A value indicating that the enum field is not set.
CLIENT_IP
value: 345_665_051

5-tuple hash on packet's source and destination IP addresses, IP protocol, and source and destination ports. Connections for the same IP protocol from the same source IP address and port to the same destination IP address and port will be served by the same backend VM while that VM remains healthy. This option cannot be used for HTTP(S) load balancing.
CLIENT_IP_PROTO
value: 25_322_148
3-tuple hash on packet's source and destination IP addresses, and IP protocol.
