I want to migrate or associate my existing virtual interfaces with AWS Direct Connect connections or link aggregation group (LAG) bundles.
Resolution
Prerequisite: Before you perform the resolution, review the following points:
- When you migrate or associate an existing virtual interface to a new Direct Connect connection, the configuration parameters that are associated with the virtual interfaces are the same. You can pre-stage the configuration on the Direct Connect connection, and then update the BGP configuration.
- You can migrate or associate a virtual interface with a Direct Connect connection or LAG only in the same AWS account and AWS Region.
- You can migrate a virtual interface to a new connection or a LAG in the same AWS Region. You can't migrate a virtual interface from one Region to another Region.
- You can't migrate a virtual interface from one hosted connection to another hosted connection. Because VLAN IDs are unique, migrating a virtual interface means the VLANs don't match. You must delete either the connection or the virtual interface. Then, use a VLAN that's the same for both the connection and the virtual interface to recreate what you deleted.
Note: When you move the virtual interface, the virtual interface is down for a brief period. It's a best practice to perform these steps during a scheduled maintenance window to minimize downtime.
Migrate an existing virtual interface associated with a Direct Connect connection to a new LAG bundle
In this example, you have a virtual interface dxvif-A that's associated with a Direct Connect connection dxcon-A. dxvif-A must be migrated or associated with a LAG bundle LAG-B.
- Open the Direct Connect console.
- In the navigation pane, choose Virtual interfaces.
- Select dxvif-A, and then choose Edit.
- For Connection, choose LAG-B.
- Select the agreement check box.
- Choose Edit virtual interface.
The virtual Interface dxvif-A migrates to the new LAG bundle LAG-B.
Migrate an existing virtual interface associated with a LAG bundle to another LAG bundle
In this example, the virtual interface dxvif-B is active and associated with a LAG bundle LAG-B. dxvif-B must be migrated or associated with another LAG bundle LAG-C.
- Open the Direct Connect console.
- In the navigation pane, choose Virtual interfaces.
- Select dxvif-B, and then choose Edit.
- For Connection, choose LAG-C.
- Select the agreement check box.
- Choose Edit virtual interface.
The virtual Interface dxvif-B migrates from the existing LAG bundle LAG-B to the new LAG bundle LAG-C.
Migrate an existing virtual interface associated with a Direct Connect connection to another Direct Connect connection
In this example, the virtual interface dxvif-C is active and associated with a Direct Connect connection DX-C. You have another Direct Connect connection DX-D that's UP and operational. You want to migrate the virtual interface dxvif-C from the existing Direct Connect connection DX-C to the new Direct Connect connection DX-D.
- Open the Direct Connect console.
- In the navigation pane, choose Virtual interfaces.
- Select dxvif-C, and then choose Edit.
- For Connection, choose DX-D.
- Select the agreement check box.
- Choose Edit virtual interface.
The virtual interface dxvif-C migrates from the existing Direct Connect connection DX-C to the new Direct Connect connection DX-D.
Migrate an existing virtual interface associated with a Direct Connect LAG to another Direct Connect connection
In this example, the virtual interface dxvif-D is active and associated with a Direct Connect LAG bundle LAG-D. You have another Direct Connect connection DX-E that's UP and operational. You want to migrate the virtual interface dxvif-D from an existing Direct Connect LAG bundle LAG-D to a new Direct Connect connection DX-E.
To migrate dxvif-D to DX-E, complete the following steps:
- Open the Direct Connect console.
- In the navigation pane, choose Virtual interfaces.
- Select dxvif-D, and then choose Edit.
- For Connection, choose DX-E.
- Select the agreement check box.
- Choose Edit virtual interface.
The virtual interface dxvif-D migrates from the existing Direct Connect LAG bundle LAG-D to the new Direct Connect connection DX-E.
