  • Support for hierarchical VPLS mesh groups and hot-standby convergence (ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7332, ACX7348, and ACX7509)—Starting in Junos OS Evolved Release 24.2R1, you can configure mesh groups in an hierarchical VPLS (H-VPLS) network. The router supports:

    • Up to 3 mesh-groups with no-local switching in a single VPLS routing instance.

    • A total maximum of 14 mesh-groups with either local switching or no-local switching per routing instance.

    To configure mesh groups on ACX Series routers:

    • Configure the routing-instances routing-instance-name protocols vpls statement on the routers in the mesh group in the routing instance.

    • Include the system packet-forwarding-options system-profile vpls-meshgroups statement on the routers in the H-VPLS network. The packet forwarding engine (PFE) restarts upon the issue of this command.

    When you enable vpls-hot-standby-convergence, the Junos device sends advertising messages with different labels on the active and standby pseudowire. The spoke device can then differentiate the return messages coming back from the active and standby pseudowire. To enable hot-standby convergence improvement, include the set routing-options forwarding-table vpls-hotstandby-convergence statement at the spoke devices.
