使用show up eigrp topology命令来验证EIGRP操作,如下: RouterA# show ip eigrp topology IP-EIGRP Topology Table for AS(100)/ID(10.1.2.1) Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply, r - reply Status, s - sia Status P 10.1.3.0/24, 1 successors, FD is 10514432 via 10.1.2.2 (10514432/28160), Serial0/0 P 10.3.1.0/24, 1 successors, FD is 10639872 via 10.1.2.2 (10639872/384000), Serial0/0 P 10.1.2.0/24, 1 successors, FD is 10511872 via Connected, Serial0/0 P 10.1.1.0/24, 1 successors, FD is 2190 via Connected, Ethernet0/0 P 172.16.1.0/24, 1 successors, FD is 10639872 via 10.1.2.2 (10639872/384000), Serial0/0 (略) 注意前面的字母P,可能出现的字母代号有如下几种: 1.P:代表passive,这个表示稳定网络中的稳定状态 2.A:代表active,当前网络不可用,正处于发送查询状态 3.U:代表update,网络处于等待update包的确认状态 4.Q:代表query,网络处于等待query包的确认的状态 5.stuck-in-active(SIA):持续处于active状态,说明EIGRP网络的收敛发生了问题
