5、思考
VLAN 间的通信可以利用单臂路由的方式实现，，，那么利用单臂路由实现数据转发会存在哪些潜在问题？？该如何解决？
解答：
利用单臂路由实现数据转发会存在两个问题：
　　1.路由器和交换机是通过一条链路连接，，容易成为网络单点故障，导致 VLAN 之间的通信中断；
　　2.各个 VLAN之间的通信都是由 “单臂”链路承载， “单臂”链路可能会成为流量传输的瓶颈；；利用三层交换机实现VLAN间路由可以解决 “单臂路由”存在的问题。

查看接口状态

4、验证

5、思考
试问三层交换机与路由器实现三层功能的方式是否相同，为什么？
解答：
不相同。因为三层交换机上面的物理接口都是2层接口，需要在三层交换机上配置 VLANIF 接口。VLANIF 接口是基于网络层的接口，可以配置IP地址，借助于VLANIF接口，三层交换机就能实现路由转发功能。

端口角色：

Root Port：根端口
Alternate Port：可替代端口
DISCARDING：为丢弃端口，不转发流量

5、思考
在什么场景下，选举根端口、指定端口时会比较到端口ID?
解答：当进行生存树BPUD比较是，，根桥ID、开销值、发送桥ID前三个参数依次都相同时，，这时就需要比较发送者的端口ID。

4、测试

5、思考
S4交换机的E0/0/2接口关闭之后，E0/0/3会成为新的根端口，如果此时S3交换机的指定端口E0/0/3也关闭掉，S4交换机上会发生端口角色或状态的改变吗?如果边缘端口收到BPDU，此端口还是边缘端口吗?

6、提示
在RSTP中，Alternate 端口和 Backup 端口角色所对应的最终端口状态都是Discarding。区别是Altermate端口用于为根端口做备份，而Backup端口用于为本交换机上的指定端口做备份，所以当相应的根端口或指定端口断掉后，备份端口会立即承担原有的根端口或指定端口的角色，开始转发数据。
RSTP 协议是对STP的升级，它重新划定端口的角色及状态，使用更快速的握手协商机制，降低了收敛时间，使它成为继 STP 协议后首选的生成树协议，不足之处就是在同一网络内的交换机上所有的VLAN共用同样的拓扑，此时可以使用MSTP 来优化。

mstp

原理：
RSTP在STP基础上进行了改进，实现了网络拓扑快速收敛。但RSTP和STP还存在同一个缺陷，即由于局域网内所有的 VLAN 共享一棵生成树，链路被阻寒后将不承载任何流量，造成带宽浪费，因此无法在 VLAN 间实现数据流量的负载均衡，还有可能造成部分VLAN的报文无法转发。
通过MSTP 把一个交换网络划分成多个域，每个域内形成多棵生成树，生成树之间彼此独立。每个域叫做一个MST域(Multiple Spanning Tree Region，MST Region)，每棵生成树叫做一个多生成树实例MSTI(MultipleSpanningTreeInstance)。实例内可以包含多个VLAN。通过将多个VLAN映射到同一个实例内，可以节省通信开销和资源占用率。MSTP 各个实例拓扑的生成树计算相互独立，通过这些实例可以实现负载均衡。把多个相同拓扑结构的 VLAN 映射到一个实例里，这些VLAN在端口
上的转发状态取决于端口在对应MSTP实例的状态。MSTP通过设置VLAN 映射表(即VLAN和MSTI的对应关系表)，把VLAN和MSTI联系起来每个VLAN只能对应一个MSTI即同一VLAN的数据只能在一个MSTI中传输，而一个MSTI可能对应多个VLAN。

可以观察到，目前VLAN10的流量都从S3的E0/0/1接口转发
可以观察到，目前VLAN20的流量都从E0/0/2接口转发。
至此，完成了 MSTP的多实例的配置，并达到了流量分担的目的，有效地利用了网络资源，也同时使得S3的两条上行链路可以互相备份。

MSTP并不会为每个MSTI生成、发送一份独立的BPDU,而是通过在ISTBPDU中的Mrecord 字段反映VLAN与MSTI的映射关系。

5、思考
当MSTP和RSTP混合使用的时候，如何选举根桥?
解答：MSTP协议可以把支持MSTP的交换机和不支持MSTP交换机划分成不同的区域，分别称作MST域和SST域。在MST域内部运行多实例化的生成树，在MST域的边缘运行RSTP兼容的内部生成树IST（Internal Spanning Tree）。对于RSTP来说可以将MSTP域内的设备看成一台RSTP设备来进行正常的根桥选举。

