I am lucky to pass the CCIE LAB exam and want to share some of my experience with you.
TS1:
Q1: The mac addresses bound to the three devices of PC101, SW2, and R8 are different. The rollover of the excuse is changed according to one change.
Q2: Here R17 has got the correct IP address, just add PPP ipcp route default, clear the routing table, the phenomenon is out.
Q3: Here on the R1 show IP os dat sum +48 network segment, you can see that the routing mask from R5 is thirty, the change can be, the phenomenon is out.
Q4: The phenomenon map given in this exam is not the same as the usual practice, but the solution is the same, through the eigrp configuration of showR13
You can see that there is a distribution list, and deny dropped the 145.14 network segment, delete it, and then the show phenomenon found that the FD is wrong, so the metric weight 0 1 1 1 1 1 was added to all four devices.
Q5: This question is a bit strange, I want to say the wrong point, the wrong point is still conventional: R22 lacks next-hop-self;
R21 hangs the route-map LP matching prefix listless 194.1.1.0/24 network segment, added;
R5 above did a summary of 123 and 134 network segments, delete it.
Weird point: I got the hand for this question. The first thing is to show the phenomenon first. The requirements of the examination room are the same as those we usually practice.
The phenomenon of the first show to 8.8.8.8 and 194.1.1.1 is straight out. I thought it was right, I went to the problem of 123 and 134.
When I solved the two summaries and then went back and tested again, the strange things appeared. The first two were unreasonable. I checked the neighbors and they were all normal.
But a trace went to the 38 and 42 points, and then lost the package, nowhere, then I thought it would be 26 problems, I want to finish the back,
Go back and do it again, but when I do MPLS VPN, because the following PC wants to access the public network, then 3, 4 does not establish the 124,125 BGP route with 7,8, I will make up,
The previous 8.8.8.8 and 194 network segments can be traced immediately. I think the problem behind this should not affect the front. I didn't figure it out, but I didn't care about it.
Q6: I don't know the question of ipv6. I don't know where the wrong point is. I just look at the configuration of 22 and 25 and find that the neighbors also.
DIAG2+:
This is nothing to say, back documents on the line, grab the package that I did not screen out, I went directly to 227 to see, and sure enough, there are old FE said FE80:: 666 this, I chose. Note that the options for the second question are much more than usual. Just look at the options carefully.
H3:
Prelude:
1, H3 at the beginning is a picture divided into two layers, the list is very clear, every switch has to go with it, including the bundle interface, I also did not see the interface below there is no access because I usually match vlan Will be matched
2, SW300 and 301 do have the command of no span, complete it.
text:
I generally seldom look at the demand and have the order of my own brush, but this is a bad habit. I still have to look at it. The previous battle report is actually very detailed. I will simply talk about it.
65003 ospf, no pit, press solution
65004 ospf, no pit, according to the solution,
65001 bgp, no pit, press solution
Ebgp for all sites: no pits and there are a lot of pre-matches, but some are incomplete, you have to check it yourself, and each one is complete.
DMVPN: A bit pit, the pre-shared key is not the same, I changed it according to R14, hang IPsec, roll at the same time, it will rise.
MPLS VPN core: All PE routers here do not have RD values. I have blinded my eyes and I have not seen where to write RD. Then I will knock according to the usual pre-matching.
L2L IPsec: I didn't get up this problem. I knocked it according to the solution. The stream of interest on R24 was reversed, and it was static. It was also determined to be redistributed, but it was pinged. I tried to tumble the interface and delete it. Re-matching, restarting the R71, it's useless. After the R71 restarted, it has been brushing a quick command, and then it didn't respond like a crash. I thought about it, it was finished, and I almost called the examiner.
Then I waited for a while and it was fine, but it still didn't work. After more than half an hour, I gave up.
Multicast: Multicast is very stable. I went up and tried to find out if it was lo1 or E0/2. Who knows that I didn't find one, I brushed it according to the solution of SPOTO, and it appeared again and again.
Section 4-5 is nothing to say, just go down and do it.
Measurement phenomenon and inspection: be sure to check!
Phenomenon: This phenomenon map except for L2L IPsec did not come out, the other ones are consistent, that is, when user4 visits the public network, I am taking 15 is not 14, I think that the thoughts on the solution are not important, I am not Got it.
The experience of going to the exam: What impressed me the most is the dry weather in Beijing. I took the train on the 14th. For an hour, my lips were cracked. In the two days I stayed in Beijing, I almost drank seven or eight bottles of mineral water or resisted. Live in this ghost weather, feel the moisture of my bod.
Every minute is drained, and children in the south can't afford it. I decided to the hotel, just across the examination room diagonally, crossing the road is still very convenient, that is, I have not found a nearby meal. Then the exam started to sleep at 8:30 on the evening of the first day.
I woke up at 9:30, couldn't sleep anymore, then fell asleep at 12 o'clock, woke up at 5:30 in the morning, got up and packed up and washed it, went to the wandering daddy and told me that I could have breakfast. Yonghe soy milk, then I followed the Baidu map and ran
Close to one kilometer, I still couldn't find the magical soy milk shop. I only saw a 711. I was too lazy to find it. I solved it here. I have to say that Beijing's buns are really delicious. After the exam was finished in the afternoon, I felt that people were very emptiness and stunned for ten minutes at the entrance of Yintai.
I don't know where to go, but I still think about going back. I went to the subway. I handed in the paper at three o'clock. I just received the mail from the subway station at four o'clock. This time it was very fast. It was better. I finally didn't let me run. some interesting thing: At first, I thought about IE. I came from the beginning of the 17th year. At that time, I was fooled into a spicy chicken institution. The lectures were also spicy chickens. When I asked for an exam, I was always unstable. Many people in my class have given up on this institution and gave up, then I am a colleague.
I bought the version of SPOTO, and I was very recommendable when I started the version of Sibo. Because the theory is not solid, sometimes it takes two or three days to finish an H1 or various Since tr, I often ask old thanks to some mental retardation problems, and most of the time later
Study your own problems. On August 18th, I was really annoyed. I wanted to give this broken thing quickly. I went to sign up for a test, and then I was miserable. I was depressed for a long time and relaxed for a long time. Really The review should be after the New Year, sprinting
For more than a month, (but my sprint is just a knock in the day, of course, going out to play at night and weekend). I still want to thank Lao Chen for his help. Qingming’s days and nights have changed my simulation test day and night, and I have worked hard. There are too many nonsenses today, I hope everyone can get the number as soon as possible.
