EVPN

  • EVPN-VXLAN support with MAC VRF routing instances (QFX5130-32CD)—Starting in Junos OS Evolved Release 21.2R1, QFX5130-32CD switches support EVPN-VXLAN for unicast traffic using MAC virtual routing and forwarding (VRF) routing instances. The switch can be a leaf device or a spine device in an edge-routed bridging or centrally routed bridging overlay design. You can configure multiple EVPN instances (EVIs) of type mac-vrf. Each EVI can support a different EVPN service type (vlan-based, vlan-aware, or vlan-bundle). The switch creates and uses one VTEP logical interface per remote provider edge (PE) device by default, regardless of the number of routing instances. This implementation improves VXLAN VTEP scaling with multiple routing instances.

    EVPN-VXLAN support on this switch includes:

    • EBGP and IBGP overlays
    • Single-homing and all-active multihoming
    • Layer 2 and Layer 3 unicast for IPv4 and IPv6 with ARP suppression
    • Proxy ARP and ARP suppression for Layer 2 and Layer 3 IRB traffic
    • Proxy NDP and NDP suppression for Layer 2 and Layer 3 IRB traffic
    • Service provider style configuration with Q-in-Q support, supported for Layer 2 gateways only and only with MAC VRF vlan-bundle service type
    • Storm control
    • MAC mobility, MAC limiting, MAC move limiting, and duplicate MAC detection
    • Core isolation
    • Proxy re-advertisement of EVPN Type 2 MAC+IP routes by all provider edge devices on the same ESI
    • Virtual machine traffic optimization (VMTO)
    • OSPF and BGP routing protocols on IRB interfaces

  • Support for EVPN Type 5 routes (QFX5130-32CD)—Starting in Junos Evolved OS 21.2R1, the QFX5130-32CD switches support EVPN type 5 routes. EVPN Type 5 routes support inter-subnet routing across datacenters by using IP prefix advertisement.

  • Support for Port Mirroring in EVPN-VXLAN fabrics (QFX5130-32CD)—Starting in Junos Evolved OS 21.2R1, the QFX5130-32CD switches support port mirroring in EVPN-VXLAN fabrics.

  • Firewall filtering and policing (QFX5130-32CD)—Starting in Junos Evolved OS 21.2R1, QFX5130-32CD switches support firewall filtering and policing in EVPN-VXLAN fabrics.
