-------------------------------------------------
断掉FastEthernet0/1接口(第一条LT路由对应接口),能自动切换至第二条路由
但是恢复FastEthernet0/1接口,等待很长时间,也没有恢复第一路由,
在这种情况下,再点掉Serial0/0/1:0接口时候,整改路由器都连不上了,

Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

Gateway of last resort is 178.2.252.5 to network 0.0.0.0
C 192.168.182.0/24 is directly connected, FastEthernet0/0
178.2.0.0/16 is variably subnetted, 3 subnets, 2 masks
C 178.2.253.104/30 is directly connected, FastEthernet0/1
C 178.2.252.4/30 is directly connected, Serial0/0/1:0
C 178.2.252.5/32 is directly connected, Serial0/0/1:0
S* 0.0.0.0/0 [20/0] via 178.2.252.5 查看路由表,发现一直是这个第二路由
