RIP配置
（1）rip配置
R1：
rip 1
version 2
network 192.168.1.0
network 12.0.0.0
RIP需要宣告主类网络，比如12.1.1.1/24宣告12.0.0.0
R2：
rip 1
version 2
network 192.168.10.0
network 23.0.0.0
network 12.0.0.0
R3：
rip 1
version 2
network 192.168.5.0
network 23.0.0.0
（2）rip信息查询
[R2]dis rip 1 route
Route Flags : R - RIP
A - Aging, G - Garbage-collect
---------------------------------------------------------
Peer 12.1.1.1 on Ethernet0/0/0
Destination/Mask Nexthop Cost Tag Flags Sec
192.168.1.0/24 12.1.1.1 1 0 RA 6
Peer 23.1.1.3 on Ethernet0/0/1
Destination/Mask Nexthop Cost Tag Flags Sec
192.168.5.0/24 23.1.1.3 1 0 RA 17
（3）路由信息查询
[R2] dis ip routing-table
Route Flags: R - relay, D - download to fib
--------------------------------------------------------------
Routing Tables: Public
Destinations : 10 Routes : 10
Destination/Mask Proto Pre Cost Flags NextHop Interface
12.1.1.0/24 Direct 0 0 D 12.1.1.2 Ethernet0/0/0
12.1.1.2/32 Direct 0 0 D 127.0.0.1 Ethernet0/0/0
23.1.1.0/24 Direct 0 0 D 23.1.1.2 Ethernet0/0/1

192.168.1.0/24 RIP 100 1 D 12.1.1.1 Ethernet0/0/0
192.168.5.0/24 RIP 100 1 D 23.1.1.3 Ethernet0/0/1
