Configure VPNs
Layer 2 virtual private networks (VPNs), Layer 3 VPNs, virtual-router routing instances, and virtual private LAN service (VPLS) use a common infrastructure within JUNOS and common configuration procedures. This chapter describes the common configuration steps. Complete these configuration steps, regardless of which type of VPN you are configuring, before proceeding to the more specific configuration steps described in other chapters.
This chapter describes how to configure Layer 2 VPNs, Layer 3 VPNs, virtual-router routing instances, and VPLS, discussing the following topics:
- Enable a Signaling Protocol on the PE Routers
- Configure an IGP on the PE and P Routers
- Configure an IBGP Session between PE Routers
- Configure a VPN Routing Instance on the PE Routers
- Configure a Virtual-Router Routing Instance
- Configure Graceful Restart
- Configure Aggregate Labels for VPNs
- Rewrite Markers and VPNs
- Transmit Nonstandard BPDUs
- Ping VPNs and Layer 2 Circuits
- Configure a Path MTU Check for VPNs
