Fabric VXLAN and Basic MPLS VPN

Hi everyone,

I hope you are doing well...

I am writing to you in order to solve a problem of network architecture (FABRIC VXLAN & MPLS)  
You will find below details of this network architecture   
- 2x SPINEs : N9K-C9332C, NXOS: version 9.3(4)   
- 2x LEAFs  : N9K-C93180YC-EX, NXOS: version 9.3(4)   
- 2x BorderLEAFs-PE : N7K-C7004, NXOS: version 8.4(1) with N7K-F312FQ-25 to connect MPLS and VxLAN. This N7K is shared between the new VXLAN FABRIC architecture and our MPLS backbone (vpnv4).

The Fabric VxLAN works perfecty well (Routes BGP L2VPN EVPN between VRFs, NVE PEERs, Routing inter-vlan, ...) with all LEAFs and BorderLEAFs.

The problem is the N7K (BorderLEAF) between MPLS and BorderLEAFs, the old routes BGP vpnv4 stop to be advertised and the routes BGP L2VPN EVPN start to be advertised, when we start using the "feature fabric forwarding".
Is there an issue with "feature fabric forwarding" ?


Thank you for helping me.

regards,
CR
