To show the IP routing table, use the
show ip route
sho ip routeCodes: C - connected, S - static, I - IGRP, 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, E - EGP i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route Gateway of last resort is 220.127.116.11 to network 0.0.0.0 172.16.0.0/16 is variably subnetted, 6 subnets, 2 masks D 172.16.200.0/23 is a summary, 00:56:18, Null0 C 172.16.200.0/24 is directly connected, Loopback2 C 172.16.201.0/24 is directly connected, Serial0/0 C 172.16.202.0/24 is directly connected, Loopback3 C 172.16.100.0/23 is directly connected, Loopback4 D 172.16.101.0/24 [90/2172416] via 18.104.22.168, 00:53:07, FastEthernet0/1 C 10.0.0.0/8 is directly connected, FastEthernet0/0 C 22.214.171.124/8 is directly connected, FastEthernet0/1 192.168.1.0/32 is subnetted, 1 subnets D 192.168.1.11 [90/156160] via 126.96.36.199, 00:00:03, FastEthernet0/1 S* 0.0.0.0/0 [1/0] via 188.8.131.52 D 10.0.0.0/7 is a summary, 00:54:40, Null0
The first block of information is shown every time the command is executed. In the interest of brevity, I will remove it from most of the examples in this book. This block is a key that explains the codes listed down the left side of the routing ...
