时间Tue Mar 22 15:15:35 2011
今天连上去看cisco router
看了上面的设定发现,我怎麽看不太懂= =
172.30.0.0/30 is subnetted, 1 subnets
C 172.30.62.76 is directly connected, Serial0/0/0
173.30.0.0/30 is subnetted, 1 subnets
C 173.30.32.72 is directly connected, FastEthernet0/1
10.0.0.0/24 is subnetted, 1 subnets
S 10.41.0.0 [1/0] via 192.168.1.253
C 192.168.1.0/24 is directly connected, FastEthernet0/0
S* 0.0.0.0/0 [1/0] via 192.168.1.253
S 192.168.0.0/16 is directly connected, Serial0/0/0
请问上面代表是什麽意思?
另外,我们的f0/1是173.30.32.74 s0/0是173.30.62.78!
