VPP IPIP Configuration
######################
VPP IPIP interfaces provide IP-in-IP tunneling with high-performance packet processing. IPIP tunnels encapsulate IP packets within IP packets, creating point-to-point connections across Layer 3 networks.
Basic Configuration
-------------------
Creating an IPIP Interface
^^^^^^^^^^^^^^^^^^^^^^^^^^
.. cfgcmd:: set vpp interfaces ipip <ipipN>
Create an IPIP interface where ``<ipipN>`` follows the naming convention ipip1, ipip2, etc.
.. cfgcmd:: set vpp interfaces ipip <ipipN> remote <address>
Set the tunnel remote endpoint address. Supports both IPv4 and IPv6 addresses.
.. cfgcmd:: set vpp interfaces ipip <ipipN> source-address <address>
Set the tunnel source address. Must match an address configured on the local system.
**Basic Example:**
.. code-block:: none
set vpp interfaces ipip ipip1
set vpp interfaces ipip ipip1 remote 203.0.113.2
set vpp interfaces ipip ipip1 source-address 192.168.1.1
Interface Configuration
-----------------------
Description and Administrative Control
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. cfgcmd:: set vpp interfaces ipip <ipipN> description <description>
Set a descriptive name for the IPIP interface.
.. cfgcmd:: set vpp interfaces ipip <ipipN> disable
Administratively disable the IPIP interface.
Kernel Interface Integration
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. cfgcmd:: set vpp interfaces ipip <ipipN> kernel-interface <interface-name>
Bind a kernel interface to the IPIP tunnel for management and application compatibility.
For detailed information about kernel interface integration, see :doc:`kernel`.
Configuration Examples
----------------------
IPv4 IPIP Tunnel
^^^^^^^^^^^^^^^^
.. code-block:: none
# Basic IPv4 IPIP tunnel
set vpp interfaces ipip ipip1
set vpp interfaces ipip ipip1 description "Site-to-site IPIP tunnel"
set vpp interfaces ipip ipip1 remote 203.0.113.10
set vpp interfaces ipip ipip1 source-address 192.168.1.1
IPv6 IPIP Tunnel
^^^^^^^^^^^^^^^^
.. code-block:: none
# IPv6 endpoints
set vpp interfaces ipip ipip2
set vpp interfaces ipip ipip2 remote 2001:db8::2
set vpp interfaces ipip ipip2 source-address 2001:db8::1
IPIP with Kernel Interface
^^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: none
# IPIP tunnel with management interface
set vpp interfaces ipip ipip3
set vpp interfaces ipip ipip3 remote 203.0.113.30
set vpp interfaces ipip ipip3 source-address 192.168.1.1
set vpp interfaces ipip ipip3 kernel-interface vpptun3
set vpp kernel-interfaces vpptun3 address 10.0.2.1/30
