EVPN

  • EVPN-VXLAN fabric with an IPv6 underlay (QFX5120-32C, QFX5120-48T, QFX5120-48Y, QFX10002, QFX10008, and QFX10016)—Starting in Junos OS Release 21.2R2, you can configure an EVPN-VXLAN fabric with an IPv6 underlay. To enable this feature, configure the VTEP source interface in an EVPN MAC-VRF routing instance as an IPv6 address. You can configure this feature only with MAC-VRF routing instances (any service type). You must configure either an IPv4 or an IPv6 underlay across the EVPN instances in the fabric. You can’t mix IPv4 and IPv6 underlays in the same fabric.

    With an IPv6 underlay, we support many of the EVPN-VXLAN features that we support with an IPv4 underlay. We don't support the following EVPN-VXLAN features with an IPv6 underlay:

    • Multicast optimization features

    • Multicast protocols in centrally routed bridging (CRB) architectures

    • PIM distributed designated router on EVPN IRB interfaces

    • Data Center Interconnect (DCI)

    • MAC filtering and BPDU block

    • Filtering and policing on the QFX10000 line of switches

    • Port mirroring

    • sFlow

  • DHCP relay in an EVPN-VXLAN fabric with an IPv6 underlay (QFX5120, QFX10002, QFX10008, and QFX10016)—Starting in Junos OS Release 21.2R2, EVPN-VXLAN fabrics with an IPv6 underlay support DHCP relay. You can configure the DHCP relay agent on the spine devices in centrally routed and edge-routed bridging overlays. Support for DHCP relay includes DHCPv4 and DHCPv6.

  • Port mirroring and analyzers in an EVPN-VXLAN fabric with an IPv6 underlay (QFX5120)—Starting in Junos OS Release 21.2R2, you can configure port mirroring and analyzers on QFX5120 switches in an EVPN-VXLAN fabric with an IPv6 underlay. Port mirroring sends copies of all packets or policy-based sample packets to local or remote analyzers where you can monitor and analyze the data.

    [See Port Mirroring and Analyzers.]

  • Support for storm control, MAC filtering, and BPDU protection in EVPN-VXLAN with IPv6 underlay (QFX5120)—Starting in Junos OS Release 21.2R2, QFX5120 switches set up for EVPN-VXLAN with an IPv6underlay support storm control for ingress traffic on Ethernet switching interfaces that are part of the EVPN-VXLAN instance. These switches also support bridge protocol data units (BPDUs) and user-defined profiles for broadcast, unknown unicast, and multicast (BUM) traffic. Firewall filter-based MAC filtering is also supported with the following match conditions: source and destination MAC addresses, source and destination ports, user VLAN ID, EtherType, and IP protocol.

  • Support for firewall filters on EVPN-VXLAN with IPv6 underlays (QFX5120-32C, QFX5120-48T, QFX5120-48Y, and QFX5120-48YM)—Starting in Junos Release 21.2R2, QFX5120 switches support firewall filters for ingress and egress traffic on EVPN-VXLAN with IPv6 underlays.

  • Seamless EVPN-VXLAN stitching with MAC-VRF routing instances (QFX10002, QFX10008, and QFX10016)—Starting in Junos OS Release 21.2R2, we support seamless stitching of unicast routes across EVPN-VXLAN data centers through a WAN using MAC-VRF routing instances. You can use this feature between data centers (Data Center Interconnect [DCI]) or between points of delivery (PODs) within a data center. The EVPN control plane stitches the EVPN routes from the PODs or data centers and the WAN into a single customer-specific MAC forwarding table.

    On each interconnection device, configure:

    • A customer-specific EVPN instance (EVI) of type mac-vrf.

    • Elements in the [edit routing-instances name protocols evpn interconnect] hierarchy in the EVI to enable the interconnection.
