After an Express Connect circuit is enabled, you must create a virtual border router (VBR) for the Express Connect circuit. The VBR is used to route traffic between the virtual private cloud (VPC) and the data center that are connected through the Express Connect circuit.
Background information
A VBR is a router deployed between a VPC and customer-premises equipment (CPE) in
a data center. Each VBR is associated with a route table. You can add routes to the
route table of a VBR to control network traffic forwarding. A VBR provides the following
features:
- Exchanges data between a VPC and a data center.
- Determines the type of virtual interface of an Express Connect circuit: Layer 3 router
interface or Layer 3 Virtual Local Area Network (VLAN) subinterface.
Adds or identifies VLAN tags if a Layer 3 VLAN subinterface is used.
- Supports Border Gateway Protocol (BGP) routing.
Create a VBR
Purchase VBRs after the free VBR quota is exhausted
When your free VBR quota is exhausted, you can choose to purchase VBRs.
Note Before you purchase VBRs for your account, you must Submit a ticket to acquire the permissions.
Modify the maximum bandwidth of a VBR
You can modify the maximum bandwidth of a free VBR.
- Log on to the Express Connect console.
- In the top navigation bar, select the region and click Exclusive Physical Connection in the left-side navigation pane.
- On the Exclusive Physical Connection page, click the ID of the Express Connect circuit.
- On the details page of the Express Connect circuit that you want to manage, choose Actions column. in the
- In the Bandwidth Settings panel, specify Bandwidth Cap and click OK.
Modify the configuration of a VBR
Delete a VBR
You can delete VBRs that you no longer need.
- Log on to the Express Connect console.
- In the top navigation bar, select the region and click Virtual Border Routers (VBRs) in the left-side navigation pane.
- On the Virtual Border Routers (VBRs) page, find the VBR that you want to delete and click Delete in the Actions column.
- In the Delete VBR message, click OK.
