如何进行route-map解析

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。
