归属地路由器HomeRouter
RouterHome#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
RouterHome(config)#interface FastEthernet0/0
RouterHome(config-if)#ip address 192.168.10.1 255.255.255.0
RouterHome(config-if)#ip proxy-arp
RouterHome(config-if)#ip mobile arp
RouterHome(config-if)#exit
RouterHome(config)#router eigrp 99
RouterHome(config-router)#network 192.168.10.0
RouterHome(config-router)#default-metric 10000 10 255 1 1500
RouterHome(config-router)#redistribute mobile
RouterHome(config-router)#no auto-summary
RouterHome(config-router)#exit

访问地路由器ForeignRouter
RouterForeign#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
RouterForeign(config)#interface FastEthernet0/0
RouterForeign(config-if)#ip address 192.168.110.1 255.255.255.0
RouterForeign(config-if)#ip proxy-arp
RouterForeign(config-if)#ip mobile arp
RouterForeign(config-if)#exit
RouterForeign(config)#router eigrp 99
RouterForeign(config-router)#network 192.168.100.0
RouterForeign(config-router)#default-metric 10000 10 255 1 1500
RouterForeign(config-router)#redistribute mobile
RouterForeign(config-router)#no auto-summary
RouterForeign(config-router)#exit
RouterForeign(config)#end

注释 Local Area Mobility是思科通过Proxy Arp来实现的一种简单移动IP，只是作为没有DHCP的暂时替代方案，当访问地使用ARP查到了访问设备以后会在路由表生成一条主机路由，然后此主机路由会通过路由协议被归属地所学到，比如访问地的ARP和路由表
RouterForeign#show ip arp FastEthernet0/0
