A VeloCloud Edge in a data center can act as a hub to direct traffic to/from branches. The VeloCloud Edge can be used to manage both MPLS and Internet traffic. The hub in a data center can be configured in a one-arm or two-arm configuration. In addition, a data center can be used as a backup.
The following describes the various designs with different options of how VeloCloud Edge can be inserted into the topology.
|Hub 1||Data Center or regional hub site with VeloCloud Edge deployed in two-arm topology.|
|Hub 2||Data Center or regional hub site with VeloCloud Edge deployed in one-arm topology (same interface carries multiple WAN links).|
|Legacy 1 and 2||Classic MPLS sites.|
|Silver 1||VeloCloud Edge is deployed off-path. VeloCloud Edge creates overlay across both MPLS and Internet paths. Traffic is first diverted to the VeloCloud Edge.|
|Silver 2||VeloCloud Edge is deployed in-path as the default gateway. It is always the default gateway. This topology is simpler but makes VeloCloud Edge a single point of failure and may require HA.|
|Bronze 1||Dual-Internet site (one of the links is behind a NAT router).|
