| Hey guys,
Just wanted to let you know that I wrote 640-607 and failed with 796. I'm pretty disapointed since I studied the book inside out. I kinda got screwed on one of the sim. I had a sim which had 3 routers and asked me to troubleshoot the connectivity. I thought it was the router rip which was missing some entries therefore I configured all 3 of them and after I did that, I was able to go in the midde router and ping every interfaces on the other routers but the routers on the side, could only ping the local interfaces and the first serial interface of the neighbor router. I spent 25 minutes on that question and couldn't figure it out. Anyone have any idea what could of went wrong there? I'm not too sure what other questions I got wrong.
This was my score:
Bridging & Switching 67%
OSI Model & Layered Communication 67%
Routed protocal 83%
Routing protocols 78%
WAN services 67%
Network Management 67%
LAN Technologie 67%
Cicso & Networking Basics 50%
I had a lot of subnet questions which I think got them all right since I'm pretty good that that. The reason why my score is low on everything is because of that SIM. Please help. Well now I have to study 640-801. Anyone know any good sites for material since I don't really want to buy another book since I bought the 607 one.
Thanks. Good luck for everyone! | |

| Did you correctly enter the IP addresses and subnet mask for each interface. Did you correctly enter the Network statements after you issued the Router Rip command? When you configured the three routers, did you remember to specify no shutdown on the interfaces and save your configuration? I am not sure what commands are available on the simulation questions, but you can verify your routing tables by using sh ip route. This will show you what is in the routing table and how it was learned. Also on the serial interfaces, did you specify a clock rate?
The exam syllabus is different enough that you may want to invest in a new set of books. Cisco press has a two book set available for 640-801 that you can get from Amazon for about $42. You can also locate information on the additional course requirements at the Cisco website. The passing score is still about 85 percent for 640-801. The simulation questions do not touch on all areas of scoring. | |

| During the exam, I did do the Show Ip route command and all the routes were there. I did the show startup-config and the router rip command was there will all the route possibles. It was a class C network so I had to put like 5 different numbers. I also checked if all the interfaces were up which they were. The clock rate for the serial where fine. I have no clue what went wrong. Thanks for the advice on the books. I had the Sybex book and then I went to the book store and looked at the Cisco Press books and they seem to have more details therefore I might invest in one. I'm in Canada so the books are a little bit more expensive here. Probably $89 Canadian. I'm not sure what went wrong with that Lab. If the middle router was able to ping all the other interfaces, that means the clock rate and the interfaces were up on the other routers so I'm not too sure.
Now I have to look what kind of difference there is between 640 and 801.  | |

| Make sure you get the new books for 640-801. The old ICND books won't cover all of the topics on the new exam. | |

| Thanks.
I just bought a new book from Cisco press which covers the ICND 640-811 exam. I don't think I have to do too much studying for 640-821 since that didn't change much. I think I'm going to write one exam though. With the cisco press book, it came with the Boson Software which I found really good. Hopefully all of this will help me pass it the next time. | |

| One more thing I forgot to ask. Does the ping command work on the exam? Because maybe that was the problem as to why I didn't think it worked and the question might of been right. | |
| justindu 2003-10-27, 11:47 am |
| Yes ping works in the sims. | |

| I had the exact same problem as you did with that sim in the exam. I did everything I know for RIP ect and still it did not work. | |

| I'm not too sure what went wrong. That's why I was asking if ping works since I was able to ping everything with the middle router but when it came to ping with the two routers on the side, you can only ping internal interfaces and the neighbor serial interface but couldn't go through the middle router to ping the interfaces on the other side. I thought rip was the only thing I had to configure since all the interface were up and the clock rate was set, Ip address were assign correctly. After configuring rip though the middle router was the only one with a full routing table. When I did Show IP route on the other ones they only had 3 entries or something. Not too sure what happened. | |

| I am not sure but did you check the startup-config for some ACL lists ? for example some that deny traffic from first router (one side) to the second, that could be the reason why you were able to ping from router in the middle, am i wrong ??

| Also Rip v1 doesnt transfer subnet informatino in its updates. So, it can't utilize VLSM or CIDR.
I think the 607 didnt have this information though. It's just good to know that in case you see it on the new exam. | |
| joel316 2003-10-30, 10:26 pm |
| So if your saying Rip 1 doesn't transfer the information, you have the make sure that under Router RIP command you have the following. Let say router one has ethernet 192.16.5.1 and serial is 192.168.8.1 and Router two has the same thing ethernet 192.168.11.1 and serial 192.168.8.2 and the other serial 192.168.13.1 and final router 192.168.13.2 for serial and the ethernet is 192.168.15.1. So the router rip command would have the following on the first router
Router rip
network 192.168.5.0
network 192.168.8.0
network 192.168.11.0
network 192.168.13.0
network 192.168.13.0
Am I right. Because this is kinda like the lab but when I checked the startup-config, there was only one entry on each router under Router rip. Would I of been right if I modified the running-config with those entries?? |
