Hey You're interpreting the default switch limitation incorrectly.
It doesn't mean the QFX5120 can't support MAC-VRFs, it means even if you implement MAC-VRFs you still only have a single switch domain and can't have overlapping VLANs in the different MAC-VRFs. (MX does not have this limitation. It supports 32k VLANs) IPv6 underlay is supported on QFX5120 in MAC-VRF from Junos 21.2R2: Explore Features by Product | Juniper Networks Pathfinder Feature Explorer <https://apps.juniper.net/feature-explorer/select-platform.html?typ=1&category=Switching&pid=31705120&platform=QFX5120-48Y&swName=Junos%20OS&rel=23.2R1&sid=1277&swtab=Junos%20OS> You can configure an EVPN-VXLAN fabric with an IPv6 underlay. You can use this feature only with MAC-VRF routing instances (all service types). 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. To enable this feature, include these steps when you configure the EVPN underlay: • Configure the underlay VXLAN tunnel endpoint (VTEP) source interface as an IPv6 address: • Even though the underlay uses the IPv6 address family, for BGP handshaking to work in the underlay, you must configure the router ID in the routing instance with an IPv4 address: • Enable the Broadcom VXLAN flexible flow feature, release where the feature is not enabled by default: We support the following EVPN-VXLAN features with an IPv6 underlay: • EVPN Type 1, Type 2, Type 3, Type 4, and Type 5 routes(excluding EX9200 for type 5). • Shared VTEP tunnels (required with MAC-VRF instances). • All-active multihoming, including Ethernet segment ID (ESI) auto-generation and preferencebased DF (DF) election. • EVPN core isolation. • Bridged overlays. • Layer 3 gateway functions in ERB and CRB overlays with IPv4 or IPv6 traffic. • Underlay and overlay load balancing. • Layer 3 protocols over IRB interfaces—BFD, BGP, OSPF. • Data center interconnect (DCI)—over-the-top (OTT) full mesh only. • EVPN proxy ARP and ARP suppression, and proxy NDP and NDP suppression.
