Which of the below mentioned answers is not required to setup this configuration?
The type of customer gateway, such as Cisco ASA, Juniper J-Series, Juniper SSG, Yamaha.
Elastic IP ranges that the organization wants to advertise over the VPN connection to the VPC.
Internet-routable IP address (static) of the customer gateway’s external interface.
Border Gateway Protocol (BGP) Autonomous System Number (ASN) of the customer gateway.
Explanations:
The type of customer gateway is required as AWS needs this to support compatible device configurations.
Elastic IP ranges to advertise are not necessary for setting up the VPN connection; only the external IP is needed.
The internet-routable IP of the customer gateway is needed to establish the VPN connection.
The BGP ASN of the customer gateway is necessary for dynamic routing in a VPN connection setup.
From my point of view, the answer is:
Elastic IP ranges that the organization wants to advertise over the VPN connection to the VPC.
