The clarification is helpful. Virtual Cisco 8000 (VXR) is designed for testing routing and control-plane features, not physical optics or QSFP transceivers. At Jackwin Safety, we appreciate practical explanations like this because they help engineers...

Thanks for sharing the detailed changelog. It's great to see so many bug fixes and stability improvements in this release. Community feedback on real-world performance after upgrading is especially valuable for anyone planning their deployment.

Thanks for the update and for resolving the issue. It's helpful to know the root cause was identified, and this information will definitely assist others who encounter the same connectivity problem.

This looks like a service startup timeout during the Cisco DNA Center upgrade. Reviewing the service logs and verifying system resources, package compatibility, and cluster health should help identify the root cause. Hope you get it resolved soon!

A very informative discussion that clearly explains router visibility and traceroute behavior.
