The following output shows Dell-2 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-1). A priority value of
55000 makes Dell-2 as the secondary VLT peer.
