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 1
link-aggregation mode dynamic
inter e 1/0/1
port link-aggregation group 1
inter e 1/0/3
port link-aggregation group 1
inter bridge-aggregation 1
port link-type trunk
port trunk permit vlan all
因为本实验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 1/0/1
port link-type trunk
port trunk permit vlan all（或者port trunk permit vlan 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-static
inter e0/0
ip addr 24
vrrp vrid 11 virtual-ip
vrrp vrid 11 priority 100
ospf
default-route-advertise cost 100
[R2]:
ip route-static
inter e0/0
ip addr 24
vrrp vrid 11 virtual-ip
vrrp vrid 11 priority 80
ospf
default-route-advertise cost 200
[S1]:
ip route-static preference 60
ip route-static preference 80
ip route-static 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priority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 2001
rule 0 permit source 55
rule 1 permit source 55
rule 2 deny
[R2]:
acl number 2001
rule 0 deny source 55
rule 1 permit source 55
rule 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->Internet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器状态。

每台设备上配置专用的网络管理地址有什么好处？
答：
因为网管软件需要按照ip地址添加设备，因此每台设备都配置专用网络管理地址可以方便的被网络管理工具实时监控和管理。方便网络管理工具对设备进行故障管理，配置管理，计费管理，性能管理，安全管理。
请附上全部网络设备的最终配置
PS：假如主机ping不通 ，而主机能ping通R1的接口地址，R1能ping通
删掉vlan1的DHCP即可：
