配置一下路由器接口
R1#sh ip int b
Interface IP-Address OK? Method Status Protocol
Serial1/0 unassigned YES unset administratively down down
Serial1/1 unassigned YES unset administratively down down
Serial1/2 unassigned YES unset administratively down down
Serial1/3 unassigned YES unset administratively down down
R1#
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#int s1/1
R1(config-if)#ip address 12.12.12.1 255.255.255.252
R1(config-if)#no sh
R1(config-if)#
*Mar 1 00:05:29.123: %LINK-3-UPDOWN: Interface Serial1/1, changed state to up
*Mar 1 00:05:30.123: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/1, changed state to up
R1(config-if)#
R1#sh ip int b
Interface IP-Address OK? Method Status Protocol
Serial1/0 unassigned YES unset administratively down down
Serial1/1 12.12.12.1 YES manual up down
Serial1/2 unassigned YES unset administratively down down
Serial1/3 unassigned YES unset administratively down down
R1#
中间路由器
R2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#int s1/0
R2(config-if)#ip ad
R2(config-if)#ip address 12.12.12.2 255.255.255.252
R2(config-if)#no sh
R2(config-if)#
*Mar 1 00:07:36.079: %LINK-3-UPDOWN: Interface Serial1/0, changed state to up
*Mar 1 00:07:37.079: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/0, changed state to up
R2(config-if)#do ping 12.12.12.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 12.12.12.1, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
直连怎么可能没通，再来
R2(config-if)#do ping 12.12.12.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 12.12.12.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/24/32 ms
好了
R2#sh ip int br
Interface IP-Address OK? Method Status Protocol
Serial1/0 12.12.12.2 YES manual up up
Serial1/1 unassigned YES unset administratively down down
Serial1/2 unassigned YES unset administratively down down
Serial1/3 unassigned YES unset administratively down down
R2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#int s1/1
R2(config-if)#ip add
R2(config-if)#ip address 23.23.23.1 255.255.255.252
R2(config-if)#no sh
R2(config-if)#
*Mar 1 00:10:07.467: %LINK-3-UPDOWN: Interface Serial1/1, changed state to up
*Mar 1 00:10:08.467: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/1, changed state to up
R2(config-if)#
R2#sh ip int b
Interface IP-Address OK? Method Status Protocol
Serial1/0 12.12.12.2 YES manual up up
Serial1/1 23.23.23.1 YES manual up down
Serial1/2 unassigned YES unset administratively down down
Serial1/3 unassigned YES unset administratively down down
R2#
2个ip都好了
最右面的
R3(config)#int s1/0
R3(config-if)#ip address 23.23.23.2 255.255.255.252
R3(config-if)#no sh
R3(config-if)#
*Mar 1 00:12:58.627: %LINK-3-UPDOWN: Interface Serial1/0, changed state to up
*Mar 1 00:12:59.627: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/0, changed state to up
R3(config-if)#
R3#sh ip int b
Interface IP-Address OK? Method Status Protocol
Serial1/0 23.23.23.2 YES manual up up
Serial1/1 unassigned YES unset administratively down down
Serial1/2 unassigned YES unset administratively down down
Serial1/3 unassigned YES unset administratively down down
R3#ping 23.23.23.1

R3#
开始配置rip
R1(config)#router rip
R1(config-router)#version 2
R1(config-router)#no auto-summary
R1(config-router)#network 12.0.0.0
R2(config)#router rip
R2(config-router)#version 2
R2(config-router)#no auto-summary
R2(config-router)#network 12.0.0.0

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
23.0.0.0/30 is subnetted, 1 subnets
R 23.23.23.0 [120/1] via 12.12.12.2, 00:00:14, Serial1/1
12.0.0.0/30 is subnetted, 1 subnets
C 12.12.12.0 is directly connected, Serial1/1
R1#ping 23.23.23.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 23.23.23.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/54/76 ms
开一下debug看事件
R1#debug ip rip data
R1#debug ip rip database
RIP database events debugging is on
R1#debug ip rip events
RIP event debugging is on
R1#debug ip rip trigger
RIP trigger debugging is on
R1#debug ip rip
其余两个常用命令
R1#sh ip ro
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
23.0.0.0/30 is subnetted, 1 subnets
R 23.23.23.0 [120/1] via 12.12.12.2, 00:00:02, Serial1/1
12.0.0.0/30 is subnetted, 1 subnets
C 12.12.12.0 is directly connected, Serial1/1
R1#
