Quagga如何配置BGP

Quagga软件的安装与启动

安装软件
#A、lede如何安装quagga
    opkg update
    opkg install quagga
    opkg install quagga-zebra quagga-ripd quagga-watchquagga quagga-vtysh quagga-bgpd quagga-ospfd
    /etc/init.d/quagga start    #这是启动
    /etc/init.d/quagga enable   #自启动

#B、centos如何安装quagga
    yum update
    yum install quagga -y

复制示例文件，作为模板
    cp /usr/share/doc/quagga-*/bgpd.conf.sample /etc/quagga/bgpd.conf

启动软件，Zebra和BGPd一起工作。当它们中的任何一个停止运行时，您的路由都将不再发布
    systemctl start zebra
    systemctl enable zebra
    systemctl start bgpd
    systemctl enable bgpd

shell终端内输入"vtysh" 可以进入quagga vty，进行配置调整，语法类似思科CISCO

如下是BGP配置示例

查看BGP汇总：
    show bgp ipv6 unicast summary
    show  ipv6  bgp  summary
    show  ip  bgp  summary

查看向BGP peer通告的路由：
    show bgp ipv6 neighbors <neighbor-IPv6-address> advertised-routes
    show  ip bgp  neighbors  172.20.158.65 advertised-routes

显示从邻居学到的路由
    show  ip bgp  neighbors  172.20.158.65 routes
    show  ipv6 bgp  neighbors  fe80::1331:143:6 routes
