采用EIGRP中路由重定向和过滤路由
这是一个在通信机房里完成的采用EIGRP协议里的路由重定向和过滤路由的实验,使用的cisico路由器来完成。下面列出这次实验的拓扑图、实验要求和全部配置,并且附带上一些说明,帮助大家理解。
【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
- http://www.xiaoxiongboke.com
- 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
