@Bechir Gharbi ,
Thank you for reaching out.

Based on my understanding of the question, you want to establish a connectivity between your lab environment express route and production environment express route.

I think you can follow this Cross-network connectivity documentation to implement this functionality. Depending on the connectivity you want to establish. You can use Global/Regional Vnet peering to establish connectivity between lab environment vnet and production environment vnet. Virtual Network peering supports connectivity across Azure Active Directory tenants. You can connect your Virtual Networks to the express route circuits by cross connecting VNets to the on-premises networks and then use ExpressRoute Global Reach to establish connectivity between on-premises networks that are connected to different ExpressRoute circuits.

Hope this helps answering your question. Please let me know if you have any additional questions. Thank you!
