请求帮助！DCE与DTE之间无法进行正常通讯

whelk

把协议封装成PPP试一下！

znsuper

试过了，不行

hanho

把show interface 情况拿来看看

感觉象是线的问题了，配置没问题啊？

rootstock

两边封装PPP，如果通的话，再转回来

hanho

所以要show interface的情况

DTE
一会 line protocol is down     
一会 line protocol is up

不会吧，我换了两个router还是这样的，你说出现这种现象是正常的么？

znsuper

to rootstock,

如果这样做，两边router全部 Serial0/1 is up, line protocol is down
