vether
—
virtual Ethernet interface
pseudo-device vether
The
vether
interface simulates a normal Ethernet
interface by encapsulating standard network frames with an Ethernet header,
specifically for use as a member in a
bridge(4).
To use vether
the administrator needs to
configure an address onto the interface so that packets can be routed to it.
An Ethernet header will be prepended and, if the
vether
interface is a member of a
bridge(4), the frame will show up
there.
bridge(4),
inet(4),
inet6(4),
hostname.if(5),
ifconfig(8),
netstart(8)
The
vether
interface first appeared in
OpenBSD 4.7.

Like
tun(4), the Ethernet address chosen will be
partially random, and may occasionally collide with another address.
