查看R4的路由表

将掩码都改为24
在这里插入图片描述

OSPF向RIP的重分布

在R2出口处，抓取4.4.4.0和34.1.1.0，然后加大其度量，使R1走最佳路径

R2

[r2]ip ip-
[r2]ip ip-prefix c permit 4.4.4.0 24
[r2]ip ip-prefix c permit 34.1.1.0 24

[r2-GigabitEthernet0/0/0]rip metricout ip-
[r2-GigabitEthernet0/0/0]rip metricout ip-prefix c 3

在R4出口处，抓取23.1.1.0，然后加大其度量，使R3走最佳路径
