Layer 2 VPN

  • Support for Redundant Pseudowires for Virtual Private LAN Service (VPLS) (ACX7024)—Starting in Junos OS Evolved 22.3R1, VPLS with LDP hot-standby, cold-standby model, and without BFD or CFM trigger is supported.

    [See Redundant Pseudowires for Layer 2 Circuits and VPLS.]

  • Support for Redundant Pseudowire Layer 2 Circuits (ACX7024)—Starting in Junos OS Evolved 22.3R1, ACX7024 supports redundant pseudowire Layer 2 Circuits. Multichassis Link Aggregation Group (MC-LAG) is not supported with redundant pseudowire Layer 2 circuits.

    [See Redundant Pseudowires for Layer 2 Circuits and VPLS.]

  • Flow-Aware Transport for Pseudowires (FAT) label and Entropy label support for Layer 2 circuit and Layer 2 VPN (ACX7024)—Starting in Junos OS Evolved 22.3R1, VPLS with LDP hot-standby, cold-standby model, and without BFD or CFM trigger is supported.

    FAT Label support includes these features:

    • Transmit and receive direction on Layer 2 circuits and Layer 2 VPNs

    • Transmit and receive direction on Layer 2 VPN

    • Layer 2 VPN with multihoming

    • Layer 2 circuits with redundant pseudowire

    • Load balancing over LAG

    • Static flow label for Layer 2 circuits

    Entropy Label support includes these features:

    • Entropy label indication for LDP and RSVP transport

    • Load balancing over LAG
