Manual:Interface/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 here if under /kvm interface (for KVM or /metarouter interface for MetaROUTER. Dynamic interfaces will be recreated automatically each reboot and will contain new MAC address.

Requirements

Menu is only available if KVM package is installed on x86 architecture, or on RouterOS running on selected RouterBOARDS.

Virtual Ethernet creation

Menu: /interface virtual-ethernet add

Property	Desciption
arp (disabled | enabled | proxy-arp | reply-only, default: enabled)	ARP protocol resolution mode: disabled - interface is not replying to ARP requests enabled - interface is replaying to all ARP requests on its MAC address proxy-arp - interface is replying to all ARP requests reply-only - interface replies only to known (static entries in ARP table) sources
