某一学校拟对单位网络进行规划设计。请根据下列具体要求给出你的网络规划和设计方案,并在HCL模拟器上完成配置。图中PC_1、PC_2、r1、r2、r3、SW1为局域网内的设备,其中r2、r3为自治系统边界路由器;r4模拟ISP的一路由器, PC_3、PC_4、r5模拟广域网上的设备。
实验要求
(1) 请根据下面拓扑图,完善表1(网络连接规划表)、表2(设备明细表)和表3 (IP规划表)
(2)IP地址规划
1)IP 地址掩码长度均使用24位; 外网要使用公网上可以使用的IP地址。请填写表3。
2)IP地址的第三段为学号的最后2位,内网使用ospf协议,ospf的进程号使用学号的最后3位, BGP进程号按照图1要求配置。
(3) 根据表3中的规划,作好各设备的IP地址配置,在r1、r2和r3上配置ospf协议,在r2、r3、r4和r5上配置BGP协议,并用display ip routing-table显示r2上的路由表,给出执行结果截图,使用display bgp routing-table ipv4显示r5的bgp路由表,给出执行结果截图。
(4)路由引入
在内网r2和r3两台路由器上实现路由引入,将ospf路由引入BGP路由,将BGP路由引入ospf路由。并用display ip routing-table显示r2上的路由表,给出执行结果截图。
(5) 利用路由策略实现路由过滤,在路由器r1上配置路由过滤策略实现PC_1和PC_2不可访问PC_4的流量,给出关键配置语句。并在PC_1上ping PC_4,给出执行结果截图,并做相应简要说明。
