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 interfaces vpp ipip <vppipipN>
Create an IPIP interface where ``<vppipipN>`` follows the naming
convention ``vppipip1``, ``vppipip2``, etc.
.. cfgcmd:: set interfaces vpp ipip <vppipipN> remote <address>
Set the tunnel remote endpoint address. Supports both IPv4 and IPv6
addresses.
.. cfgcmd:: set interfaces vpp ipip <vppipipN> source-address <address>
Set the tunnel source address. The source address must match an address
configured on the local system.
**Basic Example:**
.. code-block:: none
set interfaces vpp ipip vppipip1
set interfaces vpp ipip vppipip1 remote 203.0.113.2
set interfaces vpp ipip vppipip1 source-address 192.168.1.1
Interface Configuration
-----------------------
Description and Administrative Control
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. cfgcmd:: set interfaces vpp ipip <vppipipN> description <description>
Set a descriptive name for the IPIP interface.
.. cfgcmd:: set interfaces vpp ipip <vppipipN> disable
Administratively disable the IPIP interface.
Kernel Interface Integration
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Kernel interface is bound to the VPP IPIP interface for management and
application compatibility.
IP Address Configuration
------------------------
.. cfgcmd:: set interfaces vpp ipip <vppipipN> address <ip-address/prefix>
Configure IPv4 or IPv6 addresses on the kernel interface. Multiple
addresses can be assigned.
**Examples:**
.. code-block:: none
# IPv4 address
set interfaces vpp ipip vppipip0 address 192.168.1.10/24
# IPv6 address
set interfaces vpp ipip vppipip0 address 2001:db8::10/64
MTU Configuration
-----------------
.. cfgcmd:: set interfaces vpp ipip <vppipipN> mtu <size>
Set the Maximum Transmission Unit (MTU) for the kernel interface.
The MTU must be compatible with the connected VPP interface.
Configuration Examples
----------------------
IPv4 IPIP Tunnel
^^^^^^^^^^^^^^^^
.. code-block:: none
# Basic IPv4 IPIP tunnel
set interfaces vpp ipip vppipip1
set interfaces vpp ipip vppipip1 description "Site-to-site IPIP tunnel"
set interfaces vpp ipip vppipip1 remote 203.0.113.10
set interfaces vpp ipip vppipip1 source-address 192.168.1.1
IPv6 IPIP Tunnel
^^^^^^^^^^^^^^^^
.. code-block:: none
# IPv6 endpoints
set interfaces vpp ipip vppipip2
set interfaces vpp ipip vppipip2 remote 2001:db8::2
set interfaces vpp ipip vppipip2 source-address 2001:db8::1
IPIP with Kernel Interface
^^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: none
# IPIP tunnel with management interface
set interfaces vpp ipip vppipip3
set interfaces vpp ipip vppipip3 remote 203.0.113.30
set interfaces vpp ipip vppipip3 source-address 192.168.1.1
set interfaces vpp ipip vppipip3 address 10.0.2.1/30
