Explanation

When Cloud VPN uses dynamic routing via BGP, it is the Cloud Router - not the VPN tunnel itself - that manages BGP sessions and advertises routes. In Cloud Logging, Cloud Router activity is captured under the resource type 'gce_router'. Filtering on this type lets you inspect which BGP route advertisements are being sent and received, helping you confirm whether your custom route is actually being advertised to the on-premises peer. The 'vpn_tunnel' and 'vpn_gateway' resource types log tunnel connectivity events (IKE negotiation, tunnel up/down), not BGP routing decisions. 'gce_network_region' is not a valid log resource type for this purpose.
