Associating a Virtual Interface with a Connection or LAG

You can associate a virtual interface with a link aggregation group (LAG), or another connection.

You cannot associate a virtual interface if the target connection or LAG has an existing associated virtual interface with the following matching attributes:

  • A conflicting VLAN number

  • (Public virtual interfaces) The same IP address range for the Amazon router, or for the customer router

  • (Private virtual interfaces) The same virtual private gateway and the same IP address range for the Amazon router, or for the customer router

You cannot disassociate a virtual interface from a connection or LAG, but you can re-associate it or delete it. For more information, see Deleting a Virtual Interface.

Important

Connectivity to AWS is temporarily interrupted during the association process.
