實驗拓撲圖:
實驗內容:
路由器的配置
先來看R1上的配置
Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
粘貼上基本命令
Router(config)#enable password cisco
Router(config)#no ip domain-lookup
Router(config)#line con 0
Router(config-line)# exec-timeout 0 0
Router(config-line)# logging synchronous
Router(config-line)#
Router(config-line)#line aux 0
Router(config-line)# exec-timeout 0 0
Router(config-line)# logging synchronous
Router(config-line)#line vty 0 4
Router(config-line)#
Router(config-line)#
Router(config-line)# exec-timeout 0 0
Router(config-line)# password cisco
Router(config-line)#
Router(config-line)# login
Router(config-line)#
Router(config-line)#
Router(config-line)#alias exec a sh ip int bri
Router(config)#alias exec b sh ip route
Router(config)#alias exec c sh ip route rip
Router(config)#alias exec d sh run
Router(config)#
Router(config)#host R1
R1(config)#interface e0/0
R1(config-if)#ip address 172.16.1.1 255.255.255.0
R1(config-if)#no shutdown
接下來配置名稱,各接口地址
R1(config-if)#exit
R1(config)#interface s1/0
R1(config-if)#ip address 10.1.1 .1 255.255.255.0
R1(config-if)#clock rate 64000
R1(config-if)#no shutdown
同理R2上的配置,粘貼命令部分省略
Router(config)#host R2
R2(config)#interface s1/1
R2(config-if)#ip address 10.1.1 .2 255.255.255.0
R2(config-if)#no shutdown
R2(config-if)#exit
R2(config)#interface s1/0
R2(config-if)#ip address 10.2.2 .2 255.255.255.0
R2(config-if)#clock rate 64000
R2(config-if)#no shutdown
R3上的配置
Router(config)#host R3
R3(config)#interface s1/1
R3(config-if)#ip address 10.2.2 .3 255.255.255.0
R3(config-if)#no shutdown
R3(config-if)#exit
R3(config)#interface e0/0
R3(config-if)#ip address 192.168.1.1 255.255.255.0
R3(config-if)#no shutdown
好了,現在開始配置EIGRP
先從R1上開始
R1(config)#router eigrp 100
R1(config-router)#network 172.16.0.0
R1(config-router)#network 10.0.0 .0
R1(config-router)#exit
R2上的配置
R2(config)#router eigrp 100
R2(config-router)#network 10.0.0 .0
R3上的配置
R3(config)#router eigrp 100
R3(config-router)#network 192.168.1.0
R3(config-router)#network 10.0.0 .0
最後讓我們來驗證一下EIGRP的配置是否生效
看下R1的上
R1#show ip eigrp neighbors
IP-EIGRP neighbors for process 100
H Address Interface Hold Uptime SRTT RTO Q Seq
(sec) (ms) Cnt Num
0 10.1.1 .2 Se1/0 12 00:01:11 81 486 0 5
這命令是查看EIGRP的鄰居的
R1#show ip eigrp topology
IP-EIGRP Topology Table for AS(100)/ID(172.16.1.1)
Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply,
r - reply Status, s - sia Status
via 10.1.1 .2 (2681856/2169856), Serial1/0
via Summary (2169856/0), Null0
via Connected, Serial1/0
P 192.168.1.0/24, 1 successors, FD is 2707456
via 10.1.1 .2 (2707456/2195456), Serial1/0
P 172.16.0.0/16, 1 successors, FD is 281600
via Summary (281600/0), Null0
P 172.16.1.0/24, 1 successors, FD is 281600
via Connected, Ethernet0/0
R1#show ip route eigrp
172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks
D 172.16.0.0/16 is a summary, 00:02:21, Null0
D 10.2.2 .0/24 [90/2681856] via 10.1.1 .2, 00:01:43, Serial1/0
D 10.0.0 .0/8 is a summary, 00:02:21, Null0
D 192.168.1.0/24 [90/2707456] via 10.1.1 .2, 00:01:23, Serial1/0
該命令查看EIGRP的拓撲路由表的,上面可以看出R1已經學習到了R2,R3上的EIGRP信息
R1#show ip protocols
Routing Protocol is "eigrp 100"
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
Default networks flagged in outgoing updates
Default networks accepted from incoming updates
EIGRP metric weight K1=1, K2 =0, K3=1, K4=0, K5=0
EIGRP maximum hopcount 100
EIGRP maximum metric variance 1
Redistributing: eigrp 100
EIGRP NSF-aware route hold timer is 240s
Automatic network summarization is in effect
Automatic address summarization:
172.16.0.0/16 for Serial1/0
Summarizing with metric 281600
Summarizing with metric 2169856
Maximum path: 4
Routing for Networks:
172.16.0.0
Routing Information Sources:
Gateway Distance Last Update
(this router) 90 00:02:34
Distance: internal 90 external 170
這命令即詳細地顯示了運行的EIGRP協議的信息,還有運行着的路由狀態信息.

最後這條命令即是查看有關EIGRP協議的數據包發送和接收的數量.
看完R1的,再看一下R2的
R2#show ip eigrp topology
IP-EIGRP Topology Table for AS(100)/ID(10.2.2 .2)
Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply,
r - reply Status, s - sia Status

P 172.16.0.0/16, 1 successors, FD is 2195456
via 10.1.1 .1 (2195456/281600), Serial1/1
R2#show ip route eigrp
D 172.16.0.0/16 [90/2195456] via 10.1.1 .1, 00:04:57, Serial1/1
D 192.168.1.0/24 [90/2195456] via 10.2.2 .3, 00:04:39, Serial1/0
R2#show ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF , IA

E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route
Gateway of last resort is not set
D 172.16.0.0/16 [90/2195456] via 10.1.1 .1, 00:05:04, Serial1/1
C 10.2.2 .0 is directly connected, Serial1/0
C 10.1.1 .0 is directly connected, Serial1/1
D 192.168.1.0/24 [90/2195456] via 10.2.2 .3, 00:04:46, Serial1/0
可以看到,其實也差不多的.根據拓撲圖來看就會明白.
最後看下R3上的
R3#show ip route

D - EIGRP, EX - EIGRP external, O - OSPF , IA
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route
Gateway of last resort is not set
D 172.16.0.0/16 [90/2707456] via 10.2.2 .2, 00:05:04, Serial1/1
C 10.2.2 .0/24 is directly connected, Serial1/1
D 10.1.1 .0/24 [90/2681856] via 10.2.2 .2, 00:05:04, Serial1/1
D 10.0.0 .0/8 is a summary, 00:05:09, Null0
C 192.168.1.0/24 is directly connected, Ethernet0/0

其實配置EIGRP很簡單的,注意一下它的衡量是根據帶寬和時延來計算的.至於計算的過程比較複雜.
