Supported Layer 3 VPN Standards

Junos OS substantially supports the following RFCs, which define standards for Layer 3 virtual private networks (VPNs).

  • RFC 2283, Multiprotocol Extensions for BGP-4

  • RFC 2685, Virtual Private Networks Identifier

  • RFC 2858, Multiprotocol Extensions for BGP-4

  • RFC 4364, BGP/MPLS IP Virtual Private Networks (VPNs)

  • RFC 4379, Detecting Multi-Protocol Label Switched (MPLS) Data Plane Failures

    The traceroute functionality is supported only on transit routers.

  • RFC 4576, Using a Link State Advertisement (LSA) Options Bit to Prevent Looping in BGP/MPLS IP Virtual Private Networks (VPNs)

  • RFC 4577, OSPF as the Provider/Customer Edge Protocol for BGP/MPLS IP Virtual Private Networks (VPNs)

  • RFC 4659, BGP-MPLS IP Virtual Private Network (VPN) Extension for IPv6 VPN

  • RFC 4684, Constrained Route Distribution for Border Gateway Protocol/MultiProtocol Label Switching (BGP/MPLS) Internet Protocol (IP) Virtual Private Networks (VPNs)

The following RFCs do not define a standard, but provide information about technology related to Layer 3 VPNs. The IETF classifies them as a “Best Current Practice” or “Informational.”

  • RFC 1918, Address Allocation for Private Internets

  • RFC 2917, A Core MPLS IP VPN Architecture
