Does anyone have any real world experience of implementing Azure MS expressroute using multiple dedicated circuits, routing private address space over eBGP (private peering) and connecting to public services over eBGP (public peering).
i have a few ideas regarding private peering e.g as your azure environment is seen as an extension of your own network i would probably advertise my internal subnets within a vrf on my external routers and the redistribute into a seperate address-family in BGP, seperating this from the global RT. Id be interested in hearing other ways this can be achieved? Or are there any performance impacts with redistribution of routes?
The public peering seems more of a problem. Does anyone have any practical examples/scenarios of how this would be configured?
thanks
