36、重分布配置实验之route-map

1、route-map解析

2、实验拓扑

3、实验配置

R1配置

interface Serial0/0

 ip address 12.1.1.1 255.255.255.0

interface Serial0/1

 ip address 13.1.1.1 255.255.255.0

interface Serial0/2

 ip address 14.1.1.1 255.255.255.0

router eigrp 90

 redistribute ospf 110 metric 1500 100 255 1 1500

 network 14.1.1.0 0.0.0.255

 no auto-summary

router ospf 110

 router-id 1.1.1.1

 log-adjacency-changes

 redistribute rip subnets

 network 13.1.1.0 0.0.0.255 area 0

router rip

 version 2

 network 12.0.0.0

 no auto-summary

R2配置

interface Loopback0

 ip address 2.2.2.2 255.255.255.0

interface Loopback22

 ip address 22.22.22.22 255.255.255.0

interface Loopback222

 ip address 222.222.222.222 255.255.255.0

interface Serial0/0

 ip address 12.1.1.2 255.255.255.0

router rip

 version 2

 network 2.0.0.0

 network 22.0.0.0

 network 222.222.222.0

 network 12.0.0.0

 no auto-summary

R3配置

interface Loopback0

 ip address 3.3.3.3 255.255.255.0

interface Serial0/0

 ip address 13.1.1.3 255.255.255.0

router ospf 110

 router-id 3.3.3.3

 log-adjacency-changes

 network 3.3.3.0 0.0.0.255 area 0

 network 13.1.1.0 0.0.0.255 area 0

R4配置

interface Loopback0

 ip address 4.4.4.4 255.255.255.0

interface Serial0/0

 ip address 14.1.1.4 255.255.255.0

router eigrp 90

 network 4.4.4.0 0.0.0.255

 network 14.1.1.0 0.0.0.255

 no auto-summary

此时R3学到4外部路由，我们希望作如下修改。

222.222.222.0/24    修改为E1

2.2.2.0/24          修改Default Seed Metrics为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

可以看到结果与我们的需求一致。
