Virtual border router

Last Updated: Dec 15, 2017

What is a virtual border router

A virtual border router (VBR) is a product mapping of the leased line that you have applied to access a VSwitch. You can think of it as a router between your customer-premises equipment (CPE) and the VPC, which serves as a bridge for exchanging data between the on-premises IDC and the VPC.
