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.
