> Hello,

> I am trying to make work EVPN-VXLAN with an IPv6 (eBGP) underlay between a
> couple of QFX5110 with JunOS version 22.2R3 (following
> https://www.juniper.net/documentation/us/en/software/junos/evpn-vxlan/topics/topic-map/vxlan-ipv6-underlay-overview.html)
> When I check the status, it seems everything is working as expected (I can see
> routes and MACs in to the VRF table on both side). But I cannot ping from one
> client device on side A to another one on side B.
> The routing table shows the MAC and IPv4 are learned on both side but it seems
> no traffic reaches the client devices (arp table on client device shows the
> remote device is "incomplete").
> 
> Can you give a clue ? I haven't found any information on wether it could work on
> QFX5110.
> Maybe you could share a working config ?

> Thank you in advance,
