在Linux的安装过程中，不少用家有留意RedHat到底帮你安装了什么软件包吗？有把软件包发掘并发挥其功能吗？希望有识之士在空余的时候分别指出一下它们，有助于大家更好地使用Linux。
例如：zebra-0.91a6-i386 http://www.zebra.org
GNU Zebra is free software (distributed under GNU Generic Public License) that manages TCP/IP based routing protocols. It supports BGP-4 protocol as described in RFC1771 (A Border Gateway Protocol 4) as well as RIPv1, RIPv2 and OSPFv2. Unlike traditional, Gated based, 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 in that it has a process for each protocol. Zebra uses multithread technology under multithread supported UNIX kernels. However it can be run under non-multithread supported UNIX kernels. Thus Zebra provides flexibility and reliability. Each module can be upgraded independently of the others, allowing for quick upgrades as well as protection from the case of a failure in one protocol affecting the entire system.
Zebra is intended to be used as a Route Server and a Route Reflector. Zebra is not a toolkit, it provides full routing power under a new architecture.
