Introduction
There are two types of ExpressRoute connections from Azure to the customer end. One is ExpressRoute Circuit, and the other is the Virtual Network gateway for ExpressRoute. In this article, we will learn how to configure the Azure ExpressRoute gateway. If we need to configure the Gateway, we need the Peer circuit URL and the Authorization key. The circuit owner creates an authorization key and the peer circuit URL from their ExpressRoute circuit, and the authorization is valid for only one connection. If we need to make more connections, each connection requires a separate authorization key.
