EIGRP的配置

基本配置

Router(config)#router eigrp 50
Router(config-router)#network 172.16.0.0
Router(config-router)#network 10.1.1.1
Router(config-router)#network 10.1.2.1
Router(config-router)#network 10.1.3.1
Router(config-router)#network 10.1.4.1

其它命令

查看邻居关系

Router#sh ip eigrp 50 neighbors
EIGRP-IPv4 Neighbors for AS(50)
H   Address                 Interface       Hold Uptime   SRTT   RTO  Q  Seq
                                            (sec)         (ms)       Cnt Num
1   172.16.1.6              Et0/1             14 00:16:30    9   200  0  22
0   172.16.1.1              Et0/0             12 00:16:54    5   200  0  20

确认路由

Router#sh ip route
Codes: L - local, C - connected, S - static, 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
       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, + - replicated route

Gateway of last resort is not set

只看EIGRP路由

Router#sh ip route eigrp
Codes: L - local, C - connected, S - static, 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
       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, + - replicated route
