Quagga如何配置BGP(转载)

1. Quagga软件的安装与启动

1. 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

2. centos如何安装quagga

       yum update
       yum install quagga -y

3. 加载BPG配置文件

     启动软件，Zebra和BGPd一起工作,zebra负责和内核通信交互信息，bgpd守护进程负责bgp的路由发布选择等业务。当它们中的任何一个停止运行时，您的路由都将不再发布；
     复制示例文件，作为模板cp /usr/share/doc/quagga-*/bgpd.conf.sample /etc/quagga/bgpd.conf. 启动bgpd守护进程的前置条件是需要存在/etc/quagga/bgpd.conf，同时需要满足执行权限644等基本需求；启动的实例脚本如下：

   #!/usr/bin/sh
   echo """router bgp 600
   bgp router-id 10.42.104.68
   network 10.10.1.10/32
   neighbor 10.42.104.124 remote-as 300
   neighbor 10.42.104.125 remote-as 300
   ! neighbor 10.0.0.2 route-map set-nexthop out
   ! neighbor 10.0.0.2 ebgp-multihop
   ! neighbor 10.0.0.2 next-hop-self
   !route-map set-nexthop permit 10
   !  match ip address all
   !  set ip next-hop 10.0.0.1
   !
   log file bgpd.log
   """ > /etc/quagga/bgpd.conf
   
   chmod 644 /etc/quagga/bgpd.conf
   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; 执行configure terminal进入配置模式，简写'conf t'；

2. BGP配置示例

router bgp 4242420524
 bgp router-id 172.20.58.193
 neighbor 172.20.158.143 remote-as 4242421331
 neighbor 172.20.158.143 interface LA_NIA
 neighbor 172.20.158.143 description dn42-LA-NIA-AS4242421331-2020-3-21

 neighbor 172.21.100.193 remote-as 4242423088
 neighbor 172.21.100.193 interface LA_SUNNET
 neighbor 172.21.100.193 description dn42-LA-SUNNET-AS4242423088-2020-3-21

 neighbor fe80::2333 remote-as 4242422541
 neighbor fe80::2333 description dn42-TOK-OXYGEN-AS4242422541-2020-3-21

3. 常见操作

官方文档：https://www.quagga.net/docs/quagga.html#Filtering
DN42网络的前缀过滤方式：https://dn42.dev/howto/Quagga

• 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  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
