MPIP(4) FreeBSD Kernel Interfaces Manual MPIP(4)
NAME
mpip - MPLS IP layer 2 pseudowire
SYNOPSIS
pseudo-device mpip
DESCRIPTION
The mpip interface is used to create an MPLS IP layer 2 tunnel between
two points.
An mpip interface can be created at runtime using the ifconfig mpipN
create command, or by setting up a hostname.if(5) configuration file for
netstart(8). The interface itself can be configured with ifconfig(8).
The local MPLS label, the remote MPLS label and neighbor, use of
pseudowire control words, or flow-aware transport are normally configured
after negotiation with a remote system using ldpd(8), but it is also
possible to configure them manually using ifconfig(8).
EXAMPLES
Create a pseudowire with local label 20 and remote label 21 on neighbor
10.254.0.1:
# ifconfig mpip5 create
# ifconfig mpip5 mplslabel 20 pweneighbor 21 10.254.0.1
# ifconfig mpip5 up
Disable the use of the Pseudowire Emulation Edge-to-Edge (PWE3) Control
Word, and enable the use of a Flow label for Flow-Aware Transport of
Pseudowires:
# ifconfig mpip5 -pwecw pwefat
