三层交换VLAN间路由

拓扑图：

img

要求：

  1. 修改主机名为拓扑显示的名称
  2. 创建VLAN
  3. 将相应的端口加入VLAN
  4. 相应的端口配置成Trunk
  5. VLANif接口配置成网络内最后一个可用IP地址
  6. 配置PC机的IP地址，测试不同VLAN的PC是否能正常通信

配置过程：

LSW1:

sys
sys LSW1
un in e
v b 10 20
int e0/0/10
p l a
p d v 10
int e0/0/2
p l a
p d v 10

int e0/0/1
p l t
p t a v 10 20

LSW2:

sys
sys LSW2
un in e
v b 10 20
int e0/0/3
p l a
p d v 20
int e0/0/4
p l a
p d v 20

int e0/0/1
p l t 
p t a v 10 20

LSW3:

sys
sys LSW3
un in e
v b 10 20
int g0/0/1
p l t
p t a v 10 20
int g0/0/2
p l t
p t a v 10 20

int vlanif 10
ip add 192.168.100.62 26
int vlanif 20
ip add 192.168.200.62 26
