Pull request overview

This PR extends the Az.Network module’s Route Server peer and Virtual Network Gateway connection cmdlets/models to support RoutingConfiguration, aligning Azure PowerShell with the referenced swagger updates.

Changes:

• Added -RoutingConfiguration support to New-AzVirtualNetworkGatewayConnection and Set-AzVirtualNetworkGatewayConnection.
• Added -RoutingConfiguration plus hub vnet connection association parameters to Add-AzRouteServerPeer and Update-AzRouteServerPeer, and surfaced the corresponding properties on returned objects.
• Updated help docs, changelog, and scenario tests for the new capabilities.

src/Network/Network/Cortex/VHubRouteTable/NewAzureRmRoutingConfigurationCommand.cs:81

• If the user supplies -AssociatedRouteTable and it cannot be resolved, the cmdlet currently proceeds with a null AssociatedRouteTable, silently ignoring invalid input. This makes typos or bad IDs hard to detect and can lead to unexpected routing configuration objects.

Consider throwing when AssociatedRouteTable is non-empty but ResolveRouteTableId returns null (while still allowing AssociatedRouteTable to be omitted entirely).

            PSVHubRouteTable associatedRouteTable = null;
            if (!string.IsNullOrWhiteSpace(AssociatedRouteTable))
            {
                associatedRouteTable = ResolveRouteTableId(AssociatedRouteTable);
            }

src/Network/Network.Test/ScenarioTests/RouteServerTests.ps1:402

• The assertions reference $peer.HubVnetConnectionReference, but the model exposed by this PR is HubVirtualNetworkConnection (see PSRouteServerPeer/PSBgpConnection). These assertions will fail because HubVnetConnectionReference is not a property on the returned object.

        Assert-AreEqual "65011" $peer.PeerAsn
        Assert-NotNull $peer.HubVnetConnectionReference
        Assert-AreEqual $peer.HubVnetConnectionReference.Id $hubVnetConnection.Id

• Same issue in the SetByResourceId syntax block: -AcquirePolicyToken / -ChangeReference are not listed in SYNTAX, but the file still contains a -ChangeReference parameter section. Please keep SYNTAX consistent with the documented parameters.

 [-GatewayCustomBgpIpAddress <PSGatewayCustomBgpIpConfiguration[]>] [-AuthenticationType <String>]
 [-CertificateAuthentication <PSCertificateAuthentication>] [-AsJob] [-ExpressRouteGatewayBypass]
 [-EnablePrivateLinkFastPath] [-RoutingConfiguration <PSRoutingConfiguration>]
 [-DefaultProfile <IAzureContextContainer>]
 [-WhatIf] [-Confirm] [<CommonParameters>]

src/Network/Network/help/Update-AzRouteServerPeer.md:28

• Same inconsistency in the RouteServerNPeerNameParameterSet SYNTAX block: it lists the new parameters but omits -AcquirePolicyToken / -ChangeReference while the file still documents them (and another parameter set lists them).
