 Azure Route Server simplifies the exchange of routing information between any Network Virtual Appliance (NVA) that supports the Border Gateway Protocol (BGP) routing protocol and the Azure Software Defined Network (SDN) in the Azure Virtual Network (VNet) without the need to manually configure or maintain route tables. With the support for Next Hop IP in Azure Route Server, you can peer with NVAs deployed behind an Azure Internal Load Balancer (ILB). The internal load balancer lets you set up active-passive connectivity scenarios and leverage load balancing to improve connectivity performance.
