Services Applications

  • FTIs with support for UDP encapsulation (ACX7024, ACX7024X, ACX7100-48L, ACX7100-32C, ACX7332, ACX7348, and ACX7509)—Starting in Junos OS Evolved Release 24.2R1, you can configure flexible tunnel interfaces (FTIs) that provide support for static UDP tunnels only.

    With the UDP tunnels-over-FTI feature, you can benefit from better traffic distribution over ECMP, which is achieved by the UDP source port derived from the hash value of the inner payload. The other benefits of this feature include shortened interface hop counts, smooth IGP domain separation, and reduced operational complexity.

  • MPLS support for FTI tunnels ( ACX7024X, ACX7100-48L, ACX71000-32C, ACX7024, ACX7509, ACX7348 and ACX7332)—Starting In Junos OS Evolved Release 24.2R1, you can configure MPLS protocols over flexible tunnel interfaces (FTIs), thereby transporting MPLS packets over IP networks that do not support MPLS. GRE and UDP tunnels support MPLS protocol for both IPv4 and IPv6 traffic. You can configure encapsulation and de-encapsulation for the GRE and UDP tunnels.

    To allow the MPLS traffic on the UDP tunnels, include the mpls port-number statement at the [edit forwarding-options tunnels udp port-profile profile-name] hierarchy level. To allow the MPLS traffic on the GRE tunnels, include the mpls statement at the [edit interfaces fti0 unit unit family] hierarchy.

  • Support for layer 3 VPN service over logical tunnel interface (ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7332, ACX7348, and ACX7509)—Starting in Junos OS Evolved Release 24.2R1, we support layer 3 VPN service over logical tunnel interfaces. The feature includes support for :

    • VRF over logical tunnel interface

    • Stitching of layer 3 VPN and layer 2 services through logical tunnel interface

    [See mac-vrf.]

  • Support for logical tunnel physical interface configuration (ACX7024, ACX7024X, ACX7100-32C, ACX7100-48L, ACX7332, ACX7348, and ACX7509)—Starting with Junos Evolved OS Release 24.2R1, ACX7000 routers support logical tunnel physical interface configuration and Layer 2 services over logical tunnel interfaces.

    [See Guidelines for Configuring Logical Tunnels on ACX Series Routers.]

  • Support for configuring GRE tunnel encapsulation and de-encapsulation on flexible tunnel interfaces (ACX7100-32C, ACX7100-48L, ACX7332, ACX7348, ACX7509, ACX7024, and ACX7024X)—Starting in Junos OS Evolved Release 24.2R1, you can configure encapsulation by using the tunnel encapsulation gre source address destination address command at the [edit interfaces fti unit unit] hierarchy level.

    • If you add the tunnel-termination statement at the [edit interfaces fti unit unit tunnel encapsulation gre], it makes the tunnel a de-encapsulation-only tunnel and disables encapsulation.

      The tunnel-termination only mode is not supported.

    • You must specify both the source and destination address if you do not configure the tunnel-termination.

    • You cannot configure a variable prefix mask on the source address.

    • You cannot configure key value.
