Troubleshooting Routing Issues in Your Aviatrix-Managed Network

This section describes the Cloud Routes feature of Aviatrix CoPilot.

In Cloud Routes, you can view all routing information for managed resources spanning your Aviatrix transit network, including resources across clouds (multicloud) and on-prem (for external/Site2Cloud connections). For multicloud, cloud engineers can view the information in a central place without having to log in to individual cloud provider consoles.

Working with Cloud Routes

This section describes the Cloud Routes feature of Aviatrix CoPilot.

You access Cloud Routes in CoPilot by going to CoPilot > Diagnostics > Cloud Routes or typing Cloud Routes in the navigation search.

In Cloud Routes, you can view all routing information for managed resources spanning your Aviatrix transit network, including resources across clouds (multicloud) and on-prem (for external/Site2Cloud connections). For multicloud, cloud engineers can view the information in a central place without having to log in to individual cloud provider consoles.

In Cloud Routes, you can view routing information for:

  • Gateway Routes: Tunnel information for all Aviatrix gateways managed by the Controller across clouds.

    You can view the detailed routing table of each gateway, the state (up or down status) of the route (tunnel/interface), and more detailed information.

    You can filter routes based on gateway name to view the routing table of that specific gateway.

    You can filter routes based on a specific subnet to view all gateways across which the subnet is propagated.

    You can filter routes based on a specific IP address to view all gateways across which a subnet is propagated that includes the specific IP address.

  • VPC/VNet/VCN Routes: Routing tables for all VPC/VNet/VCNs in any cloud provider.

    You can filter routing tables based on a specific route table name.

    You can filter routing tables based on a specific subnet to view all routes across which the subnet is propagated.

    You can filter routing tables based on a specific IP address to view all routes across which a subnet is propagated that includes the specific IP address.

  • External Connections (Site2Cloud): Data center connections into the cloud.

    You can view the tunnel status and the gateway to which it is connected.

    You can view the remote IP address and the type of tunnel.

  • BGP Info: BGP connections from on-prem into the cloud.

    You can view advertised routes being sent to the remote site, learned routes that are being received from the remote site, and a map showing how the BGP connection is connected. The map shows the gateway the BGP connection is established on, the local ASN and IP, the connection name you defined, the remote ASN IP and the remote ASN.

Performing Diagnostics from Cloud Routes

You can run diagnostics from Aviatrix gateways running in your multicloud network directly from Cloud Routes. Performing diagnostics from Cloud Routes can dramatically reduce the time spent troubleshooting issues. You can also run diagnostics from gateways directly from Topology (Topology V1).

To perform diagnostics from Cloud Routes, use the following steps:

  1. In CoPilot, go to Home > Diagnostics > Cloud Routes, and then click on the Gateway Routes tab.

  2. In the Gateway Routes view, locate the gateway from which you want to run diagnostics, and click the Gateway Diagnostics icon in its table row.

  3. Perform any of the following diagnostic tasks for the gateway:

    1. PING: Run pings directly from the gateway to outside the Aviatrix managed network or to any resource inside the network.

    2. TRACEROUTE: Run trace route.

    3. TRACEPATH: Discover the MTU on the path if router supports it.

    4. TRACELOG: Upload a gateway’s tracelog directly to Aviatrix Support. The controller and gateway tracelog is uploaded and the support team notified.

    5. Test Connectivity: Test the connectivity of the gateway to a specified host running on a specified TCP or UDP port.

    6. ACTIVE SESSIONS: View sessions that are active on the selected gateway. You can filter active sessions by search criteria. For example, a search on a specific port to see if the gateway has an action session on that port.

    7. INTERFACE STATS: View interface statistics about the gateway. The number of interfaces or tunnels associated with the gateway is displayed. Click on the name of an interface or tunnel to see its statistical information.

    8. PACKET CAPTURE: Capture packets on any gateway. Filter on host and port number and specify the capture time. Search and filter by time, source address, destination address, source port, destination port, protocol, flags, length, and info. Select the interface on the physical or virtual interface you want to capture on. Click Start to start the capture, click Stop to stop the capture, then click Download to download the pcap file. The pcap file can be viewed by Wireshark.

    9. SERVICE ACTIONS: Check the status of gateway services and restart services.
