  • Support for EVPN-VXLAN on MAC-VRF instances (PTX10001-36MR, PTX10004, and PTX10008) —Starting in Junos OS Evolved Release 21.3R1, you can configure EVPN-VXLAN on MAC-VRF instances only with the following functionalities:

    • VLAN-based service, VLAN bundle service, and VLAN-aware bundle service
    • Configuration of overlapping VLAN IDs across MAC-VRF instances
    • Tunneling encapsulated traffic from locally connected Layer 2 network over a VXLAN tunnel toward the core
    • De-encapsulation of VXLAN traffic from the core and forwarding it to the local L2 network
    • VXLAN overlay with IPv4 underlay network
    • Underlay reachability over ECMP
    • Multihoming of customer edge (CE) devices to multiple provider edge (PE) devices over an Ethernet segment identifier (ESI) interface using active/active configuration
    • Proxy ARP and Network Discovery Protocol (NDP)
    • ECMP
    • IRB interfaces
    • IRB interfaces that can route the multicast packets without IGMP snooping
  • Support for EVPN-MPLS (ACX7100-32C and ACX7100-48L)—Starting in Junos OS Evolved Release 21.3R1, we support the following EVPN-MPLS features on MAC-VRF instances:
    • L2 flooding for broadcast, unknown unicast, and multicast (BUM) traffic
    • Split-horizon between core interfaces
    • Data plane and control plane MAC learning and aging, and static MAC
    • MAC movement and MAC mobility on control plane only
    • MAC limiting and MAC learning
    • Input and output VLAN maps using normalization on user-to-network interfaces (UNIs)
    • Aggregated Ethernet interfaces used for UNIs and network node interfaces (NNIs)
    • Physical interfaces for VLAN tagging, stacked VLAN tagging, flexible VLAN tagging, and extended VLAN bridges using EVPN-MPLS as a service
    • Ethernet bridge mode for logical UNIs
    • VLAN ID lists, and native VLAN ID supported logical UNIs and priority-tagged logical interfaces
    • Underlay with ECMP and FRRouting (FFR)
    • Control-word support for EVPN
    • EVPN Proxy ARP and ARP suppression
