Q1:Which material is most helpful
Q2:which packets can help you find the cause
Customer just setup a IPv6 Network, with HSRPv6 on R1 & R2. After setting up, all hosts lose connection.
What would you recommend to your L1 Engineer as a Quick Fix?
CE1 key configuration
standby 1 priority 200
standby 1 preempt
ipv6 nd router-preference low
CE2 key configuration
standby 1 preempt
ipv6 nd router-preference high
I think it is a rouge device because I don't see any problems with the HSRPv6 config. PCs are configured with "ipv6 enable", "ipv6 autoconfig"
The R1 have a "ipv6 nd-preference high" and R2 have "low" if I'm not wrong.
How fast fix the problem?
¡ Shutdown the link between CE2 and PE2.
¡ Shutdown the link between CE1 and PE1.
¡ Configure CE1 with highest HSRPv6 Priority.
¡ Configure CE2 with highest HSRPv6 pirority.
¡ Configure CE2 with low HSRPv6 priority.
¡ Shutdown CE1 interface e0/0.
¡ Shutdown PE2 interface e0/0.
¡ Disable fast-switching on CE's LAN.
¡ Enable fast-switching on CE's LAN.
¡ Change HSRPv1 to HSRPv2 version

Master Wu Lin said. of the day, the forum has spread more than 60 points boson questions, no Lab 5-1: Configuring Active/Standby High Availability Lab 3-1: Configuring NAT Managing the Cisco ASA Adaptive Security Appliance Boot Process In binary transfer, the bit order of the file is saved so that the original and the copy are bit by bit. Even if the file containing the bit sequence on the destination machine is meaningless. For example, Macintosh sends the executable file to the Windows system in binary mode. On the other system, this file cannot be executed. Cisco ASA Adaptive Security Appliance Licensing Requirements The first type: broken bookThe knowledge of the Internet is very extensive. The routing and switching in CCIE is only the most basic direction, but even the so-called technology-old veterans can hardly know that it is 1%, not to mention the speed of knowledge update is very fast; In the field of Cisco, there are dozens of media, hundreds of interfaces, 20 link technologies, more than 100 switching technologies, IPv4/IPv6, routing protocols, and no less than one thousand advanced routing technologies. Such as quality of service QOS, traffic engineering, multicast applications, network management, security management, *** and defense monitoring, IP voice communication, IP storage, optical transmission, access services, etc.; at first contact with this knowledge, such as into the sea, I want to eat all through, do not have the right method, look at the book every day, and put the limited life into the infinite rush; not to mention that it is not necessarily able to learn every day, knowledge is also aging, new constantly come out. A technician will let you keep learning for 10 years, and you won't have to break the book with a solitary sword. The "breaking book" in the book-breaking style has several meanings. 1. The book is poked off. The book is used for investigation, not for viewing. 2. If the book is poked, the book is more, and the book is distracted. If there are fewer books, they will use their heart to understand; if they have eaten one piece, then they will eat another piece, and gradually, the skill will continue to grow. The problem is now that the technology is very thorough, and there is no shortage of general knowledge. The foundation is not very good, the more you look at it, the more difficult it is to return. So the first step in learning is to not read a book or read a book. I originally prepared a book that I have read in a month. I will "see" it in 2 days. Believe me, what you know after 2 days and what you know after 1 month. It's the same or even better.Second style: imaginationThis move is followed by the above move. Internet knowledge is divided into two parts, one is transmitted online, the other is running in the device; such as traffic shaping technology, the protocol is transmitted on the line, the signal is fixed, the line is not the peer device Recognition, and the algorithm, queuing, caching, and mechanism are running in the device. To master this knowledge, the things uploaded by the line can be found, and the content should be remembered. The things that run in the machine, you can't see, can't sniff, read the system source code is too inefficient, only the imagination can be cracked: 1, not a fantasy, all machines, always follow the logic It is not difficult to understand these logics for those who are qualified. 2, technology is always born to solve the problem, such as encountering a problem, you think, if you design and solve, what will happen. 3, although do not understand, just think about it; brain utilization is less than 10%, do not worry that your brain has been developed. People's potential is very big, can not be done, relying on excavation. Because I don't understand, so I think that there is no constraint. Einstein also came out like this. You think it might be better than the actual one. If you understand it later, you will laugh at the developer's use of such despicable means. 4, from the basics of the beginning, eat and sleep, walk and ride the car can think, so that others only have 10 hours a day to learn, but you have 24 hours. Can you not make rapid progress?The third type: forcedMany people learn for a while and progress slowly because they don't know how to force themselves and control themselves. What we often do is this problem, everyone is very clear. This is a layer of meaning, and there is another layer of meaning, that is, to force yourself too much, recognize the dead, this everyone ignores it? Then how to solve this move: 1, forcing yourself to read: reading can not understand, you can not see clearly, because your knowledge of the fault is broken, the basic logic is not yet available, then go to see advanced applications. I gave up in the middle, so that your efforts in front of you will not be wasted. You have to come back later. At this time, you should force yourself to read it, look at it quickly, don't understand it, and don't waste any time thinking about it. Finally, after reading it, I don't understand. But always after reading it, always know some jargon, you can swear, and you won’t feel guilty inside. 2, forcing yourself not to read books, such as you read CCNA's book, and ultimately can not reach the level of CCNA, is Paper. At this time, I just went to CCIE's experiment, knocked it according to the configuration, and finished a few sets. Looking back at CCNA's book, it is like a college student's book of primary school students, which can definitely reach the level of CCNA. 3, forcing yourself to scalp to do experiments, such as learning OSPF, 5 regional types, 7 LSAs, 5 routing modes,pass ccie lab, regional authentication, link authentication, virtual links, etc., these light reading, you remember is not strong, And I don't know the specific changes and applications, or the sentence, first go to the experiment, do not understand at first, forcing all the changes to be debugged again, the depth of understanding goes straight to the environment. 4, forcing yourself to face the problem, always do easy, do not find problems for yourself, to a certain extent it is difficult to make progress; add 1000 routing entries to their router, change parameters, restart, do redundancy, close interface. ..
