网络自测试
项目：小试牛刀
完成以下测试
#######完成训练################################################
要求：
1 相同VLAN之间要互通，不同VLAN之间也要互通；
2 蓝色（深蓝 上边）背景区域为外网，青色（淡蓝，下边）背景区域为内网；
3 外网使用HSRP配置加浮动路由，内网自己规划；
4 各VLAN使用的地址段：*.0，其中的*号为VLAN号码；
5 各VLAN的网关地址为*.254，如果是使用HSRP，网关为*.250；
6 各VLAN的根交换机要求：
Core-1：VLAN/10.20的根；
Core-2：VLAN60的根；
Core-3：VLAN30.40的根
Core-4：VLAN50的根
6 各VLAN的主网关：
Core-1：VLAN10.20的网关；
Core-2：VLAN60的网关；
Core-3：VLAN30.40的网关；
Core-4：VLAN50的网关。
7 有两条链路 配制成以太网通道。
8 各终端使用DHCP服务器自动配置IP。
9 服务器的IP手动配置为192.168.50.253/24和192.168.50.254/24 #没错你没看错～
10 实现在家(外网11.11.11.11/24)做饭的IT男用自己的苹～果～笔记本 telnet 远程控制内网核心交换机Core-1
11 外网不能ping通 内网
内网通公网 IP 100.10.10.1/24
确定划分vlan IP为192.168.*.0/24
帮助命令
debug ip icmp #危险操作仅限测试用，现实网络慎敲
undebug ip icmp #解除上面的命令
show cdp neighbors #查看直连端口信息
reload #重启
write #保存配置
erase startup-config #删除保存的配置
配置思路：
1配置终端主机
2 交换网络互通
3 路由网络互通
4 内外网互通
