Before You Begin

Before you begin configuring VPNs, perform the following tasks:

• Determine which Services Routers are participating in the VPN configuration. This chapter describes configuring an interface for basic VPN connectivity. To configure an interface, see Configuring Network Interfaces.

• Determine the protocols to use in the VPN configuration. These protocols include
  • MPLS—See Multiprotocol Label Switching Overview and the JUNOS Routing Protocols Configuration Guide.
  • BGP, EBGP, and internal BGP (IBGP)—See Configuring BGP Sessions and the JUNOS Routing Protocols Configuration Guide.
  • LDP and Resource Reservation Protocol (RSVP)—See Configuring Signaling Protocols for Traffic Engineering and the JUNOS MPLS Applications Configuration Guide.
  • OSPF—See Configuring an OSPF Network and the JUNOS Routing Protocols Configuration Guide.
