我前天在学校,遇到一个非常蹊跷又头痛的问题。我在gns3中只拉了一个c3600路由和一台pc连起来,新建vlan 2并设置ip作为网关,把pc所在接口加入到vlan 2后,设置好网关但死活ping不到这个网关,这么简单的俩玩意儿怎么会出这个问题?检查半天配置,一共就没几条可写的指令咋会不成呢?研究半天未果,回家继续研究。经过数十次的实验,有时能成功有时不行,最后用show ip int f1/3查到f1/3接口处是f1/3 is up,line protocol is down.先想到了是不是这个pc端有啥问题,把pc的线断了再连上,还是down.没辙上百度查查,人家说,这不是连接线有问题,就是机器有故障(真实设备)。可我这是gns3模拟啊,有啥问题呢?百思不得其解啊。又经过n次的实验,终于发现了问题关键。
问题确实是gns3不人性化造成的,必须先把所有线连好,设备的各种模块都插到槽中就位了,再start路由、交换机设备方可!
那些各种down的问题,都是因为这破模拟器不能实时检查变更造成的!只要特权模式下wr一下然后reload亦可解决这问题。。。不过显然麻烦一些不是么。
