pin sha 抓包 protoc 拓撲 配置 con address add 1、實驗拓撲：
2、命令部署：
R1(config)#ip route 0.0.0.0 0.0.0.0 f0/0 其余配置和Normal-ARP一樣
dst 12.1.1.1 c001.1858.0000 FastEthernet0/0 
2、命令部署：
R1(config)#ip route 0.0.0.0 0.0.0.0 f0/0 其余配置和Normal-ARP一樣
3、驗證：
（1）命令部署：
R2#debug arp
ARP packet debugging is on
R1#ping 3.3.3.3
（2）抓包驗證：
R2#
