MPE(4)                   BSD Kernel Interfaces Manual                   MPE(4)

NAME
     mpe -- MPLS Provider Edge

SYNOPSIS
     pseudo-device mpe

DESCRIPTION
     The mpe interface is an 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:

        SIOCSETLABEL  Encapsulate packets entering this interface in MPLS
                      using the specified label.

        SIOCGETLABEL  Report the label that packets entering this interface
                      will be tagged with.

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

HISTORY
     The mpe device first appeared in OpenBSD 4.4.
