You can use BGP to connect a VBR to a local data center. You only need to add BGP peers that communicate with the VBR to the corresponding BGP group, and advertise the BGP network in the VBR, then BGP dynamic routing can be achieved between the local data center and the VBR.

Note BGP can only be used to achieve dynamic routing between a local data center and a VBR. If you need to connect a local data center to a VPC, you still need to configure a static route for the VBR and the VPC respectively. For more information, see Access a VPC under the same account through a physical connection.
