【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
