1:网络拓扑图：

-------------------------------------------------------------//xx的分解线

2.网络连接：

Router1 E0/0 <----> Switch1 F0/1
Switch1 F0/2 <----> Switch2 F0/2
XPC P0/0 <----> Switch2 F0/0
VPCS V0/1 <----> Switch2 F0/1
-------------------------------------------------------------//xx的分解线

3.命令的配置

二层交换机:
vlan database
vlan 2
vlan 3
exit
conf t
int f0/0
switchport access vlan 2
exit
int f0/1
switchport access vlan 3
exit
int f0/2
switchport mode trunk
exit

三层交换机;
vlan database
vlan 2
vlan 3
conf t
ip routing
int vlan 2
ip add 192.168.1.1 255.255.255.0
no shut
exit
int vlan 3
ip add 192.168.2.1 255.255.255.0
no shut
exit
int f0/2
no shut
exit
int f0/2
switchport mode trunk
exit
int f0/1
no switchport
ip address 10.1.1.1 255.255.255.252
no shut
exit
ip route 0.0.0.0 0.0.0.0 10.1.1.2
show ip route

路由器的配置
conf t
int e0/0
ip add 10.1.1.2 255.255.255.252
no shut
exit
ip route 192.168.1.0 255.255.255.0 10.1.1.1
ip route 192.168.2.0 255.255.255.0 10.1.1.1
show ip route
show adjacency detail

虚拟PC的配置
ip 192.168.2.5 192.168.2.1 24
-------------------------------------------------------------//xx的分解线

使用三层交换机的来实现简单的网络拓扑！！
