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 Ethernet, DS1, DS3, and Serial 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.
