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.

Option Description
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).
