Wenn der Status einer der Verbindungen „Kein Signal“ lautet, prüfen Sie noch einmal, ob Sie den entsprechenden Azure-Port wie unter Ports aktivieren beschrieben aktiviert haben.
Routentabelle prüfen
Prüfen Sie in der Routentabelle für Ihre ExpressRoute-Netzwerkverbindung, ob Azure Ihre Google Cloud Routen gelernt hat.
DEVICE_PATH: zum Prüfen der primären Verbindung verwenden Sie primary, zum Prüfen der sekundären Verbindung verwenden Sie secondary
CIRCUIT_NAME: der Name Ihrer ExpressRoute-Netzwerkverbindung
RESOURCE_GROUP: die Ressourcengruppe, die der Netzwerkverbindung zugeordnet ist
Wenn die erwarteten Ergebnisse nicht angezeigt werden, prüfen Sie das von Ihnen erstellte private Peering für Ihre ExpressRoute-Netzwerkverbindung. Versuchen Sie, die Werte für Primäres IPv4-Subnetz und Sekundäres IPv4-Subnetz umzukehren, und prüfen Sie dann noch einmal die Routentabelle.

Google doesn't guarantee that this guidance is up to date or that the sample configuration choices are ideal for your use case. For the most current information, refer to the [Azure documentation](https://learn.microsoft.com/azure/?product=networking).\n\nTo check connectivity between your Google Cloud and Azure networks, complete\nthe following tasks.\n\nCheck for a signal from Azure\n-----------------------------\n\n\nIn Google Cloud, check to see whether your\nCross-Cloud Interconnect port is receiving a signal from the\nExpressRoute Direct port.\n\n### Console\n\n1. In the Google Cloud console, go to the Cloud Interconnect **Physical\n connections** page.\n\n [Go to **Physical\n connections**](https://console.cloud.google.com/hybrid/interconnects/list?tab=interconnects)\n2. Click the name of your primary Cross-Cloud Interconnect connection.\n3. On the **Interconnect details** page, locate the **Link circuit info** table. Check the **Receiving Optical Power** column. This column indicates whether the Cross-Cloud Interconnect connection is receiving input from the Azure port. The value in this column should be **OK**.\n4. Repeat the preceding steps for your redundant Cross-Cloud Interconnect connection.\n\nIf the status of either connection is not receiving a signal, double-check that you enabled\nthe corresponding Azure port, as described in\n[Enable the ports](/network-connectivity/docs/interconnect/how-to/cci/azure/order-azure-ports#enable-ports).\n\nCheck the route table\n---------------------\n\nTo verify that Azure has learned your Google Cloud routes, view the route\ntable for your ExpressRoute circuit. \n\n### Azure PowerShell\n\nUse the [`Get-AzExpressRouteCircuitRouteTable` command](https://learn.microsoft.com/powershell/module/az.network/get-azexpressroutecircuitroutetable?view=azps-8.2.0): \n\n```\nGet-AzExpressRouteCircuitRouteTable -DevicePath DEVICE_PATH `\n -ExpressRouteCircuitName CIRCUIT_NAME `\n -PeeringType AzurePrivatePeering `\n -ResourceGroupName RESOURCE_GROUP\n```\n\nReplace the following:\n\n- \u003cvar translate=\"no\"\u003eDEVICE_PATH\u003c/var\u003e: to check the primary circuit, use `primary`; to check the secondary circuit, use `secondary`\n- \u003cvar translate=\"no\"\u003eCIRCUIT_NAME\u003c/var\u003e: the name of your ExpressRoute circuit\n- \u003cvar translate=\"no\"\u003eRESOURCE_GROUP\u003c/var\u003e: the resource group associated with the circuit\n\nIf you don't see the results that you expect, review the\n[private peering you created](/network-connectivity/docs/interconnect/how-to/cci/azure/configure-azure#set-up-private-peering) for your ExpressRoute circuit. Try reversing the values for\n**IPv4 Primary subnet** and **IPv4 Secondary subnet**, and then check the route table again.\n\nReview the Troubleshooting page\n-------------------------------\n\nFor additional guidance, see\n[Troubleshooting](/network-connectivity/docs/interconnect/support/troubleshooting)."]]
