Anycast IP address in leaf-spine architecure

Hello,

I have a problem with IP Anycast and VXLAN. We configured leaf-spine topology with BGP on default VRF.

Then we added VxLAN between two top of rack vlt switches. The VxLALN is working but only when we add gateway addres in spine switch and add accest to connetc vlan communication from leaf to sine. We have configured Anycast IP Gateway in different VRF. We can ping that address from serwer but can't ping from outside. All other addresses work perfect. How to make it to communicate?

Regards.
