Hi all, I've setup ExpressRoute circuit that link my Azure networks with my on-prem lan.
Every vNET that I attach to ExpressRoute is propagated with BGP so device on-prem can reach it.

I need to propagate now also the default route 0.0.0.0 so routers on my sites redirect all traffic to Azure (now the default route is to HQ), provider tell us that he takes all networks from Azure and cannot add manually this defualt.
So it there any way to force the propagation from Azure of 0.0.0.0 to ExpressRoute so all my network on-prem go through Azure?

Thanks.

NOTE: traffic with defined network works well to and from Azure but I cannot found a way to add 0.0.0.0
