此時(shí)R3學(xué)到4外部路由,我們希望作如下修改。
222.222.222.0/24????修改為E1
2.2.2.0/24????????? 修改default Seed Metrics為10
22.22.22.0/24????? ?deny掉,permit any
R1配置
ip prefix-list 222 seq 5 permit 222.222.222.0/24
access-list 2 permit 2.2.2.0 0.0.0.255
access-list 22 permit 22.22.22.0 0.0.0.255
route-map RM permit 10
?match ip address prefix-list 222
?set metric-type type-1
route-map RM permit 20
?match ip address 2
?set metric 10
route-map RM deny 30
?match ip address 22
route-map RM permit 40
router ospf 110
?redistribute rip subnets route-map RM
可以看到結(jié)果與我們的需求一致。
