EIGRP中路由重定向与过滤路由

【实验拓扑】

 

 

【实验要求】

1、按照上图配置好接口地址与EIGRP

2、在R5上创建 loopback1：150.1.55.55/24，创建loopback2：150.1.155.155/24

3、在R5上使用route-map重定向Loopback1与Loopback2到EIGRP中，并且分配Loopback1的tag值为100

4、在R4上使用route-map只允许tag值为100的路由进来，需要应用在s0/0与s0/1接口上

 

【实验配置】

第一步配置：

R4配置：

interface Loopback0

 ip address 150.1.4.4 255.255.255.0

!

interface FastEthernet0/0

 no ip address

 shutdown

 duplex auto

 speed auto

!

interface Serial0/0

 bandwidth 256

 ip address 155.1.0.4 255.255.255.0

 encapsulation frame-relay

 clock rate 2000000

 frame-relay map ip 155.1.0.5 405 broadcast

 no frame-relay inverse-arp

!

interface Serial0/1

 bandwidth 64

 ip address 155.1.45.4 255.255.255.0

 clock rate 2000000

!

router eigrp 100

 network 150.1.4.4 0.0.0.0

 network 155.1.0.4 0.0.0.0

 network 155.1.45.4 0.0.0.0

 no auto-summary

 

R5配置：

interface Loopback0

 ip address 150.1.5.5 255.255.255.0

!

interface Serial0/0

 bandwidth 256

 ip address 155.1.0.5 255.255.255.0

 encapsulation frame-relay

 clock rate 2000000

 frame-relay map ip 155.1.0.4 504 broadcast

 no frame-relay inverse-arp

!

interface Serial0/1

 bandwidth 64

 ip address 155.1.45.5 255.255.255.0

 clock rate 9600

!

router eigrp 100

 network 150.1.5.5 0.0.0.0

 network 155.1.0.5 0.0.0.0

 network 155.1.45.5 0.0.0.0

 no auto-summary

配置完成之后R4与R5能够互相学习到对方的loopback0地址，

R4#show ip eigrp neighbors

IP-EIGRP neighbors for process 100

H   Address                 Interface       Hold Uptime   SRTT   RTO  Q  Seq

                                            (sec)         (ms)       Cnt Num

1   155.1.0.5               Se0/0            165 00:39:59  196  1176  0  27

0   155.1.45.5              Se0/1             14 00:42:27   67  2280  0  28

 

第二步： 接下来的配置

R5:

interface Loopback1

ip address 150.1.55.55 255.255.255.0

!

interface Loopback2

ip address 150.1.155.155 255.255.255.0

!

router eigrp 100

redistribute connected route-map CONNECTED_TO_EIGRP

route-map CONNECTED_TO_EIGRP permit 10

match interface Loopback1

set tag 100

route-map CONNECTED_TO_EIGRP permit 20

match interface Loopback2

 

R4:

route-map FILTER_EIGRP 10

match tag 100

!

router eigrp 100

distribute-list route-map FILTER_EIGRP in serial 0/1

distribute-list route-map FILTER_EIGRP in serial 0/0

 

【验证配置】

配置过滤之前

R4#show ip route eigrp

150.1.0.0/24 is subnetted, 4 subnets

D EX 150.1.155.0 [170/10639872] via 155.1.0.5, 00:00:05, Serial0/0

D 150.1.5.0 [90/10639872] via 155.1.0.5, 01:18:07, Serial0/0

D EX 150.1.55.0 [170/10639872] via 155.1.0.5, 00:00:56, Serial0/0

配置过滤之后:

R4#show ip route eigrp

150.1.0.0/24 is subnetted, 2 subnets

D EX 150.1.55.0 [170/10639872] via 155.1.0.5, 00:02:59, Serial0/0
