多协议路由重发布

实验拓扑：

实验代码如下：

ip address 192.168.12.1 255.255.255.0
no shutdown
exit
int lo1
ip add 192.168.1.1 255.255.255.0
no shutdown
exit
router rip
version 2
no auto-summary
network 192.168.1.0
network 192.168.12.0
end
R2:
enable
config t
hostname R2
int s1/0
ip address 192.168.12.2 255.255.255.0
no shutdown
exit
int s1/1
ip add 192.168.23.1 255.255.255.0
no shutdown
exit
int lo2
ip add 192.168.2.2 255.255.255.0
no shutdown
exit
