Gateway of last resort is 172.17.200.5 to network 0.0.0.0
172.17.0.0/30 is subnetted, 1 subnets

C 10.7.4.0 is directly connected, FastEthernet0/0 C 10.7.2.0 is directly connected, FastEthernet0/1 S* 0.0.0.0/0 [1/0] via 172.17.200.5
步骤9：Ping 7-A的FastEthernet端口的地址 7-B#ping 10.7.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.7.1.1, timeout is 2 seconds: !!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/14/16 ms 7-B#ping 10.7.3.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.7.3.1, timeout is 2 seconds: !!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 12/13/16 ms 步骤10. 在 Route Ｂ 上删除缺省路由配置，配置静态路由 7-B#conf t
Enter configuration commands, one per line. End with CNTL/Z. 7-B(config)# no ip route 0.0.0.0 0.0.0.0 172.17.200.5 7-B(config)#ip route 10.7.1.0 255.255.255.0 172.17.200.5 7-B(config)#ip route 10.7.3.0 255.255.255.0 172.17.200.5 步骤11. 查看路由表 7-B#show ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2
