How to Change Site-to-Site vpn Static Route to BGP Route

0

I have created a site-to-site vpn with Customer Gateway and a virtual private gateway. We are facing tunnel failure occasionally, so we decide to move BGP routing. So anyone could help with this. Would i need to disassociate that existing Customer Gateway and virtual private gateway in static route site-to-site vpn?

I want to migrate old static route vpn to new bgp route vpn. please anyone give me a full guide for this.

Hello.

I think the answer at the URL below will be helpful.
Your situation is reversed, but what you do is pretty much the same.
https://repost.aws/questions/QUuKuQIvQKTe2GH6c3SdTJlg/vpn-site-to-site-change-from-dynamic-routing-to-static-routing

Create a BGP Site to Site VPN to the same virtual private gateway and link the customer gateway.
Then remove the static route Site to Site VPN.
When deleting a Site to Site VPN with a static route, make sure that the route to the VPC is advertised in BGP before deleting it.

    Very thanks for your response.

    I had created another BGP site-to-site VPN to the same virtual private gateway and link the customer gateway. but can't create the new VPN. It shows an error that "IKEv1 and IKEv2 are already used in the existing site-to-site VPN."

    Do you have any idea about my seanrio?

    Is it an error occurring in the AWS console? Creating a customer gateway for BGP in the AWS Management Console? Existing customer gateways cannot be used because they are already tied to a static Site to Site VPN.

    Yes, while I was creating BGP site-to-site VPN, that error was given. like below "There already exists a VpnConnection with different tunnel option value IKEVersions between customer gateway and VPN gateway. cgw-id: cgw-0bce22146db4366b19, vgw-id: vgw-fe427123c13c18d4, vpn-id: vpn-24np4ff51d26afebb."

    in other hand. i try to create new CGW in same ip and configuration using existing CGW. is doesn't create new CGW it only renams it old CGW name to new name given

    is there any best way to migrate static route vpn to bgp route vpn with minimal downtime.
