Recommended Actions:

If this alarm is not auto-resolved within 10 minutes, then execute the following steps:

1. Navigate to the 'Connected VPC' tab under 'Networking' in NSX manager UI. Please note down the prefix list id and route table Ids for all prefix lists in 'Waiting for Deletion' state.
2. Ask the customer to delete the prefix lists identified in 1 from all route tables identified in 1.
3. Once customer removes all prefix list Ids from all connected VPC route tables, refresh the 'Connected VPC' UI page.
   The entry should no longer be seen.
   If the entry is removed from UI, remediation is done and no more action is required.
