Hello,
We have 8 data centers sites across the world with central one. All sites in interconnected with a Layer 3 DCI and each running iBGP protocol with tunnel interfaces on ISR routers. But as the new sites is emerging i feel that's getting more and more complicated to manage the routing policies to each one. (Because the iBGP doesnt consider as-path in metrics calculation). im thinking to change all sites to eBGP with private AS numbers. Maybe you'd have some advices on running BGP overlay network ?
Thank you
