Nevion Modular Routing Protocol (MRP) for router control is supported in Helm, RouteMaster and RouteMaster-NDI. It’s sometimes referred to as the VikingX or Sublime protocol.
RouteMaster uses the protocol for both outgoing and incoming connections, allowing third-party systems using MRP to control RouteMaster. Helm uses it for outgoing connections to control Nevion routers. Because the protocol is used natively by Nevion hardware control panels, you can use Nevion panels to control RouteMaster.
