Supported VPN, VPLS, and Layer 2 Circuit Standards

The JUNOS software substantially supports the following Internet draft for Layer 2 VPNs: draft-kompella-ppvpn-l2vpn-03.txt, Layer 2 VPNs Over Tunnels.

The JUNOS software substantially supports the following Layer 3 VPN standards:

• RFC 1918, Address Allocation for Private Internets
• 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 JUNOS software supports the traceroute functionality, but 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 JUNOS software supports the following interprovider and carrier-of-carriers VPN standards:

• RFC 3107, Carrying Label Information in BGP-4
• RFC 4364, BGP/MPLS IP Virtual Private Networks (VPNs)
• Internet draft draft-marques-ppvpn-ibgp-00.txt, RFC2547bis networks using internal BGP as PE-CE protocol

The JUNOS software substantially supports the following multicast VPN standards:

• Internet draft draft-ietf-l3vpn-2547bis-mcast-bgp-03.txt, BGP Encodings and Procedures for Multicast in MPLS/BGP IP VPNs
• Internet draft draft-ietf-l3vpn-2547bis-mcast-02.txt, Multicast in MPLS/BGP IP VPNs

The JUNOS software substantially supports the following virtual private LAN service (VPLS) standards:

• RFC 4761, Virtual Private LAN Service (VPLS) Using BGP for Auto-Discovery and Signaling
• RFC 4762, Virtual Private LAN Service (VPLS) Using Label Distribution Protocol (LDP) Signaling (FEC 128, control bit 0, and Ethernet pseudowire type hexadecimal 0x0005)

The JUNOS software substantially supports the following Layer 2 circuit standards:

• Internet draft draft-martini-l2circuit-encap-mpls-07.txt, Encapsulation Methods for Transport of Layer 2 Frames Over IP and MPLS Networks

  The JUNOS software differs from the Internet draft in the following ways:

  • A packet with a sequence number of 0 is treated as out of sequence.
  • Any packet that does not have the next incremental sequence number is considered out of sequence.
  • When out-of-sequence packets arrive, the expected sequence number for the neighbor is set to the sequence number in the Layer 2 circuit control word.
• Internet draft draft-martini-l2circuit-trans-mpls-14.txt, Transport of Layer 2 Frames Over MPLS
