实验步骤：
1， 继续上一部分实验，在两台路由器上配置 EIGRP 认证： NJ(config)#key chain cisco NJ(config-keychain)#key 1 NJ(config-keychain-key)#key-string juniper NJ(config-keychain-key)#exit NJ(config-keychain)#exit NJ(config)#interface serial 1 NJ(config-if)#ip authentication key-chain eigrp 100 cisco NJ(config-if)#ip authentication mode eigrp 100 md5

实验步骤：
1， 按图示配置好各台路由器的各个接口； 2， 在两台路由器上启用 EIGRP 协议； 3， 查看两台路由器的路由表，NJ 学到的是具体路由（因为 SH 不是主类网络边界） ，SH 学 到的是汇总路由（因为 NJ 是主类网络边界） ：
NJ#show ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP 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 172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks 172.16.0.0/16 is a summary, 00:03:44, Null0 172.16.1.0/24 is directly connected, Serial1 10.0.0.0/8 is variably subnetted, 3 subnets, 2 masks 10.0.0.0/8 is a summary, 00:03:44, Null0 10.2.2.0/24 is directly connected, Loopback1 10.1.1.0/24 is directly connected, Loopback0 192.168.1.0/24 [90/2297856] via 172.16.1.2, 00:03:32, Serial1 192.168.2.0/24 [90/2297856] via 172.16.1.2, 00:03:33, Serial1

4， 在两台路由器上关闭自动汇总并配置手工汇总：
NJ(config)#router eigrp 100 NJ(config-router)#no auto-summary NJ(config-router)#exit NJ(config)#interface serial 1 NJ(config-if)#ip summary-address eigrp 100 10.0.0.0 255.252.0.0
5， 再次查看两边的路由表，发现已出现手工汇总条目： NJ#show ip route Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP 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 172.16.0.0/24 is subnetted, 1 subnets 172.16.1.0 is directly connected, Serial1 10.0.0.0/8 is variably subnetted, 3 subnets, 2 masks 10.0.0.0/14 is a summary, 00:00:26, Null0 10.2.2.0/24 is directly connected, Loopback1 10.1.1.0/24 is directly connected, Loopback0 192.168.0.0/22 [90/2297856] via 172.16.1.2, 00:00:26, Serial1
EIGRP 手工汇总＋认证实验
