1.RIP
实验要求：在R3中将默认路由重发布进RIP。
基本配置：
R1:
R1(config)#router rip
R1(config-router)#version 2
R1(config-router)#network 12.0.0.0
R1(config-router)#no auto-summary
R2:
R2(config)#router rip
R2(config-router)#version 2
R2(config-router)#network 12.0.0.0
R2(config-router)#network 23.0.0.0
R3:
R3(config)#router rip
R3(config-router)#version 2
R3(config-router)#network 23.0.0.0
方法一、
R3:
R3(config)#router rip
R3(config-router)#redistribute static metric 1
R3(config)#ip route 0.0.0.0 0.0.0.0 172.16.1.2
方法二、
R3:
R3(config)#router rip
R3(config-router)#default-information originate
实验结果：
R1#sh ip route
12.0.0.0/24 is subnetted, 1 subnets
C 12.1.1.0 is directly connected, FastEthernet0/0
R 23.0.0.0/8 [120/1] via 12.1.1.2, 00:00:24, FastEthernet0/0
R* 0.0.0.0/0 [120/2] via 12.1.1.2, 00:00:24, FastEthernet0/0
R2#sh ip route
12.0.0.0/24 is subnetted, 1 subnets
C 12.1.1.0 is directly connected, FastEthernet0/0
23.0.0.0/24 is subnetted, 1 subnets
C 23.1.1.0 is directly connected, FastEthernet0/1
R* 0.0.0.0/0 [120/1] via 23.1.1.2, 00:00:27, FastEthernet0/1
R1#ping 172.16.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/20/20 ms
2.EIGRP
实验要求：在R3中将默认路由重发布进EIGRP
基本配置：
R1:
R1(config)#router eigrp 100
R1(config-router)#network 12.0.0.0
R1(config-router)# no auto-summary
R2:
R2(config)#Router eigrp 100
R2(config-router)#network 12.0.0.0
R2(config-router)#network 23.0.0.0
R3:
R3(config)#Router eigrp 100
R3(config-router)#network 23.0.0.0
R3(config-router)#no auto-summary
R3(config-router)#network 172.16.1.0 0.0.0.255
R3(config)#ip default-network 172.16.0.0
