mpip4

Usage

Overview

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
