CCNP路由重分发（三）EIGRP-to-OSPF

这个实验做一下EIGPR网络与OSPF网络之间的路由重分发，实验拓扑如下：

 

 

实验用的时小凡的模拟器，路由器连接拓扑如下表：

Router1 S0/0 <----> Router2 S0/1
Router2 S0/0 <----> Router3 S0/1
Router3 S0/0 <----> Router4 S0/1

为配置路由重分发时各路由器上的路由表状况：
R1#sh ip route

在路由器R2上配置路由重分发：

R2#sh run | be router
router eigrp 100
 redistribute ospf 1 metric 2000 100 255 1 1500
 network 10.0.0.0
 auto-summary
!
router ospf 1
 log-adjacency-changes
 redistribute eigrp 100 metric 200 subnets
 network 10.0.0.8 0.0.0.3 area 0
