The Zebra applies a strict layered architecture. It is divided into three main layers, the Routing Protocols layer, which comprises of all the routing protocols supported by Zebra, the Zebra manager layer and the OS kernel layer. The routing protocol layer communicates only with the zebra manager and supplies the routing information to it. The zebra manager is responsible for building and updating the kernel routing table. The Routing protocol layer has no knowledge or interaction with the OS kernel layer. If we want to add new routing protocol we only need to know about the communication interface between the Routing protocol layer and the Zebra manager layer.
