H3C MSR路由器E1接口与中兴ZXR10 6800路由器CE1接口做广域网对接案例

这个是一个哥们搞的某局点客户，问题是用H3C MSR路由器E1接口与中兴ZXR10 6800路由器CE1接口做广域网对接不起来，我在这里MARK下，如果以后有需要的兄弟可以参考。

一开始对接不成功对半是因为两端参数不一致，这次是因为两端的接口帧间填充符类型（itf type）不一致造成，H3C 默认的是0x7e的方式，而中兴的是0xff的方式。

下面是中兴6800主要配置
$
controller ce1-3/1
  unframe               #工作在非成帧方式
  itf-type 0x7e         #配置接口的帧间填充符类型

$
interface ce1-4/1:1
  description TO-THJ
  ip address 10.17.3.13 255.255.255.252
  no shutdown

下面是H3C MSR主要配置
#
interface Serial2/0
 fe1 unframed              #工作在非成帧方式
 link-protocol ppp
 ip address 10.17.3.14 255.255.255.252

在这里给出两端设备的接口默认信息，我重各自的手册里面找的，希望对大家有用。

下面是H3C的E1接口默认参数配置
