前言

Quagga是一个开源的基于Zebra实现了RIP, OSPF, BGP的动态路由软件。它提供的CLI命令和Cisco IOS类似 - https://blog.csdn.net/quqi99/article/details/9264373
网络测试需要机器来运行Quagga软路由&＃xff0c;也需要机器来运行网络测试机&＃xff0c;用裸机太麻烦&＃xff0c;用虚机也麻烦&＃xff0c;容器内的网络是隔离的还是用LXD容器吧 　&＃xff0d;　https://blog.csdn.net/quqi99/article/details/52131486

注意&＃xff0c;运行此测试&＃xff0c;根目录至少得有5.5G硬盘空间.

sudo /snap/bin/lxc storage list
$ sudo du -h /var/snap/lxd/common/lxd/storage-pools/default |tail -n1
5.5G /var/snap/lxd/common/lxd/storage-pools/default


本测试实现的OSPF网络拓扑如下图所示&＃xff08;也可以使用processon画图) &＃xff0c;两个路由器R1和R2, 两个测试机C1和C1, 三个OSPF AREA (0, 1, 2), 最终的目的得192.168.1.2可以ping通192.168.2.2

Install LXD

sudo snap install lxd
#all options use default values except storage backend&＃61;dir and ipv6&＃61;none
sudo /snap/bin/lxd init
ip addr show lxdbr0
sudo /snap/bin/lxc profile show default
