NAME
mpe —
MPLS Provider Edge
SYNOPSIS
pseudo-device mpe
DESCRIPTION
The mpe interface is a Multiprotocol Label

An mpe interface can be created at runtime

hostname.if(5) configuration file for
netstart(8). The interface itself can be configured with
ifconfig(8); see its manual page for more information.
