Zebra is publicly available free routing software that is distributed under GNU General Public License. It supports the following IP routing protocols: BGP-4, RIPv1, RIPv2 and OSPFv2. Zebra is unique in its design because it has a process for each protocol that runs on a multithreaded UNIX kernel. Zebra software offers true modularity since each protocol module can be upgraded or configured independently of the others. Zebra support exists for Linux, FreeBSD, NetBSD, OpenBSD and SUN Solaris. This document covers the results of a study conducted for interoperability and functional testing of Zebra protocol modules with Cisco routers. Both systems are compared for their usability, functionality, and supported features. KEY WORDS: Internet Routing Protocols, Internet Architectures, Performance Evaluation, and Interoperability.
