环境：三台redhat6.5（VM虚拟机）
一、ospf协议
OSPF(Open Shortest Path First开放式最短路径优先）是一个内部网关协议(Interior Gateway Protocol，简称IGP），用于在单一自治系统（autonomous system,AS）内决策路由。是对链路状态路由协议的一种实现，隶属内部网关协议（IGP），故运作于自治系统内部。
PS：这里不过多讲解ospf协议，可在网上自行查找学习
二、配置
首先下载安装软件包，其他yum源以及网络配置就不再介绍了，三台配置也是一样的
下载地址：http://download.openpkg.org/components/cache/quagga/
本人这里使用的版本是quagga-0.99.17.tar.gz
相关依赖包：gcc readline readline-devel
#tar zxf quagga-0.99.17.tar.gz
#yum install -y gcc readline readline-devel
#cd quagga-0.99.17 #进入目录进行源码编译安装
#./configure --enable-vtysh--enable-user=root --enable-group=root --enable-vty-group=root
# make && make install
修改配置文件:
在/etc/services文件里面添加以下内容：
# vim /etc/services
zebrasrv 2600/tcp # zebra service
zebra 2601/tcp # zebra vty
ripd 2602/tcp # RIPd vty
ripngd 2603/tcp # RIPngd vty
ospfd 2604/tcp # OSPFd vty
bgpd 2605/tcp # BGPd vty
ospf6d 2606/tcp # OSPF6d vty
ospfapi 2607/tcp # ospfapi
isid 2608/tcp # ISISd vty
修改quagga的配置文件：
![wKiom1fJTQ6iSTltAAAVsnBY8qs722.png]( "1.png")
# mkdir /usr/local/etc/sample
# mv /usr/local/etc/*.sample/usr/local/etc/sample/
# mv /usr/local/etc/bgpd.conf.sample2/usr/local/etc/sample/
# cp /usr/local/etc/sample/bgpd.conf.sample/usr/local/etc/bgpd.conf
# cp/usr/local/etc/sample/ospfd.conf.sample /usr/local/etc/ospfd.conf
# cp/usr/local/etc/sample/ospf6d.conf.sample /usr/local/etc/ospf6d.conf
# cp /usr/local/etc/sample/ripd.conf.sample/usr/local/etc/ripd.conf
# cp /usr/local/etc/sample/vtysh.conf.sample/usr/local/etc/vtysh.conf
# cp/usr/local/etc/sample/ripngd.conf.sample /usr/local/etc/ripngd.conf
# cp/usr/local/etc/sample/zebra.conf.sample /usr/local/etc/zebra.conf
修改ospfd的配置文件：
# vim /usr/local/etc/ospfd.conf
! -*- ospf -*-
!
! OSPFd sample configuration file
!
!
hostname ospfd
password zebra
enable password please-set-at-here
router ospf
network 10.235.117.0/24 area 0 #将网段宣告进ospf中
log stdout
三、启动验证
接下来启动即可：
# /usr/local/sbin/ospfd -d
# /usr/local/sbin/zebra -d
# vtysh
Hello, this is Quagga (version 0.99.17).

vtysh是quagga进入模拟路由的，进去可以像正常路由器上面命令一样去查看信息。
我这里是启动了三台ospfd进程，配置都是一样的，重复上面步骤即可，赶紧get起来吧！！！
