The Versa Networks SD-WAN solution solely relies on MP-BGP for route distribution. This is achieved via the controllers acting as route reflectors through the secure overlay control channel that each CPE maintains on a per tenant basis with SD-WAN Controllers. Versa Networks SD-WAN solution does not need IGP protocols for MP-BGP next-hop resolution since each CPE are back-to-back/directly connected to each other using secure overlay forwarding tunnels.
The main features of the Versa Networks SD-WAN routing solution are listed below:
- Multiple MPBGP instances each configured within a routing-instance or global hierarchy
- Each MPBGP instance corresponds to a tenant and can support multiple VRFs per tenant
- SD-WAN Controller (Route reflector) reflects the routes to other branches and send to other controllers as well (Route Reflector meshing).
- The route reflector can be different than Controllers where required
Various topologies can be supported on a per VRF basis. These include:
- Hub & Spoke
- Partial-mesh
- Full-mesh
