mpeMPLS Provider Edge

pseudo-device mpe

The mpe interface is a Multiprotocol Label Switching (MPLS) Provider Edge pseudo-device used to enter and leave an MPLS domain.

An mpe interface can be created at runtime using the ifconfig mpeN 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.

mpe interfaces support the following unique ioctls:

Encapsulate packets entering this interface in MPLS using the specified label.
Report the label that packets entering this interface will be tagged with.

sysctl(3), hostname.if(5), ifconfig(8), ldpd(8), netstart(8)

The mpe device first appeared in OpenBSD 4.4.

The mpe driver was written by Pierre-Yves Ritschard <>.
