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.
