C2600路由器在引导的时候为什么要进行两次解压呢?

没有错，我把NVRAM察除了一次，重新初始化配置后就OK了。
这个问题真奇怪哦！

这个是什么意思啊？我把NVRAM格了一下，重新初始化路由配置后，重启就只自解压一次了。

哦。那就无从查起了。不过我也是第一次看到。

找到原因了,原来是升级IOS后,执行了boot system flash:   它在start run文件中 生成了一个引导语句,  也就是说,路由器从flash中装安IOS后,读取start run文件,执行了其中的boot语句,又从flash中装载了一次IOS.     


   boot system flash 这个在中高端路由器上升级IOS后需要执行的命令,在低端路由器上无需执行.

哦。原来如此啊。受教了。
