Creates an ExpressRoute circuit authorization.


   -Name <String>
   [-DefaultProfile <IAzureContextContainer>]


The New-AzureRmExpressRouteCircuitAuthorization cmdlet creates a circuit authorization that can be added to an ExpressRoute circuit. ExpressRoute circuits connect your on-premises network to the Microsoft cloud by using a connectivity provider instead of the public Internet. The owner of an ExpressRoute circuit can create as many as 10 authorizations for each circuit; these authorizations generate an authorization key that can be used by a virtual network owner to connect a network to the circuit. There can only one authorization per virtual network.

After you create an ExpressRoute circuit you can use Add-AzureRmExpressRouteCircuitAuthorization to add an authorization to that circuit. Alternatively, you can use New-AzureRmExpressRouteCircuitAuthorization to create an authorization that can be added to a new circuit at the same time the circuit is created.


Example 1: Create a new circuit authorization

$Authorization = New-AzureRmExpressRouteCircuitAuthorization -Name "ContosoCircuitAuthorization"

This command creates a new circuit authorization named ContosoCircuitAuthorization and then stores that object in a variable named $Authorization. Saving the object to a variable is important: although New-AzureRmExpressRouteCircuitAuthorization can create a circuit authorization it cannot add that authorization to a circuit route. Instead, the variable $Authorization is used New-AzureRmExpressRouteCircuit when creating a brand-new ExpressRoute circuit.

For more information, see the documentation for the New-AzureRmExpressRouteCircuit cmdlet.
