Configuring 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.

For information on the configuration procedures specific to Layer 2 VPNs, Layer 3 VPNs, and VPLS, see the following configuration chapters:

This chapter describes the general procedures required to configure Layer 2 VPNs, Layer 3 VPNs, virtual-router routing instances, and VPLS, discussing the following topics:

• Enabling a Signaling Protocol on the PE Routers
• Configuring an IGP on the PE and P Routers
• Configuring an IBGP Session Between PE Routers
• Configuring a VPN Routing Instance on the PE Routers
• Configuring a Virtual-Router Routing Instance
• Configuring Graceful Restart
• Configuring Redundant Pseudowires for Layer 2 Circuits and VPLS
• Configuring Aggregate Labels for VPNs
• Rewriting Markers and VPNs
• Transmitting Nonstandard BPDUs
• Pinging VPNs and Layer 2 Circuits
• Configuring a Path MTU Check for VPNs
• Enabling Unicast Reverse-Path Forwarding Check for VPNs
