RC(8) - System Manager’s Manual # RC(8) - System Manager’s Manual
NAME # rc, rc.firsttime, rc.local, rc.securelevel - command scripts for system startup
DESCRIPTION # rc is the command script that is invoked by init(8) when the system starts up. It performs system housekeeping chores and starts up system daemons. Additionally, rc is intricately tied to the netstart(8) script, which runs commands and daemons pertaining to the network. rc is also used to execute any rc.

ROUTE(8) - System Manager’s Manual # ROUTE(8) - System Manager’s Manual
NAME # route - manually manipulate the routing tables
SYNOPSIS # route [-dnqtv] [-T rtable] command [[modifier …] arg …]
DESCRIPTION # At system start, routing tables are initialised and configured by netstart(8). The route utility can be used to view or manually manipulate the network routing tables. Only the superuser may modify the routing tables.
The options are as follows:

SEC(4) - Device Drivers Manual # SEC(4) - Device Drivers Manual
NAME # sec - route based IPsec VPN tunnel interface pseudo-device
SYNOPSIS # pseudo-device sec
DESCRIPTION # The sec driver provides point-to-point tunnel interfaces for IPv4 and IPv6 protected by the ipsec(4) Encapsulating Security Payload (ESP) protocol.
Traffic is encapsulated in the ESP protocol and forwarded to the remote endpoint by routing over a sec interface rather than matching policy in the IPsec Security Policy Database (SPD).

TAP(4) - Device Drivers Manual # TAP(4) - Device Drivers Manual
NAME # tap - Ethernet tunnel pseudo-device
SYNOPSIS # pseudo-device tun
#include <sys/types.h>
#include <net/if_tun.h>
DESCRIPTION # The tap driver provides an Ethernet interface pseudo-device. Packets sent to this interface can be read by a userland process and processed as desired. Packets written by the userland process are injected back into the kernel networking subsystem.
A tap interface can be created at runtime using the ifconfig tap‌N create command or by opening the character special device /dev/tapN.

TPMR(4) - Device Drivers Manual # TPMR(4) - Device Drivers Manual
NAME # tpmr - IEEE 802.1Q Two-Port MAC Relay interface
SYNOPSIS # pseudo-device tpmr
DESCRIPTION # The tpmr driver implements an 802.1Q (originally 802.1aj) Two-Port MAC Relay (TPMR). A TPMR is a simplified Ethernet bridge with exactly two member ports, and it unconditionally relays Ethernet packets between those ports.
tpmr interfaces can be created at runtime using the ifconfig tpmr‌N create command or by setting up a hostname.
...
TRUNK(4) - Device Drivers Manual # TRUNK(4) - Device Drivers Manual
NAME # trunk - link aggregation and link failover interface
SYNOPSIS # pseudo-device trunk
DESCRIPTION # The trunk interface allows aggregation of multiple network interfaces as one virtual trunk interface.
A trunk interface can be created using the ifconfig trunk‌N create command.
The driver currently supports the trunk protocols broadcast, failover, lacp, loadbalance, none, and roundrobin (the default). The protocols determine which ports are used for outgoing traffic and whether a specific port accepts incoming traffic.

TUN(4) - Device Drivers Manual # TUN(4) - Device Drivers Manual
NAME # tun - network tunnel pseudo-device
SYNOPSIS # pseudo-device tun
#include <sys/types.h>
#include <net/if_tun.h>
DESCRIPTION # The tun driver provides a network interface pseudo-device. Packets sent to this interface can be read by a userland process and processed as desired. Packets written by the userland process are injected back into the kernel networking subsystem.
A tun interface can be created at runtime using the ifconfig tun‌N create command or by opening the character special device /dev/tunN.

VEB(4) - Device Drivers Manual # VEB(4) - Device Drivers Manual
NAME # veb, vport - Virtual Ethernet Bridge network device
SYNOPSIS # pseudo-device veb
DESCRIPTION # The veb pseudo-device supports the creation of a single layer 2 Ethernet network between multiple ports. Ethernet interfaces are added to the veb bridge to be used as ports. Unlike bridge(4), veb takes over the operation of the interfaces that are added as ports.
...
VETHER(4) - Device Drivers Manual # VETHER(4) - Device Drivers Manual
NAME # vether - virtual Ethernet interface
SYNOPSIS # pseudo-device vether
DESCRIPTION # 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.
...
VLAN(4) - Device Drivers Manual # VLAN(4) - Device Drivers Manual
NAME # vlan, svlan - IEEE 802.1Q and 802.1ad pseudo-device
SYNOPSIS # pseudo-device vlan
DESCRIPTION # The vlan driver provides network interfaces supporting Virtual Local Area Networks (VLANs) on Ethernet networks. vlan interfaces implement virtual networks using the IEEE 802.1Q protocol. svlan interfaces implement virtual networks using the IEEE 802.1ad protocol.
svlan interfaces allow construction of IEEE 802.1ad-compliant provider bridges.
