Can invalid routing entries in Cloud Network be deleted?

Yes, invalid routing entries in a cloud network can typically be deleted to maintain network efficiency and security.

Explanation:
Routing entries in a cloud network define how traffic is forwarded between subnets, virtual machines, or external networks. Over time, some entries may become outdated, incorrect, or redundant due to changes in network architecture, decommissioned resources, or misconfigurations. These invalid entries can cause routing loops, traffic blackholes, or security vulnerabilities.

Example:
Suppose a cloud network has a static route directing traffic to a decommissioned virtual machine (VM). This route is no longer valid because the VM no longer exists. If left unchecked, traffic intended for that VM may be misrouted or dropped. Deleting this invalid route ensures traffic is correctly forwarded to active destinations.

Recommended Tencent Cloud Service:
In Tencent Cloud, you can manage and delete invalid routing entries using the Virtual Private Cloud (VPC) service. Specifically:

• Navigate to the VPC Console.
• Go to Route Tables under the relevant VPC.
• Identify and delete outdated or incorrect routes manually.
• For automated route management, consider using Route Table Policies or integrating with Tencent Cloud Network Security Services to detect and clean up invalid configurations.

This ensures your cloud network remains optimized and secure.
