Hi Laz,

Thank you for taking the time to share your insights and high-level guidelines for the migration. I truly appreciate your input on defining the underlying architecture, selecting the right underlay/overlay technologies, and maintaining a clean L3 handoff during the transition from Arista to Juniper fabrics.

Your guidance gives me a clearer starting point for planning this project, and I value your expertise.

Best regards,  
Raju
