拓扑图
实验步骤
配置三层交换机
en
conf t
hostname S3569
声明两个不同的 Vlan
vlan 10
exit
vlan 20
exit
将端口划分给Vlan
interface fa 0/10
switchport access vlan 10
exit
interface fa 0/20
switchport access vlan 20
exit
配置Vlan
interface vlan 10
ip address 192.168.1.1 255.255.255.0
no shutdown
exit
interface vlan 20
ip address 192.168.3.1 255.255.255.0
no shutdown
exit
开启交换机路由功能
ip routing
启动ospf协议，通告直连的网络
router ospf 1
network 192.168.1.0 0.0.0.255 area 0
network 192.168.3.0 0.0.0.255 area 0
end
show ip route
知识点：
- OSPF宣告是要加反掩码的
- area是自治系统区域的标识。eg：如果全局在一个area中，那么它们属于一个自治系统，也称为单区域自治系统
配置路由器Router0
en
conf t
hostname R0
配置端口
interface f0/0
no shutdown
ip address 192.168.3.2 255.255.255.0
exit
interface s0/0/0
no shutdown
ip address 192.168.4.1 255.255.255.0
clock rate 64000
end
查看当前路由表
show ip route
conf t
设置ospf协议
router ospf 1
network 192.168.3.0 0.0.0.255 area 0
network 192.168.4.0 0.0.0.255 area 0
end
再次查看路由表
show ip route
配置路由器Router1
en
conf t
hostname R2
配置端口
interface s0/0/0
no shutdown
ip address 192.168.4.2 255.255.255.0
exit
interface f0/0
no shutdown
ip address 192.168.2.1 255.255.255.0
end
查看当前路由表
show ip route
conf t
配置ospf
router ospf 1
network 192.168.2.0 0.0.0.255 area 0
network 192.168.4.0 0.0.0.255 area 0
end
再次查看路由表
show ip route
实验结果
查看Router0的路由表，可以看到已经获得了相邻网段的ip：
show ip route
