Reconfigure Static Tunnels

Contrail Service Orchestration (CSO) creates static overlay tunnels between a branch site and an enterprise hub site or between two enterprise hub sites, based on matching mesh tags associated with the WAN link.

If you modify the mesh tags for a WAN link while editing a branch or an enterprise hub site, the existing static tunnels are not updated. To apply the changes that you made to the WAN link, you must manually reconfigure the static tunnels.

Note:

  • To reconfigure the static tunnels associated with a provider hub site, you must edit the site and update the overlay tunnel information in the Connects to Hubs (Overlay Tunnel Type and Overlay Peer Interface) fields.

  • We recommend that you reconfigure the static tunnels during a downtime or when traffic between the sites is not expected because reconfiguring the existing static tunnels can result in connectivity loss between the sites in the tenant.

A Tenant Administrator user can reconfigure static tunnels between a branch site and an enterprise hub site or between two enterprise hub sites in the Customer Portal.

To reconfigure static tunnels for a site:

  1. Click Resources > Site Management.

    The Site Management page appears.

  2. Click the Site-Name link of the site for which you want to reconfigure the static tunnels.

    The Site-Name page appears.

  3. On the WAN tab, click Reconfigure.

    The Reconfigure Static Tunnel page appears.

  4. In the Destination Name list, enter or select the names of one or more destination sites for which you want to reconfigure the static tunnels.
  5. Click OK to save the changes.

    A Reconfigure Static Tunnel job is triggered and you are returned to the Site-Name page. You can click the job link to view details of the job (including job status, start date and time, and end date and time). Alternatively, you can view the status of the job on the Jobs (Monitor > Jobs) page.

    After the job completes successfully, the static tunnels are reconfigured between the source and the destination sites that you selected. On the WAN tab of Site-Name page, the overlay topology graphic is updated with the reconfigured static tunnels.

    If the Reconfigure Static Tunnel job fails, you can retry the failed job from the Jobs page or attempt to reconfigure the static links again.
