Hi! I have full Arista VXLAN network with CVX as a controller with “service vxlan” and BGP EVPN between different CVX for DCI. Now I need to interconnect another vendor leaf switches to CVX via BGP EVPN. And got a problem. When I recive mac-ip route from other CVX via EVPN, then advertise this route to “service vxlan” is great work, but when I recive mac-ip route from other vendors then this route don’t advertise to “service vxlan”.

Route wich I recive from other CVX and work:
CVX-1(config)#show bgp neighbors 10.102.0.2 evpn received-routes route-type mac-ip fa16.3e6b.aa20 detail
BGP routing table information for VRF default
Router identifier 10.32.0.6, local AS number 65002
BGP routing table entry for mac-ip 1200001 fa16.3e6b.aa20, Route Distinguisher: 100:100
Paths: 1 available
65202
10.34.0.5 from 10.102.0.2 (10.34.0.4)
Origin IGP, metric -, localpref -, weight 0, valid, external, best
Extended Community: Route-Target-AS:100:100 TunnelEncap:tunnelTypeVxlan EvpnMacMobility:1
VNI: 1200001 ESI: 0000:0000:0000:0000:0000

Route wich I recive from antoher vendor switch and don’t work:
CVX-1(config)#show bgp neighbors 10.32.0.20 evpn received-routes route-type mac-ip detail
BGP routing table information for VRF default
Router identifier 10.32.0.6, local AS number 65002
BGP routing table entry for mac-ip 4c5e.0c66.e450, Route Distinguisher: 100:100
Paths: 1 available
65011
10.32.0.21 from 10.32.0.20 (10.32.0.20)
Origin INCOMPLETE, metric 0, localpref -, weight 0, valid, external, best
Extended Community: Route-Target-AS:100:100 TunnelEncap:tunnelTypeVxlan
VNI: 3000036 ESI: 0000:0000:0000:0000:0000

I think that happend because another vendor switch don’t advertise VNI in mac-ip. How can I to ask CVX don’t use VNI in mac-ip and use VNI from VNI field? Or may be proble is other?
