The information in this page is updated in accordance with firmware version RUTM_R_00.07.10.

VXLAN

Virtual Extensible LAN is a tunneling interface protocol (VXLAN), which allows VXLAN layer 2 virtualization over layer 3 network. VXLAN establishes a logical tunnel between the source and destination network devices, through which it uses MAC-in-UDP encapsulation for packets. In addition, it helps customer sites to configure layer2 VPN.

Note: VXLAN is additional software that can be installed from the System → Package Manager page.

VNI	integer [1..16777215]; default: 1	VXLAN network identifier.
PORT	integer [1..65535]; default: 4789	VXLAN network identifier.
Local address	ip; default: none	Sets the local source IP address for VXLAN tunneling.
Remote address	ip; default: none	Specifies the multicast group or remote IP address used for VXLAN tunneling.
Ageing	integer [1..4294967295]; default: empty	Specifies the lifetime in seconds of FDB entries learnt by the kernel.
Max FDB entries	integer [1..4294967295]; default: empty	Specifies the maximum number of FDB entries.
IPv4 checksum	off | on; default: off	Specifies if UDP checksum is calculated for transmitted packets over IPv4.
Learning	off | on; default: off	Enables or disables MAC learning for VXLAN.
Proxy	off | on; default: off	Enables or disables ARP proxy for VXLAN.
RSC	off | on; default: off	Specifies if route short circuit is turned on.
L2miss	off | on; default: off	Specifies if netlink LLADDR miss notifications are generated.
L3miss	off | on; default: off	Specifies if netlink IP ADDR miss notifications are generated.
IPv6 TX checksum	off | on; default: off	Enables or disables UDP checksum calculation for transmitted packets over IPv6.
IPv6 RX checksum	off | on; default: off	Allow incoming UDP packets over IPv6 with zero checksum field.
