Bridge BRIDGE(4) - Device Drivers Manual # BRIDGE(4) - Device Drivers Manual
NAME # bridge - Ethernet bridge interface
SYNOPSIS # pseudo-device bridge
#include <sys/types.h>
#include <net/if.h>
#include <netinet/in.h>
#include <netinet/if_ether.h>
#include <net/if_bridge.h>
DESCRIPTION # The bridge device creates a logical link between two or more Ethernet interfaces or encapsulation interfaces (see [etherip(4)](/man/man4/etherip.4)). This link between the interfaces selectively forwards frames from each interface on the bridge to every other interface on the bridge.

PAIR(4) - Device Drivers Manual # PAIR(4) - Device Drivers Manual
NAME # pair - virtual Ethernet interface pair
SYNOPSIS # pseudo-device pair
DESCRIPTION # The pair interface simulates a normal Ethernet interface by encapsulating standard network frames with an Ethernet header, specifically for use in a pair of interfaces that are interconnected with each other.
To use it, the administrator needs to create two pair interfaces and connect them; the interfaces are ‘patched’, as would be done with physical network 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.
