1、设计实验报告3实验报告设计实验报告3实验报告 实验8 综合组网实验根据组网图，配置生成树协议和链路聚合。并写出相关命令：S1和S2:生成树协议：stp enable链路聚合：interface bridge-aggregation 1link-aggregation mode dynaminter e 1/0/1port link-aggregation group 1inter e 1/0/3port link-aggregation group 1inter bridge-aggregation 1port link-type trunkport trunk permit all因为本实验

2、组网图实际上如下所示：所示本实验只需要配置生成树协议：stp enable链路聚合：inter e 1/0/1port link-type trunkport trunk permit all（或者port trunk permit 3 4 5）请写出核心路由器和核心交换机中的指定路由器和备份指定路由器，并说明为什么？指定路由器是R1，指定的备份路由器是R2，配置命令如下：R1:ip route-stat inter e0/0ip addr 24rp id 11 virtual-ip rp id 11 priority 100ospfdefault-route-advertise cost 1

3、00R2:ip route-stat inter e0/0ip addr 24rp id 11 virtual-ip rp id 11 priority 80ospfdefault-route-advertise cost 20S1:ip route-stat preference 60ip route-stat preference 80ip route-stat preference 100原因说明：首先因为在S1上面配置了路由备份的三条默认路由，而第一条preference最低为60优先下一跳去往，路由表查找去往的下一跳是哪里，发现R1和R2的virtual-ip都是，因此选择prior

4、ity为100优先级更高的R1进行转发。所以R1是主路由器，R2是备份路由器。（实验过程中核心交换机S1和汇聚交换机S2的不单独配置前往外网的默认路由，只需要在出口路由器R1和R2上，将默认路由引入至OSPF，并通过OSPF传播给S1和S2）而当S1路由备份失效时候，即静态路由失效时，由于R1和R2都启用了OSPF协议，并且R1的cost值比较小，优先选择R1，当R1失效时候才会选择R2路由器，因此R1是主出口路由器，R2是备份路由器。写出访问控制列表的相关命令：PCA的ip地址：/24 网关：PCB的ip地址：/24 网关：R1:acl number 201 rule 0 permit so

5、urce 55rule 1 permit source 55rule 2 denyR2:acl number 201rule 0 deny source 55rule 1 permit source 55rule 2 deny 当R1路由器正常时，PCA和PCB能够正常访问互联网，并且网路中的路由器和交换机是无法ping到外网的。当关闭R1-S2-Inter这条路线的R1上端口e0/1时候，由于路由器R2的规则阻止，网段访问互联网，即PCA可以访问换联网，而PCB无法访问。将路由器R1的E1接口断掉，截获并分析p Trap报文，写出报文的字段名和字段值，然后重新连接，通过网络管理服务器查看路由
