实验拓扑
实验要求
1、按照图示配置IP地址
2、sw1和sw2之间的直连链路配置链路聚合
3、 公司内部业务网段为VLAN10和VLAN20; VLAN 10是市场部,vlan20是技术部,要求对VLAN进行命名以便识别;PC1属于vlan10,PC2属于vlan20,vlan30用于SW1和SW2建立OSPF邻居;VLAN111为SW1和R1的互联vlan,vlan222为sw2和R2的互联vlan
4、所有交换机相连的端口配置为TRUNK,允许相关流量通过
5、交换机连接PC的端口配置为边缘端口
6、在SW1上配置DHCP服务,为vlan10和vlan20的PC动态分配IP地址,网关和DNS地址;要求vlan10的网关是192.168.1.252,vlan20的网关是192.168.2.253
7、按图示分区域配置OSPF实现公司内部网络全网互通,ABR的环回口宣告进骨干区域;业务网段不允许出现协议报文
8、R1上配置默认路由指向互联网,并引入到OSPF
9、R1通过双线连接到互联网,配置PPP-MP,并配置双向CHAP验证
10、配置EASY IP,只有业务网段192.168.1.0/24和192.168.2.0/24 的数据流可以通过R1访问互联网
11、R1开启TELNET远程管理,使用用户ABC登录,密码ABC,只允许技术部远程管理R1
实验解法
1、给PC配置IP地址
为R1配置IP地址

交换机连接PC的端口配置为边缘端口
边缘端口(Edge Port) 是生成树协议(STP, Spanning Tree Protocol)中的一个概念,特指那些直接连接到终端设备(如PC、服务器等)的端口,而不是连接到其他交换机或网桥的端口。在STP中,边缘端口具有一些特殊的属性和行为,以优化网络性能和避免不必要的延迟。

按图示分区域配置OSPF实现公司内部网络全网互通,ABR的环回口宣告进骨干区域;业务网段不允许出现协议报文
命令的大致意思是将VLAN 10的接口设置为“静默接口”(silent interface)。当设置为静默接口时,该接口将不会发送与该路由协议相关的路由更新或Hello报文。
