NAME
ifcfg-vxlan - Virtual eXtended LAN interface configuration
SYNOPSIS
/etc/sysconfig/network/ifcfg-*
VXLANs
To setup a vxlan interface, you need a configuration file that containsthe following variable set to
yes:
- VXLAN { yes | no }
It may contain also the following options:
- VXLAN_ID { 0..16777215 }
- Specifies the VXLAN Network Identifier (Segment Identifier).
- VXLAN_DEVICE { <name> }
- Specifies the link device name to use for tunnel endpoint communication.
- VXLAN_REMOTE_IP { <IPv4> | <IPv6> }
- Specifies the unicast or multicast destination IP address. A multicastaddress requires a link device in via VXLAN_DEVICE.
- VXLAN_LOCAL_IP { <IPv4> | <IPv6> }
- Specifies source IP address to use in outgoing packets.
- VXLAN_DST_PORT { 0..65535 }
- The UDP destination port of the remote tunnel endpoint. IANA assignedport is 4789 while the linux kernel is using port 8472.
- VXLAN_SRC_PORT_LOW { 0..65535 }
- VXLAN_SRC_PORT_HIGH { 0..65535 }
- The UDP source port range to use in communication with tunnel endpoint.
- VXLAN_TTL { 0..255 }
- The TTL aka hop-limit for to use in outgoing packets.
- VXLAN_TOS { 0..255 }
- The TOS to set in outgoing packets.
- VXLAN_AGEING { 0 | <secs> }
- Lifetime in seconds of the FDB entries in the kernel.
- VXLAN_MAX_ADDRS { 0 | <max> }
- Maximal number of addresses/entries in the FDB.
- VXLAN_LEARNING { yes | no }
- Disables to not learn unknown source link layer address.
- VXLAN_PROXY { yes | no }
- Enables ARP/NDP proxy.
- VXLAN_RSC { yes | no }
- Enables route short circuit.
- VXLAN_L2MISS { yes | no }
- Enables netlink link-layer address miss notification generation.
- VXLAN_L3MISS { yes | no }
- Enables netlink ip address miss notification generation.
- VXLAN_UDP_CSUM { yes | no }
- Enables to calculate UDP checksums.
- VXLAN_UDP6_ZERO_CSUM_TX { yes | no }
- Enables to calculate UDP checksums.
- VXLAN_UDP6_ZERO_CSUM_RX { yes | no }
- Specified if UDP checksums are received.
- VXLAN_REM_CSUM_TX { yes | no }
- Enables/disables transmit checksum offloading.
- VXLAN_REM_CSUM_RX { yes | no }
- Enables/disables receive checksum offloading.
- VXLAN_REM_CSUM_PARTIAL { yes | no }
- Disables partial gro checksum handling.
- VXLAN_COLLECT_METADATA { yes | no }
- Whether to collect metadata on external control plane of interal FDB.
- VXLAN_GBP { yes | no }
- Enables Group Policy extension.
An ifcfg- file for the interface specified by VXLAN_DEVICE mustalso be provided. In the most basic case, it should at least containSTARTMODE='auto'.
The rest of the VXLAN interface IP and routes configuration do not differfrom ordinary interfaces. See also man ifcfg and man routesfor details.
EXAMPLES
- Sets up vxlan0 vxlan interface on top of eth0:
ifcfg-vxlan0
STARTMODE='auto' VXLAN='yes' IPADDR='192.168.3.27/24'
- Sets up vxlan0 vxlan interface with an ID/VNI 1 and linked to the eth0 device:
ifcfg-vxlan0
STARTMODE='auto' VXLAN='yes' VXLAN_DEVICE='eth0'
