AWS Certified Advanced Networking - Specialty (#6)

A corporate network routing table contains 624 individual RFC 1918 and public IP prefixes. You have two AWS Direct Connect connectors. You con?gure a private virtual interface on both connections to a virtual private gateway. The virtual private gateway is not currently attached to a VPC. Neither BGP session will maintain the

Established

state on the customer router. The AWS Management Console reports the private virtual interfaces as

Down.

What could you do to address the problem so that the AWS Management Console reports the private virtual interface as

Available

?

Attach the virtual private gateway to a VPC and enable route propagation.
Filter the public IP pre?xes on the corporate network from the private virtual interface.
Change the BGP advertisements from the corporate network to only be a default route.
Attach the second virtual interface to an alternative virtual private gateway.
