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
Create an IPIP interface where <ipipN> follows the naming convention ipip1, ipip2, etc.
Set the tunnel remote endpoint address. Supports both IPv4 and IPv6 addresses.
Set the tunnel source address. Must match an address configured on the local system.
Basic Example:
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
Set a descriptive name for the IPIP interface.
Kernel Interface Integration
Bind a kernel interface to the IPIP tunnel for management and application compatibility.
For detailed information about kernel interface integration, see VPP Kernel Interfaces Configuration.
Configuration Examples
IPv4 IPIP Tunnel
# 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
# 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
# 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
