Azure doesn’t allow any hosted VM to participate in BGP, or any dynamic routing with the local vswitch. A common scenario is for enterprises to use ExpressRoute to access their Azure virtual networks (VNets) containing their own private IP addresses. We will accept default routes on the private peering link only. Once it is completed, the connection status retrieved via the Get L2 Connection {uuid} API should change from “Pending-BGP-Peering” to “Provisioned” Alternatively, you can also synchronize the peering using the Equinix portal.
