Reference documentation and code samples for the Google Cloud Network Management V1 Client class Cause.

Drop cause types:

Protobuf type google.cloud.networkmanagement.v1.DropInfo.Cause

Cause is unspecified.

Generated from protobuf enum CAUSE_UNSPECIFIED = 0;

Destination external address cannot be resolved to a known target. If the address is used in a Google Cloud project, provide the project ID as test input.

Generated from protobuf enum UNKNOWN_EXTERNAL_ADDRESS = 1;

A Compute Engine instance can only send or receive a packet with a foreign IP address if ip_forward is enabled.

Generated from protobuf enum FOREIGN_IP_DISALLOWED = 2;

Dropped due to a firewall rule, unless allowed due to connection tracking.

Generated from protobuf enum FIREWALL_RULE = 3;

Dropped due to no matching routes.

Generated from protobuf enum NO_ROUTE = 4;

Dropped due to invalid route. Route's next hop is a blackhole.

Generated from protobuf enum ROUTE_BLACKHOLE = 5;

Packet is sent to a wrong (unintended) network. Example: you trace a packet from VM1:Network1 to VM2:Network2, however, the route configured in Network1 sends the packet destined for VM2's IP address to Network3.

Generated from protobuf enum ROUTE_WRONG_NETWORK = 6;

Route's next hop IP address cannot be resolved to a GCP resource.

Generated from protobuf enum ROUTE_NEXT_HOP_FORWARDING_RULE_IP_MISMATCH = 51;

Route's next hop VPN tunnel is down (does not have valid IKE SAs).

Generated from protobuf enum ROUTE_NEXT_HOP_VPN_TUNNEL_NOT_ESTABLISHED = 52;

Route's next hop forwarding rule type is invalid (it's not a forwarding rule of the internal passthrough load balancer).
