简单综合实验（企业局域网）
1、基本配置（交换机、路由器安全登陆管理、端口连接描述、配置vlan1地址）
Username pinginglab password ccnp
Enable password cisco
Line console 0
Login local
Logging synchronous
Exec-timeout 0 0
Line vty 0 4
Login local
Transport input ssh
Transport output ssh
Line vty 5 15
Transport input none
Transport output none
int f0/1

Network 0.0.0.0 255.255.255.255
ip route 0.0.0.0 0.0.0.0 s0/1/0
redistribute static
