IPv4 address is
configured for the tunnel interface.

The same tunnel mode should be
configured at both ends of the tunnel.
Otherwise, packet delivery will fail.
By default, no source address or
interface is configured for the tunnel.
By default, no destination address is
configured for the tunnel.
