Jun 1, 2025June 2025 monthly summary for vexxhost/atmosphere focused on stabilizing OVN-based baremetal VLAN networking. Delivered a critical connectivity fix to ensure consistent communication between baremetal VLAN ports and their default gateway by binding the internal router port of the VLAN network to the same HA chassis group as the network, mirroring the external router port behavior. This patch reduces VLAN connectivity issues in targeted OVN configurations and improves overall network uptime.
