The following output shows Dell-1 is configured with VLT domain 1. The peer-link port-channel command makes port channel 10
as the VLTi link. The peer-routing command enables peer routing between VLT peers in VLT domain 1. The IP address configured with the
backup-destination command is the management IP address of the VLT peer (Dell-2).
