For the QFX5110 specifically, MAC-VRF is supported: https://apps.juniper.net/feature-explorer/feature-info.html?fKey=9788&fn=MAC+VRF+with+EVPN-VXLAN
But IPv6 underlay is not: https://apps.juniper.net/feature-explorer/feature-info.html?fKey=11165&fn=EVPN-VXLAN+fabric+with+an+IPv6+underlay So maybe it's an ASIC limitation as QFX5110 is using Trident 2+ and QFX5120/EX4400 is using Trident 3.
