You can run Remote Diagnostics tests to view the logs of the BGP sessions and use the log information for troubleshooting purposes.

To run the tests for BGP:

  1. In the SD-WAN service of the Enterprise Portal, click Diagnostics > Remote Diagnostics.
  2. The Remote Diagnostics page displays all the active Edges.
  3. Select the Edge that you want to troubleshoot. The Edge enters live mode and displays all the possible Remote Diagnostics tests than you can run on the Edge.
  4. For troubleshooting BGP sessions, scroll to the following sections and run the tests:
    • Troubleshoot BGP - List BGP Redistributed Routes – Run this test to view routes redistributed to BGP neighbors.
    • Troubleshoot BGP - List BGP Routes – Run this test to view the BGP routes from neighbors. You can enter IPv4 or IPv6 prefix to view specific BGP routes or leave the prefix empty to view all the BGP routes.