其他交换技术

GVRP

GVRP(GARPVLAN Registration Protocol)，中文名为GARPVLAN注册协议，是GARP(Generic Attribute Registration Protocol，通用属性注册协议)的一种应用，用于注册和注销VLAN属性。使得交换机之间能够相互交换 VLAN配置信息，动态创建和管理VLAN。用户只需要对少数交换机进行 VLAN 配置即可动态地传播 VLAN信息。
手工配置的VLAN 称为静态VLAN，通过GVRP协议创建的VLAN称为动态VLAN。GVRP有3种注册模式，不同的模式对静态VLAN和动态VLAN的处理方式也不同。

Normal模式:允许该接口动态注册注销VLAN,传播动态VLAN以及静态VLAN信息;
Fixed模式:禁止该接口动态注册、注销VLAN，只传播静态VLAN信息。即被设置成为该模式下的 Trunk 接口，即使允许所有 VLAN通过，实际通过的VLAN也只能是手动配置的那部分;
Forbidden模式:禁止该接口动态注册、注销VLAN，不传播任何除VLAN1以外的任何 VLAN信息。即被设置成为该模式下的Trunk 接口,即使允许所有VLAN通过实际通过的VLAN也只能是VLAN1。

说明：
协议可以在交换机上动态的创建 VLAN，并控制 Trunk 接口允许通过的LAN列表，但并不能自动将用户端口划分至相应VLAN中。

[S3]display voice-vlan	
...

验证：

发现网络不通，解决方案1、可以在S3主机新建vlan10 20;2、把该接口模式切换回normal

命令备注：

5、思考
GVRP能够应用在Hybrid类型的接口上吗?
并不能,hybrid作为灵活性较强的接口类型,再到多数情况下可以替代trunk和access接口.但是偏偏gvrp只认trunk不认hybrid。

[S2]monitor-link group 1
[S2-mtlk-group1]port GigabitEthernet 0/0/1 uplink 
[S2-mtlk-group1]port Ethernet 0/0/3 downlink 

#Monitor Link回切时间默认为3s，修改为10s
[S2-mtlk-group1]timer recover-time 10

5、思考
Smart Link和Monitor Link的联合使用可以确保链路出现故障后及时地切换，如果所有链路都正常，是否所有数据都只能通过主链路转发?

Eth-Trunk链路聚合

在没有使用 Eth-Trunk 前，百兆以太网的双绞线在两个互连的网络设备间的带宽仅为100Mbit/s。若想达到更高的数据传输速率，则需要更换传输媒介，使用千兆光纤或升级成为千兆以太网。这样的解决方案成本较高。如果采用 Eth-Trunk 技术把多个接口捆绑在一起，则可以以较低的成本满足提高接口带宽的需求。例如，把3个100Mbit/s 的全双工接口捆绑在一起，就可以达到300Mbit/s的最大带宽。Eth-Trunk是一种捆绑技术，它将多个物理接口捆绑成一个逻辑接口，这个逻辑接口就称为Eth-Trunk接口，捆绑在一起的每个物理接口称为成员接口。Eth-Trunk 只能由以太网链路构成。Trunk的优势在于:

负载分担，在一个Eth-Trunk 接口内，可以实现流量负载分担;
提高可靠性，当某个成员接口连接的物理链路出现故障时，流量会切换到其他可用的链路上，从而提高整个Trunk链路的可靠性;
增加带宽，Trunk接口的总带宽是各成员接口带宽之和。

Eth-Trunk 在逻辑上把多条物理链路捆绑等同于一条逻辑链路，对上层数据透明传输。所有Eth-Trunk中物理接口的参数必须一致，Eth-Trunk链路两端要求一致的物理参数有:Eth-Trunk链路两端相连的物理接口类型、物理接口数量、物理接口的速率、物理接口的双工方式以及物理接口的流控方式。

Eth-Trunk工作模式可以分为两种:

手工负载分担模式:需要手动创建链路聚合组，并配置多个接口加入到所创建的Eth-Trunk中;
静态LACP模式该模式通过LACP协议协商Eth-Trunk 参数后自主选择活动接口。

4、备注
当一条高优先级的接口因故障切换为非活动状态而后又恢复时，只有使能抢占功能后高优先级的接口将重新成为活动接口。默认情况下抢占功能是关闭的，需要在eth-trunk 接口下手动开启并根据实际情况配置相应的抢占时延 (默认为30s)。

5、思考
当接口数超出最大负载闯值时，剩余接口是否转发流量?

