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

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

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

   #!/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'；

• 查看BGP汇总

  show bgp ipv6 unicast summary show ipv6 bgp summary show ip bgp summary

  1 2 3

  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

  1 2	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

  1 2	show  ip bgp  neighbors  172.20.158.65 routes     show  ipv6 bgp  neighbors  fe80::1331:143:6 routes
