EIGRP路由汇总实验

实验拓扑：

1、R1宣告4条环回口路由。

2、在S1/0口配置ip summary-address eigrp AS号 172.16.8.0 255.255.252.0    #路由传播方向出接口

 

R2#sh ip route
Codes: 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

 

Gateway of last resort is not set

 

172.16.0.0/22 is subnetted, 1 subnets
D 172.16.8.0 [90/2297856] via 12.1.1.1, 00:00:18, Serial1/1
12.0.0.0/24 is subnetted, 1 subnets
C 12.1.1.0 is directly connected, Serial1/1
R2#ping 172.16.8.1

 

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.8.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 16/18/20 ms
