How can I migrate virtual interfaces to Direct Connect connections or LAG bundles?

Last updated: 2021-01-26

I want to migrate or associate my existing virtual interfaces with AWS Direct Connect connections or LAG bundles. How can I do this?

Short description

If you have a new Direct Connect connection or link aggregation group (LAG) bundle, you might need to migrate or associate it with your virtual interfaces.

Note: When you migrate or associate an existing virtual interface to a new Direct Connect connection, the configuration parameters associated with the virtual interfaces are the same. You can pre-stage the configuration on the Direct Connect connection, and then update the Border Gateway Protocol (BGP) configuration.

Resolution

Note: 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). The virtual interface must be migrated or associated with a LAG bundle (LAG-B).

  1. Open the Direct Connect console.
  2. In the navigation pane, choose Connections.
  3. Select the Direct Connect connection (dxcon-A).
  4. Navigate to the Virtual Interfaces tab, and then select the virtual interface (dxvif-A).
  5. On the Virtual Interfaces tab, choose Edit.
  6. Under Connection, choose the new LAG bundle (LAG-B).
  7. Select the Acknowledge check box, and then choose Edit virtual interface.

The virtual interface goes down for a brief period. Then, the virtual interface is migrated 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 associated with a LAG bundle (LAG-B) that must be moved to another LAG bundle (LAG-C).

  1. Open the Direct Connect console.
  2. In the navigation pane, choose LAGs.
  3. Select the LAG bundle (LAG-B) that has the virtual interface (dxvif-B) that must be moved.
  4. On the Virtual Interfaces tab, select the virtual interface (dxvif-B).
  5. Choose Edit.
  6. Under Connection, choose the new LAG bundle (LAG-C).
  7. Select the Acknowledge check box, and then choose Edit virtual interface.

The virtual interface goes down for a brief period. Then, the virtual interface (dxvif-B) is migrated 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). There's another Direct Connect connection (DX-D) that is UP and operational.

  1. Open the Direct Connect console.
  2. In the navigation pane, choose Connections.
  3. Select the Direct Connect connection (dxcon-C).
  4. On the Virtual Interfaces tab, select the virtual interface (dxvif-C).
  5. Choose Edit.
  6. Under Connection, choose the Direct Connect connection that you must migrate to (DX-D).
  7. Select the Acknowledge check box, and then choose Edit virtual interface.

The virtual interface goes down for a brief period. Then, the virtual interface (dxvif-C) is migrated to the new Direct Connect connection.
