Can one dedicated physical line access multiple VPCs?

One dedicated physical line can access multiple VPCs in a single resource pool. After creating a dedicated physical line and a CDA gateway and adding a client-side route, select the CDA Gateway Details > VPC. On the page that is displayed, add multiple VPCs by repeating the operation of adding a VPC, so as to access multiple VPCs through one dedicated physical line.

Can CDA connect to VPCs across accounts?

At present, CDA can only connect to VPCs under the current account. When adding a VPC, you can select only a created VPC instance under your account. The capability of connecting to VPC instances across accounts through a CDA is currently being planned. Stay tuned.

Can CDA connect to VPCs in different resource pools?

At present, CDA can only connect toVPCs in a single resource pool. When adding a VPC, you can select only a created VPC instance in the resource pool of a dedicated physical line and CDA gateway.

Which access modes does CDA support?

When a dedicated physical line is deployed, CDA supports access through an aggregate port or a physical port of a switch.

CDA supports access through an exclusive port. A user can exclusively occupy a dedicated physical line, which makes services more secure and stable.

CDA supports access through a shared port. Multiple users share one dedicated physical line and user data is logically isolated, which can help save user costs while ensuring service security.

Does CDA support dynamic routing protocols?

At present, CDA supports the dynamic routing protocol BGP. One dedicated physical line can be configured with only one BGP dynamic route or multiple static routes. You can select CDA Gateway Details > Client-side Route in the eSurfing Cloud console and directly add a static route on the page that is displayed.
