NAME
rport —
rdomain port interface
pseudo-device
SYNOPSIS
pseudo-device rport
DESCRIPTION
The rport driver provides point-to-point
interfaces for layer 3 connectivity between
rdomain(4) instances.
Layer 3 connectivity between a pair of rdomains can be established
by creating an rport interface in each rdomain, and
connecting them together by configuring one of these interfaces as the
parent of the other.
rport interfaces can be created at runtime
using the ifconfig rportN
create command or by setting up a
hostname.if(5) configuration file for
netstart(8). The interface itself can be configured with
ifconfig(8); see its manual page for more information.
EXAMPLES
Create two rport interfaces in separate
rdomain(4) instances and connect them together:
# ifconfig rport0 create rdomain 0 up # ifconfig rport1 create rdomain 1 parent rport0 up # ifconfig rport0 inet 192.168.0.0/32 192.168.0.1 # ifconfig rport1 inet 192.168.0.1/32 192.168.0.0

HISTORY
The rport driver first appeared in
OpenBSD 7.6.

CAVEATS
A pair of rport interfaces must be created
for each connection between a pair of rdomains. Alternatively, if peering
between multiple rdomain(4) instances is required, a single
veb(4) interface
with a vport(4) interface for each rdomain can be used instead.
