EIGRP配置命令

 

 

 

metric=(带宽最小值+延迟的和）*256

show run的带宽要乘以10的七次方          延迟值要除以10

等价负载（metric值相等）

非等价负载分担（AD<=FD)

 

R1(config)#router eigrp 100 //100为自制系统号，邻居之间必须一致

R1(config-router)#network 1.1.0.0 0.0.255.255 //使某些接口运行eigrp

R1(config-router)#metric weights 0 1 0 1 0 0 // 第一个必须为0，后面的是k1,k2,k3,k4,k5

R1(config-router)#variance 2 //设置非等价负载分担的系数为“2”

R1(config-router)#eigrp stub ? //设置本设备为eigrp末节设备，默认后面跟connected,summary 参数

 connected      Do advertise connected routes

 leak-map       Allow dynamic prefixes based on the leak-map

 receive-only   Set IP-EIGRP as receive only neighbor

 redistributed Do advertise redistributed routes

 static         Do advertise static routes

 summary        Do advertise summary routes

 <cr>

 

R1(config-if)#ip authentication mode eigrp 100 md5 //接口下开启eigrp认证

R1(config-if)#ip authentication key-chain eigrp 100 ccxx //接口下调用名为"ccxx"钥匙链

R1(config)#key chain ccxx //建立名为"ccxx"钥匙链

R1(config-keychain)#key 1 //建立key 1

R1(config-keychain-key)#key-string a //定义key 1的密码是“a”

R1(config-keychain-key)#exit

R1(config-keychain)#key 2 //建立key 2

R1(config-keychain-key)#key-string b //定义key 1的密码是“a”

R1(config-keychain-key)#end

 

 

校验命令:

R1#show ip protocol

R1#show ip eigrp interface

R1#show ip eigrp neighbors

R1#show ip eigrp topology

R1#show key chain

R1#show ip route eigrp

R1#debug eigrp packets

 

eigrp 建立邻居必要条件：

1.network    show ip eigrp interfaces/ show ip protocol / show run/

2.AS     show ip protocol

3.Metric weight     show ip protocol

4.Authentication     show run int f0/0   show key chain
