Explanation

When you create an ExpressRoute circuit in the Azure portal, Azure generates a unique service key (also called a circuit key) for that circuit. This key is the identifier you hand to your ExpressRoute service provider so they can provision the circuit on their side and link it to your Azure resource. IKEv2 shared keys and certificates are used for IPsec/VPN connections, not ExpressRoute. Public IP addresses are not required by the provider for circuit provisioning. The service key is the single piece of information the provider needs.
