实验目的:
某公司拥有两个部门,市场部和人事部门,市场部和人事部的IP地址分别为10.1.11.0/24、10.1.21.0/24两个IP网段。市场部属于vlan11,人事部属于vlan21。现在需要在SW2上配置802.1x认证,实现终端用于只有认证成功后,才能访问网络中的资源。
(本实验使用真实设备,其中radius服务器需要自行搭建)

[SW1-ospf-1-area-0.0.0.0]network 10.1.60.254 0.0.0.0
[SW1-ospf-1-area-0.0.0.0]network 10.1.200.29 0.0.0.0
SW2的配置:
[SW2]ospf
[SW2-ospf-1]area 0
[SW2-ospf-1-area-0.0.0.0]network 10.1.11.254 0.0.0.0
[SW2-ospf-1-area-0.0.0.0]network 10.1.21.254 0.0.0.0
[SW2-ospf-1-area-0.0.0.0]network 10.1.200.30 0.0.0.0
[SW2]dhcp enable
Info: The operation may take a few seconds. Please wait for a moment. done.
