Viewing Overlay Routes

Contrail Networking Controller peers with Multi-Protocol BGP (MP-BGP) routers with both data center devices, such as underlay switches (leaf and spine), as well as SDN gateways. The controller receives and advertises the routes through control nodes. Starting with Contrail Networking Release 1910, you can view, filter and search the overlay MP-BGP routes on Contrail Command.

Being able to view control node data enables you to debug and troubleshoot networking issues.

To view the overlay routes, perform the following steps.

  • Navigate to the Infrastructure > Cluster page. The Overview tab is displayed with an overview of the cluster infrastructure components, including the numbers of control nodes, compute nodes, analytics nodes, config nodes, and database nodes currently operational and also virtual networks. You can also view charts displaying config nodes response sizes against response time as well as analytics message sizes against time.
  • Click Cluster Nodes to view more details on each of these nodes. The Cluster Name Nodes page appears with lists of control nodes, compute nodes, service nodes, multicloud gateway nodes, and baremetal servers in their separate respective tabs.
  • To view more details on control nodes, select a control node on the Control Nodes tab. The Control_Node Details page appears.
  • The Control_Node Details page has multiple tabs.

    • The Summary tab provides a summary of the status and activity on the selected node. It also displays charts detailing host CPU usage, memory usage, and so on. In the Contrail Web UI, similar information was available under Monitor > Infrastructure > Control Nodes > Summary. However, Contrail Command displays more details since it uses Contrail Insights to generate the data.

    • Click the Peers tab to view information about peers established for this control node. The Peers tab displays the peers for an individual control node and their peering state. Click the ▸ icon next to the peer name to expand, view, and copy peer information. You can use the search field on the top right of the page to search for peers based on specified input strings.

    • Click the Routes tab to view information on the routes. The Routes tab displays active routes for this control node and lets you query the results. Click the filter icon on the top right of the page to apply filters while searching for routes. You can also apply multiple filters.

    • Click the Alarms tab to view all alarms on the control node. Click the ▸ icon next to the alarm name to expand and view alarm details.
