Example: Configuring MPLS on the VPLS PE Router

This example shows how to configure MPLS on the VPLS PE router.

Requirements

Before you begin:

Before you begin, see Understanding Selective Stateless Packet-Based Services in the Junos OS Security Configuration Guide .
Configure the interfaces that will carry the VPLS traffic between the PE router and the CE devices. SeeExample: Configuring Routing Interfaces on the VPLS PE Router and Example: Configuring the Interface to the VPLS CE Device.
Create a VPLS routing instance on each PE router that is participating in the VPLS. See Example: Configuring the VPLS Routing Instance.
Configure an IGP on the PE routers to exchange routing information. See Example: Configuring OSPF on the VPLS PE Router.
Configure RSVP-TE on the PE routers. See Example: Configuring RSVP on the VPLS PE Router.

Overview

This example shows you how to configure MPLS on the PE1 router to advertise the Layer 2 VPN interface that communicates with the PE2 router.

Caution: MPLS is disabled by default on J Series and SRX Series devices. You must explicitly configure your router to allow MPLS traffic. However, when MPLS is enabled, all flow-based security features are deactivated and the router performs packet-based processing. Flow-based services such as security policies, zones, NAT, ALGs, chassis clustering, screens, firewall authentication, and IPsec VPNs are unavailable on the router.

Configuration

Step-by-Step Procedure

To configure MPLS on the VPLS PE router:

Configure the interface to the PE2 router for MPLS.
[edit ]user@host# set protocols mpls interface t1-1/0/1.0
Configure the loopback for MPLS.
[edit ]user@host# set protocols mpls interface lo0.0
Configure the path to destination 10.255.7.164.
[edit ]user@host# set protocols mpls label-switched-path chelsea-sagar to 10.255.7.164
If you are done configuring the device, commit the configuration.
[edit ]user@host# commit

Verification

To verify the configuration is working properly, enter the show mpls command.
