EIGRP路由泄漏

如图：R1-R4运行EIGRP，R1上有172.16.0.1/24、172.16.1.1/24，172.16.2.1/24和172.16.3.1/24；R1发布4条路由。

默认关闭自动汇总，R2-R3-R4上都可以学习到这4条路由，且R3是从F0/0学到。

要求：R4学习到172.16.0.0/24和172.16.1.0/24走R2；学习172.16.2.0/24和172.16.3.0/24走R3

配置：

R1#routereig 100

no auto

network 10.1.12.0 0.0.0.255

network172.16.0.1 0.0.0.255

network172.16.1.1 0.0.0.255

network172.16.2.1 0.0.0.255

network172.16.3.1 0.0.0.255

第一步：配置列表匹配路由

access-list101 permit ip 172.16.0.0 0.0.1.255 any-----匹配172.16.0.0/24和172.16.1.0/24

access-list110 permit ip 172.16.2.0 0.0.1.255 any-----匹配172.16.2.0/24和172.16.3.0/24

第二步：配置route-map

route-map A permit 10

match ip address 101

route-map Bpermit 10

match ip address 110

第三步：手工汇总、配置LEAK-MAP

interface Serial1/1

ip summary-address eigrp 100 172.16.0.0255.255.252.0 5 leak-map A

interfaceFastEthernet0/0

ip summary-address eigrp 100 172.16.0.0255.255.252.0 5 leak-map B

查看结果：R4上show eigrp路由

R4#sh ip route eigrp

1.0.0.0/32 is subnetted, 1 subnets
