拓扑图:

无配置分发列表前:
R2:
router ospf 1
redistribute rip metric 100 metric-type 1 subnets
network 192.168.12.0 0.0.0.255 area 0
router rip
version 2
redistribute ospf 1 metric 3
network 200.168.23.0
no auto-summary
R3
:
r3#sh ip rou
R 192.168.12.0/24 [120/3] via 200.168.23.1, 00:00:08, Ethernet0/1
C 200.168.23.0/24 is directly connected, Ethernet0/1
192.168.110.0/32 is subnetted, 1 subnets
R 192.168.110.1 [120/3] via 200.168.23.1, 00:00:08, Ethernet0/1
C 192.168.200.0/24 is directly connected, Loopback0
192.168.100.0/32 is subnetted, 1 subnets
R 192.168.100.1 [120/3] via 200.168.23.1, 00:00:08, Ethernet0/1
r3#
可以看出
R3
学习到了所有的
OSPF
网络中的路由,现在配置路由过渡,只允许
192.168.100.0/24
这条路由被
R3
学习到,其它的不允许!
R2
:加上:
router rip
distribute-list 10 out ospf 1
access-list 10 permit 192.168.100.0 0.0.0.255
R3:
可能要等时间久一点才会有反应:
r3#sh ip rou
C 200.168.23.0/24 is directly connected, Ethernet0/1
C 192.168.200.0/24 is directly connected, Loopback0
192.168.100.0/32 is subnetted, 1 subnets
R 192.168.100.1 [120/3] via 200.168.23.1, 00:00:01, Ethernet0/1
r3#
可以看出只有
192.168.100.0/24
这条路由被
R3
学习到,配置成功!!!
