+本实验配套的 Makefile 位于本文件的同目录，其使用方法如下：
+
+
+**创建网络环境1**
+
+```sh
+# make create-net1
+```
+
+**创建网络环境2**
+
+```sh
+# make create-net2
+```
+
+**创建 bridge**，并把 net1、net2中的“网线插头”给接上
+
+```sh
+# make create-br 
+```
+
+从 net1 的网络环境中 ping 一下 net2 试试
+
+```sh
+# ip netns exec net1 ping 192.168.0.102 -I veth1
+PING 192.168.0.102 (192.168.0.102) from 192.168.0.101 veth1: 56(84) bytes of data.
+64 bytes from 192.168.0.102: icmp_seq=1 ttl=64 time=0.037 ms
+64 bytes from 192.168.0.102: icmp_seq=2 ttl=64 time=0.008 ms
+64 bytes from 192.168.0.102: icmp_seq=3 ttl=64 time=0.005 ms
+```
+
+最后，清理实验所创建的各种虚拟网络设备
+
+```sh
+# make clean
+```
