工业级无线路由器OSPF协议常见故障

文章目录 : 产品文章

邻居及邻接关系出现问题大致情况如下

1. OSPF没有在接口上启用,或者一条网络工业路由器配置命令错误或丢失

2. 不匹配的Hello或者计时器,E位,区域ID,认证类型或者网络掩码

3. 访问列表错误配置,可能正在阻塞全网通工业级路由器OSPF hello包

4. 虚拟链路和末节设置不匹配

5. 接口被定义为passive-mode

6. 不匹配的认证类型

7. 不匹配的认证密钥

8. 第2层停机

9. 没有在全网通工业路由器NBMA上定义网络类型

10. FR或dialer缺少broadcast关键字

工业级全网通路由器OSPF停滞在INIT状态【4g路由器

检查方法如下:

1. 一端正在阻塞hello分组

2. 一端NAT转换了工业全网通路由器OSPF hello 包

3. 一端的组播能力被破坏

4. 肯定是一个2层的问题

5. Dialer或FR缺少broadcast

6. 工业级路由器发送hello,但没有收到响应

7. 邻居hello在NBMA云团中消失

8. 工业无线路由器ACL或者某些2层原因拒绝了hello包

OSPF停滞在Exstart/Switching状态

检查方法如下:【全网通4g路由器

1. MTU不匹配

2. 邻居工业4G路由器RID是一致的

3. 单播被破坏

在一个高度冗余的网络中,Frame/ATM环境中错误的VC/DLCI映射

MTU的问题,不能使用超过某长度的分组

ACL阻塞单播

NAT正在转换单播分组

4. 在工业级4G路由器PRI和BRI/dialer和网络类型之间是点到点的
