The Add-AzExpressRouteCircuitAuthorization cmdlet adds an authorization 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 his or her network to the
circuit (one authorization per virtual network). Add-AzExpressRouteCircuitAuthorization
adds a new authorization to a circuit and, at the same time, generates the corresponding
authorization key. These keys can be viewed at any time by running the
Get-AzExpressRouteCircuitAuthorization cmdlet and, as needed, can then be copied and forwarded
to the appropriate network owner.
Note that, after running Add-AzExpressRouteCircuitAuthorization, you must call the
Set-AzExpressRouteCircuit cmdlet to activate the key. If you do not call
Set-AzExpressRouteCircuit the authorization will be added to the circuit but will not be
enabled for use.
Examples
Example 1: Add an authorization to the specified ExpressRoute circuit
The commands in this example add a new authorization to an existing ExpressRoute circuit. The first
command uses Get-AzExpressRouteCircuit to create an object reference to a circuit named
ContosoCircuit. That object reference is stored in a variable named $Circuit.
In the second command, the Add-AzExpressRouteCircuitAuthorization cmdlet is used to add a
new authorization (ContosoCircuitAuthorization) to the ExpressRoute circuit. This command adds the
authorization but does not activate that authorization. Activating an authorization requires the
Set-AzExpressRouteCircuit shown in the final command in the example.
