大家好,问题很奇怪。R2有172.16.8.0/24--172.16.11.0/24四条连续的路由条目,在R2的F0/1口上做rip 的手动汇总。之后在R1的路由表上没有这条汇总路由的路由条目。网络不同。没汇总成172.16.8.0/22的时候,路由R1有四条关于172.16.0.0/24的明细路由,网络正常。手动汇总后重新清除下路由表,明细路由条目消失,R1也无法获悉汇总条目。大家麻烦指点指点,谢谢!
R1路由表信息:
R1#sh ip route
Gateway of last resort is not set
1.0.0.0/24 is subnetted, 1 subnets
C 1.1.1.0 is directly connected, Loopback1
3.0.0.0/24 is subnetted, 1 subnets
R 3.3.3.0 [120/1] via 23.1.1.1, 00:00:06, FastEthernet0/1
23.0.0.0/24 is subnetted, 1 subnets
C 23.1.1.0 is directly connected, FastEthernet0/1
