MPE(4)

NAME
mpe - MPLS Provider Edge

SYNOPSIS
pseudo-device mpe

DESCRIPTION
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.
