Supported Layer 3 VPN Standards

The 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 [sic] 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 [sic] Label Switching (BGP/MPLS) Internet Protocol (IP) Virtual Private Networks (VPNs)

The following RFC does not define a standard, but provides information about technology related to Layer 3 VPNs. The IETF classifies it as a “Best Current Practice.”

• RFC 1918, Address Allocation for Private Internets
