Zebra is a multi-server routing protocol that provides TCP/IP based routing protocols. It's meant to be used as a route server and router reflector. Not just a toolkit, it provides full routing power under a new architecture. The user can dynamically change configuration and use command line completion and history from the terminal interface.

It supports BGP-4 protocol as described in RFC1771 (A Border Gateway Protocol 4) as well as RIPv1, RIPv2 and OSPFv2. Unlike traditional, monolithic architectures and even the so-called "new modular architectures" that remove the burden of processing routing functions from the cpu and utilize special ASIC chips instead, Zebra software offers true modularity.

Zebra is unique in its design because it has a process for each protocol.

Here are some key features of "Zebra":
Due to the multiprocess nature of the Zebra software, it is easily upgraded and maintained. Each protocol can be upgraded separately, leaving the other protocols and the router online. This will save network administrators time in upgrading and maintenance.

Packet routing is carried out at a faster rate than with traditional software. Zebra software allows routers to transfer more data quicker. The need for the ability to transfer large amounts of data quickly is increasing as the internet grows and global networks form. Zebra software will meet that need.

In the event of failure of any of the software modules, the router can remain online and the other protocol daemons will continue to operate. The failure can then be diagnosed and corrected without taking the router offline.
