* Specifies whether fast IP move is enabled, and if so, the mechanism to achieve it. Supported
* values are: - DISABLED: Fast IP Move is disabled. You can only use the haPolicy.leader API to
* update the leader. - >GARP_RA: Provides a method to very quickly define a new network endpoint
* as the leader. This method is faster than updating the leader using the haPolicy.leader API.
* Fast IP move works as follows: The VM hosting the network endpoint that should become the new
* leader sends either a Gratuitous ARP (GARP) packet (IPv4) or an ICMPv6 Router Advertisement(RA)
* packet (IPv6). Google Cloud immediately but temporarily associates the forwarding rule IP
* address with that VM, and both new and in-flight packets are quickly delivered to that VM. Note
* the important properties of the Fast IP Move functionality: - The GARP/RA-initiated re-routing
* stays active for approximately 20 minutes. After triggering fast failover, you must also
* appropriately set the haPolicy.leader. - The new leader instance should continue to send
* GARP/RA packets periodically every 10 seconds until at least 10 minutes after updating the
* haPolicy.leader (but stop immediately if it is no longer the leader). - After triggering a fast
* failover, we recommend that you wait at least 3 seconds before sending another GARP/RA packet
* from a different VM instance to avoid race conditions. - Don't send GARP/RA packets from
* different VM instances at the same time. If multiple instances continue to send GARP/RA
* packets, traffic might be routed to different destinations in an alternating order. This
* condition ceases when a single instance issues a GARP/RA packet. - The GARP/RA request always
* takes priority over the leader API. Using the haPolicy.leader API to change the leader to a
* different instance will have no effect until the GARP/RA request becomes inactive. - The
* GARP/RA packets should follow the GARP/RA Packet Specifications.. - When multiple forwarding
* rules refer to a regional backend service, you need only send a GARP or RA packet for a single
* forwarding rule virtual IP. The virtual IPs for all forwarding rules targeting the same backend
* service will also be moved to the sender of the GARP or RA packet. The following are the Fast
* IP Move limitations (that is, when fastIPMove is not DISABLED): - Multiple forwarding rules
* cannot use the same IP address if one of them refers to a regional backend service with
* fastIPMove. - The regional backend service must set the network field, and all NEGs must belong
* to that network. However, individual NEGs can belong to different subnetworks of that network.
* - The maximum number of network endpoints across all backends of a backend service with
* fastIPMove is 64. - The maximum number of backend services with fastIPMove that can have the
* same network endpoint attached to one of its backends is 64. - The maximum number of backend
* services with fastIPMove in a VPC in a region is 64. - The network endpoints that are attached
* to a backend of a backend service with fastIPMove cannot resolve to C3 machines. - Traffic
* directed to the leader by a static route next hop will not be redirected to a new leader by
* fast failover. Such traffic will only be redirected once an haPolicy.leader update has taken
* effect. Only traffic to the forwarding rule's virtual IP will be redirected to a new leader by
* fast failover. haPolicy.fastIPMove can be set only at backend service creation time. Once set,
* it cannot be updated. By default, fastIpMove is set to DISABLED.
* The value may be {@code null}.
