PPPOE 配置不通

Fission

两台设备直连配置PPPOE 获取到了地址 但是ping不通。接口下直接配置地址就可以通。用的是WEB-iou
R26是服务器端
Cisco IOS Software, Linux Software (I86BI_LINUX-TPGEN+ADVENTERPRISEK9-M), Experimental Version 12.4
R27是客户端
Cisco IOS Software, Linux Software (I86BI_LINUX-ADVENTERPRISEK9-M), Version 15.2(2.15)T, ENGINEERING WEEKLY BUILD, synced to V151_4_M3_5

下面开始上配置

PPPOE获取到了地址但是就是不通

leless_1987

使 tsv5 ex 吗？

sanming110

能不能挣点分啊 谢谢了

Fission

谢谢各位了 问题找到了  就是 ios 版本的问题  我换成一样就好了

maxqueen

配置没问题，能ping通。我GNS3试过了

Rockyw

路过了解一下

ziyouhaiyang

carzzz

ip unnumbered Ethernet0/0

这条命令，删掉试试？

mywolfking

自己在R27上开debug ip rip 看看，就会发现R27把R26的路由忽略掉了。。在R27的RIP里敲no   validate-update-source忽略来源检查就可以看到默认路由了。

kgdpgf

客户端没路由？ip route add 0.0.0.0 0.0.0.0 dialer1  试试
