Quagga 是开源的软路由，运行在 Linux 系统上，让 Linux 系统支持 OSPF 等路由协议和 routemap 等路由策略。
1 、安装
Quagga 官网：http://www.nongnu.org/quagga/
CentOS7 中，安装 Quagga 使用 yum 安装即可
yum install quagga
而在 CentOS7 中，由于 SELINUX 的存在，所以需要额外配置一下允许 Quagga 进程对本地磁盘的操作
setsebool -P zebra_write_config 1
安装好后，复制 Quagga 的配置文件模板并将 Quagga 设置为开机启动和运行 Quagga 。（XXXXX 为版本号，输入时请使用 Tab 补全）
cp /usr/share/doc/quagga-XXXXX/zebra.conf.sample /etc/quagga/zebra.conf systemctl enable zebra.service systemctl start zebra.service
2 、调试
Quagga 需要 vtysh 命令进入路由器模式，并且由于首次使用，建议创建一个日志文件。
Router# configure terminal Router(config)# log file /var/log/quagga/quagga.log Router(config)# exit Router# write
Quagga 的命令格式和 Cisco 基本一致，所以可以使用以下命令查看路由器状态
查看当前所有端口信息 Router# show interface 查看当前运行配置 Router# show running-config 查看当前路由表 Router# show ip route 查看当前 Quagga 版本号 Router# show version
3 、命令表
Quagga 的命令不多，所以在这贴几份命令表
第一份是 Router#?
第二份是 Router#show ?
第三份是 Router(config)#?
