在另一台路由器Branch上进行相同配置，即可实现互相访问，注意掩码
相关设置：
HQ: e0/1 192.168.1.2 255.255.255.252
e0/0 172.16.1.100 255.255.255.248
Branch： e0/1 192.168.1.1 255.255.255.0
e0/0 10.1.10.23 255.255.255.240
重要命令：show ip route 显示路由表
ip route + ip地址 +掩码 手工设置静态路由表
注：当使用 ip route + ip地址 +掩码 命令手工设置静态路由表时，此处ip地址应写箭头处地址，而非local ip地址。
