本人公司网管，接触思科设备十年了，平时思科交换的经验多，路由的经验少。
' L; V! `+ i3 X* R. t这次np先是9月份过了tt,上周五29号过了路由851分。6 r. `+ j8 ]8 c6 M' X1 D
周末要陪老婆孩子，工作日每天学习大约一两小时，刚开始准备一边看题库一边看论坛里的路由的视频，后来发现看视频太慢，会影响整体进度可能导致明年考不完交换，就专攻题库了。看的是精简版，年过不惑精力不济，晚上有时看着看着睡过去，有的题目记不住，只能去了解理论知识加深记忆。最后选择题自测每次正确率90%以上，每道实验题都做了四五遍。因为要留出时间给交换，所以计划必须11月完成路由，考前一周看了一遍完整版题库，没怎么记住，怀着忐忑不安的心情走进考场，幸好过了。
8 @& P5 W2 g6 E+ ]# j8 r" R |考题共55道，3道实验题，OSPF，EIGRP Case，OSPF IPv6，最后这道题题目要求把所有不正确的配置都改正，改正越多得分越多，我按题库答案新加了R2-R3的virtual-link, 去掉了R3-R4的virtual-link，R1上有了R4环回(FEC0:4:4)的路由，满足了题目要求，但是R4上没有R1的路由，R2R3上都有R1的路由，不知道什么原因，可能扣分了。

Explanation
3 c" V# Y1 s0 ?- v+ }" a* X. aThe Management Plane Protection (MPP) feature in Cisco IOS software provides the capability to restrict the interfaces on which network management packets are allowed to enter a device. The MPP feature allows a network operator to designate one or more router interfaces as management interfaces. Device management traffic is permitted to enter a device only through these management interfaces. After MPP is enabled, no interfaces except designated management interfaces will accept network management traffic destined to the device./ m3 K! \3 A, Q2 }5 V
In the command management-interface interface allow protocols we can configure these protocols (to allow on the designated management interface):

A. R1 redistributes network 10.1.80.0/24 into EIGRP without changing the mask B. R1 changes the mask to /32 and then redistributes network 10.1.80.0/24 into EIGRP as a classful network C. R1 changes the mask to /32 and then redistributes network 10.1.80.0/24 into EIGRP as a classless network D. R1 fails to redistribute network 10.1.80.0/24 into EIGRP! \" T+ A8 q& Z5 K9 R8 W
