The external VPN gateway has four public IP addresses; at the time of writing this API, the AWS virtual private gateway is an example which has four public IP addresses for high availability connections; there should be two VPN connections in the AWS virtual private gateway , each AWS VPN connection has two public IP addresses; please make sure to put two public IP addresses from one AWS VPN connection into interfaces 0 and 1 of this external VPN gateway, and put the other two public IP addresses from another AWS VPN connection into interfaces 2 and 3 of this external VPN gateway. When displaying highly available configuration status for the VPN tunnels connected to FOUR_IPS_REDUNDANCY external VPN gateway, Google will always detect whether interfaces 0 and 1 are connected on one interface of HA Cloud VPN gateway, and detect whether interfaces 2 and 3 are connected to another interface of the HA Cloud VPN gateway.
SingleIpInternallyRedundant
The external VPN gateway has only one public IP address which internally provide redundancy or failover.
TwoIpsRedundancy
The external VPN gateway has two public IP addresses which are redundant with each other, the following two types of setup on your on-premises side would have this type of redundancy: (1) Two separate on-premises gateways, each with one public IP address, the two on-premises gateways are redundant with each other. (2) A single on-premise gateway with two public IP addresses that are redundant with eatch other.
UndefinedRedundancyType
A value indicating that the enum field is not set.
