路由器和交换机的综合实验(1)
1. 按拓扑图所示,完成各网络设备的基本配置。
2. 在四台交换机上配置MSTP协议,并将VLAN10,VLAN30映射到实例1,S3750-1为实例1的根,将VLAN20,VLAN40映射到实例2,S3750-1为实例2的根。,实现阻断网络环路,并实现数据流量的负载均衡。
3. 在S3750-1和S3750-2上配置VRRP,S3750-1和S3750-2分别对VLAN10—VLAN40启用两个VRRP组,实现负载均衡。
4. 在RA和RB上开启RIPV2协议,在RB、RC、RD、S3750-1、S3750-2上开启OSPF协议,实现各路由域内部的互通。
5. 在RB上配置去往ISP的默认路由,并在RB上配置路由重发布,实现全网的互通。
6. 在S3750-1和S3750-2上的SVI上实现如下访问控制:VLAN10为经理部,可以访问其他各个VLAN;经理部设有FTP服务器一台,地址为192.168.10.1/24,只有VLAN20、VLAN30、VLAN40的成员在工作时间(每周一至周五8:00-16:00)可以访问该FTP服务器的FTP服务,其余时间不可以访问。
7. 在RB上实现如下访问控制:所有用户在工作时间均不可以访问Internet,其他时间可以。
8. 在RB上配置策略路由,VLAN10和VLAN30的数据从loopback0转发,VLAN20和VLAN40的数据从loopback1转发。
在RB上配置NAT转换,实现内网的用户可以访问Internet,该公司申请到的公有地址是200.1.1.2/24-200.1.1.6/24。
