变化太快,时间过的也太快,东西忘记的也太快.......
回忆已经是过去,未来又太遥远,迷茫占据了太多的心思.
公司对我很不错,年终总结有要写对公司来年可以给自己提供什么发展空间.可想了很久感觉自己其实还不可以要求公司什么,因为总感觉自己做的还不够好,不够资格提什么要求,书到用时方恨少,总有种自己知道的东西还很少,然而自己又真的不知道这个缺陷是在哪里,一直在想自己该从哪方面再不断的提高自己,给自己加电,可..

从昨天开始感冒,今天达到高峰,你说计算机病毒残酷吧,可是这感冒病毒似乎更可怕,好好难受啊!想起以前感冒发烧都有人问!现在呢?米人看,米人问,一切都自己承担吧,一个人的精彩,但是那又是建立在什么样的基础之上呢?我不知道,总之感觉自己真的该找个伴了,出门在外的日子实在是不好受啊.上者劳人,这句话真的很不错.
昨天技术部经理出差了,明天回来,刚好改卷子,也刚好到周末,怎么这么巧合,是啊要是结果不好到可以一个电话就解决问题也免了很多的尴尬.今天..

今天 下午进行了公司培训结束后的3结业考试,考的不好, 估计到70的标准有点难度,也就是在那里徘徊吧,不知道是不是其他人不怎么重视的缘故,只要周围环境不好的话,我就没办法正常的做题,也许这是我的很不好的特点吧,要是做事情的话喜欢安静的环境,看到其他人抄,听到其他人说话讨论我自己的思想是一种说不清楚的状态,也 不知道考不过的话还能不能继续呆在这里,会不会明天就是最后来公司的一天呢??我自己也不知道,今天晚上他们改完试卷答案也就出来了,好怕怕如果到不到那个成绩,要真的让走..

培训马上就一周了,明天就要考试一部分了,这些天一直没时间来论坛感觉少了点什么,每天早上7点起床,坐两躺车来到公司,晚上回去也一样,而且每天还要写培训日志,有时候还要做作业,有点象学生时代,不过东西确实挺多的,今天感觉好累,刚把要做的事情给做完,发现公司的员工都不错,下午5点半下班,现在都7点了公司还有7\8 个人米走,并且绝对都不是在上网玩,那边开发部的应该还在写没完的程序吧,旁边的同事还在打电话回访,为客户解决问题,我现在是感觉脑子好混,估计晚上会睡的很香,呵呵.

好好的怀念在西安的日子,这种复杂的心情再次的袭上心头,是因为在上海的无助,还是因为在西安的纯真,我自己也说不清楚.
看到好友们那些怀旧的文章,看着我们大家的照片,心中好酸好酸,昨天自己一个人独自坐在公园的长椅上想了很多,很多.23年的风雨年华,一路走来虽然没有什么大起大落,但我对每个我认识的人都是真心相待,不曾渴求什么,只求认识一起走过就是缘分,从高中三年开始,自己一天天长大,有了一时的冲动,读了自考,也认识了这三四年来要好的朋友,那一幕幕,..

这段时间也不知道自己在忙些什么，一个礼拜了，今天再写点，再不看6月份还怎么考啊/，该实验主要内容：
1）注意有类与无类网络的发布；
2）各种路由协议之间的重发布。
3)R1与R2的S0/0之间为EIGRP,R2的S0/1与R3的S0/0之间为OSPF,R3的回环口为IGRP.
具体过程：
