路由器1不知道路由

Question

你好,

我已经用版本2激活了所有3个路由器上的rip，但是R1没有打开R3，反之亦然。我已经用他们的ips配置了交换机的vlans。我已经试了一段时间来解决这个问题。

**Router 1 : show ip protocols**
Routing Protocol is "rip"
  Outgoing update filter list for all interfaces is not set
  Incoming update filter list for all interfaces is not set
  Sending updates every 30 seconds, next due in 19 seconds
  Invalid after 180 seconds, hold down 180, flushed after 240
  Redistributing: rip
  Default version control: send version 2, receive version 2
    Interface             Send  Recv  Triggered RIP  Key-chain

我不知道问题出在哪里。请帮帮忙

Answer 1

接口F0/0和F0/1在R1上配置错误。

R1接口F0/0配置为192.168.137.0/24而不是10.24.0.0/24。R1接口F0/1配置为10.24.0.0/24而不是192.168.137.0/24。我建议要么“交换”您的电缆，要么重新IP寻址您的接口。
