Additional Features

We've extended support for the following features to these platforms.

  • Hotfix support (ACX7100-32C and ACX7100-48L)—Support for hot fix using a delivery mechanism of full .iso images.

    [See request system software add and show system software list .]

  • IPsec support for OSPFv2 and OSPFv3 (ACX7100-32C, ACX7100-48L, PTX10001-36MR, PTX10003, PTX10008, PTX10016, QFX5130-48C, and QFX5220)

    [See Overview of IPsec, Configuring OSPF Authentication, and Configuring IPsec Security Associations.]

  • Layer 3 Gateway Encapsulation support for Layer 3 over an IPv4 underlay (ACX7100-48L)—Junos OS Evolved Release 21.4R1 provides an L3 gateway that can route packets across subnets. At the ingress VXLAN tunnel endpoint (VTEP), L3 traffic entering from a routing interface is routed to the VXLAN tunnel. At the egress VTEP, the VXLAN tunnel is terminated and the forwarding decision is determined based on the inner header. L3 VXLAN gateways are configurable as both centralized and distributed gateways.

    [See Working with VXLANs.]

  • Metro Ethernet services (ACX7100-32C and ACX7100-48L)

    • IRB interface support for IPv4 and IPv6
    • IPv6 multicast protocol support (FHR, LHR, and RP roles) for any-source multicast (ASM) and source-specific multicast (SSM) modes
      Note:

      Ensure that you enable L3-xl or balanced-exem profile for IPv6 multicast protocol to function.

      [See Multicast Overview and Understanding Integrated Routing and Bridging.]

  • Storm control support in an Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN) overlay network (ACX7100-48L)

    [See Understanding Storm Control.]

  • Support for EVPN-VXLAN Active/Active multihoming with Ethernet Switch Identifier for Link Aggregation Groups (ESI-LAG) (ACX7100-48L)—Junos OS Evolved Release 21.4R1 introduces EVPN control plane support for BGP and VXLAN with VNI (VXLAN Network Identifier) segment ID encoding for L2 and L3 gateway unicast functionality. This feature supports Active/Active multihoming for servers and nodes connecting to multiple leaf nodes. You can configure multihomed Ethernet segments configured on the physical interface (IFD).

    [See EVPN VXLAN User Guide - Leaf Device Forwarding.]

  • Supported transceivers, optical interfaces, and DAC cables (ACX Series, PTX Series, and QFX Series)—Select your product in the Hardware Compatibility Tool to view supported transceivers, optical interfaces, and DAC cables for your platform or interface module. We update the HCT and provide the first supported release information when the optic becomes available.

  • VXLAN Layer 2 gateway with encapsulation support over an IPv4 underlay (ACX7100-48L)—Junos OS Evolved Release 21.4R1 includes VXLAN L2 gateways that provide L2 connectivity between leaf devices separated by an underlay Layer 3 network.

    Note:

    The CLI command set protocols evpn default-gateway no-gateway-community is a required configuration.