静态路由

静态路由及默认路由基本配置

静态路由是指用户或网络管理员手工配置的路由信息。当网络的拓扑结构或链路状态发生改变时，需要网络管理人员手工修改静态路由信息。相比于动态路由协议，静态路由无需频繁地交换各自的路由表，配置简单，比较适合小型、简单的网络环境。
静态路由不适合大型和复杂的网络环境，因为当网络拓扑结构和链路状态发生变化时，网络管理员需要做大量的调整，且无法自动感知错误发生，不易排错。
默认路由是一种特殊的静态路由,当路由表中与数据包目的地址没有匹配的表项时数据包将根据默认路由条目进行转发。默认路由在某些时候非常有效，如在末梢网络中默认路由可以大大简化路由器配置，减轻网络管理员的工作负担。

4、备注

5、思考

RIP

RIP(Routing Information Protocol，路由协议)作为最早的距离矢量IP路由协议，也是最先得到广泛使用的一种路由协议，采用了 Bellman-Ford 算法，其最大的特点就是配置简单。
RIP协议要求网络中每一台路由器都要维护从自身到每一个目的网络的路由信息。RIP协议使用跳数来衡量网络间的“距离”:从一台路由器到其直连网络的跳数定义为 1，从-台路由器到其非直连网络的距离定义为每经过一个路由器则距离加1。“距离”也称为“跳数”RIP 允许路由的最大跳数为15，因此，16 即为不可达。可见RIP 协议只适用于小型网络。
目前RIP有两个版本，RIPV1和 RIPv2，RIPV2针对RIP1进行扩充，能够携带更多的信息量，并增强了安全性能。RIPv1和RIPv2都是基于UDP的协议，使用UDP520号端口收发数据包。

<R1>undo debugging rip 1

与RIPv1中使用debuging 命令所查看的信息进行对比，可以明显区分出 RIPv1和RIPv2的不同;

RIPv2的路由信息中携带了子网掩码;
RIPv2的路由信息中携带了下一跳地址，标识一个比通告路由器的地址更好的下跳地址。换句话说，它指出的地址，其度量值(跳数)比在同一个子网上的通告路由器更靠近目的地。如果这个字段设置为全0(0.0.0.0)，说明通告路由器的地址是最优的下一跳地址;
RIPv2默认采用组播方式发送报文，地址为224.0.0.9。

配置RIPv2的认证

配置协议的认证可以降低设备接受非法路由选择更新消息的可能性，也可称为“验证”。非法的更新消息可能来自试图破坏网络的攻击者，或试图通过欺骗路由器发送数据到错误的目的地址的方法来捕获数据包。RIPv2 协议能够通过更新消息所包含的口令来验证某个路由选择消息源的合法性，有简单和 MD5密文两种验证方式。
简单验证是指在认证的消息当中所携带的认证口令是以明文传输的，可以通过抓包软件抓取到数据包中的密码。
MD5密文验证是一种单向消息摘要 (message digest)算法或安全散列函数(secure hash function)，由 RSA Date Security,Inc 提出。有时 MD5 也被作为一个加密校验和cryptographic checksum)。MD5算法是通过一个随意长度的明文消息(例如一个RIPv2的更新消息)和口令计算出一个128位的 hash值。hash值类似“指纹”，这个“指纹”随同消息一起传送，拥有相同口令的接收者会计算它自己的 hash 值，如果消息的内容没有被更改，接收者的 hash 值应该和消息发送者的hash 值相匹配

4、思考
在本实验中，如果现在公司总部配置的区域不是骨干区域0，而是其他非骨干区域,会出现什么现象?
解答：这样做了之后会导致公司各个区域之间互相不能通信，因为跨区域路由只能由区域0的边界ABR进行类型3汇总得到。

配置OSPF的认证

OSPF支持报文验证功能，只有通过验证的报文才能接收，否则将不能正常建立邻居关系。OSPF 协议支持两种认证方式一区域认证和链路认证。使用区域认证时，一个区域中所有的路由器在该区域下的认证模式和口令必须一致;OSPF 链路认证相比于区域认证更加灵活，可专门针对某个邻居设置单独的认证模式和密码。如果同时配置了接口认证和区域认证时，优先使用接口认证建立OSPF 邻居。
每种认证方式又分为简单验证模式、MD5验证模式和 Key chain 验证模式。简单验证模式在数据传递过程中，认证密钥和密钥ID都是明文传输，很容易被截获:MD5验证模式下的密钥是经过MD5加密传输，相比于简单验证模式更为安全;Key chain验证模式可以同时配置多个密钥，不同密钥可单独设置生效周期等。

4、思考
OSPF认证如果采用MD5 验证模式，有没有办法可以获取其密钥内容?
解答：没有办法，因为采用MD5验证方式后，OSPF传递的是一个128位的密文的摘要。这样比明文传送口令更加安全。

OSPF被动接口配置

OSPF 被动接口也称抑制接口，成为被动接口后，将不会接收和发送OSPF 报文如果要使 OSPF路由信息不被某一网络中的路由器获得且使本地路由器不接收网络中其他路由器发布的路由更新信息，即已运行在OSPF协议进程中的接口不与本链路上其余路由器建立邻居关系时，可通过配置被动接口来禁止此接口接收和发送OSPI报文。

问题：在本实验中，通过配置被动接口可以禁止OSPF收发Hello报文，是否还有其他办法也能实现？
解答：接口网络类型改成NBMA也不会主动发送hello包，另外只能通过安全设备进行数据包过滤实现了。
