Manual:Interface/Virtual-ethernet
(Redirected from Virtual-ethernet)
Applies to RouterOS: v4.x
Summary
To connect your virtual routers to RouterOS host system you either have to assign interface for your guest (possible only on MetaROUTER) or you can add virtual Ethernet interface that is described in this document.
May contain either static or dynamic interface. Static interfaces should be configured in virtual-ethernet menu and then assigned to virtual machine in /kvm interface (for KVM) or /metarouter interface (for MetaROUTER). Dynamic interfaces will be recreated automatically on each reboot and will contain new MAC address.
Note: Virtual-ethernets will be automatically removed even if configured as static in /kvm interface menu
Requirements
This menu becomes available:
- on x86 architeecture you have to have kvm packge installed
- on mipsbe architecture RouterBOARDS
- on ppc architecture RouterBOARDS, except RB333, RB600 and variants.
Virtual Ethernet creation
Menu: /interface virtual-ethernet add
| Property | Desciption |
|---|---|
| arp (disabled | enabled | proxy-arp | reply-only, default: enabled) | ARP protocol resolution mode:
|
| comment (text) | Short description of the item |
| copy-from (number) | Item number to copy settings from to create new item |
| disabled (yes | no default: yes) | identifies if entry is part of active coniguration |
| mac-address (MAC address default: automatically generated) | MAC address of interface. If automatically generated, then this pattern will be used 02:XX:XX:XX:XX:XX |
| mtu (0 65536 default: 1500) | maximal transmission unit of the interface |
| name (text default: tapX or vifX) | Interface name where, if auto-generated, X is inreased if previous valid number already exists, starts with 1. tap is on x86 vif is on RouterBOARD platform. |
