初识quagga

http://en.wikipedia.org/wiki/Quagga_%28software%29

The Quagga architecture consists of a core daemon (zebra) which is an abstraction layer to the underlying Unix kernel and presents the Zserv API over a Unix-domain socket or TCP socket to Quagga clients. The Zserv clients typically implement a routing protocol and communicate routing updates to the zebra daemon. Existing Zserv clients are:

    ospfd, implementing Open Shortest Path First (OSPFv2)
    ripd, implementing Routing Information Protocol (RIP) version 1 and 2;
    ospf6d, implementing Open Shortest Path First (OSPFv3) for IPv6
    ripngd, implementing Routing Information Protocol (RIPng) for IPv6
    bgpd, implementing Border Gateway Protocol (BGPv4+), including address family support for IP multicast and IPv6
    babeld, implementing the Babel routing protocol, including support for both IPv4 and IPv6 and for both wired networks and wireless mesh networks.

Additionally, the Quagga architecture has a rich development library to facilitate the implementation of protocol and client software with consistent configuration and administrative behavior.



Linux 路由软件 Quagga包含一个核心守护进程zebra，它作为Unix底层核心的一个抽象层，表示为Unix上的一些Zserv API或Linux Quagga客户端的TCP流。这些Linux Quagga客户端实现路由协议并和zebra守护程序交换路由更新信息。

这些Zserv客户端包括：

ospfd：实现OSPFv2

ripd：实现RIPv1和RIPv2

ospf6d：实现OSPFv3（IPv6）

ripngd：实现RIPv3（IPv6）

bgpd：实现BGP4+（包括对组播地址族和IPv6地址族的支持）
