Hello,

I have the following Problem with the topology below. If the connection between as1_r1 and as1_r6 or as1_r3 and as1_r7 flaps one time, all routers gets a high CPU load and the route 10.1.16.0/21 (the summary is configured on as1_r6 and as1_r7 on the serials) is in eigrp active state all time, because every router queries for this route....

One solution is to shut down one serial on as1_r{1,2,3} or to configure as1_r6 or as1_r7 as a stub router, but I think there should be another solution.

If needed, I could post the configurations...

Thanks in Advance
Viets

When will the interactive hands on lab be available for sims 5 and 6?

Hi All,

My employer in his infinite wisdom has decided that he is going to sell Cisco equipment and has a requirement for 2 staff to become CCNA certified.
He has booked 2 of us on the CCNA boot camp which is spread over 2 weeks INCD1 and ICND2.

I have approx 5 weeks before the ICND 1 course.

My question to you guys is how can i best prepare myself for these 2 courses??( I have very basic networking skills - i come form an IP telephony background)

Thanks in advance for you help

Jas

Hi,

Finished the exam today with 7 mins to spare. Time is fairly tight in this exam though I think.

Had the following sims:

Redistribution of ISIS into EIGRP and vice versa (Lab #4)
OSPF summarisation (Lab #3)
EIGRP summarisation (Lab #6)

Had both simlets QID:T1 & QID:T3. Got quite a lot on IPv6 and Multicast.

Also had one question about NAT-PT that I didn't see on How2Pass. There's an exhibit showing an IPv6 host sending traffic using an IPv6 destination address to an IPv4 host behind a NAT-PT router. It asks you to choose from 4 options how the traffic gets to the host. I think I answered that the router selects where to send the traffic. I can't remember the other options unfortunately.

The answer states:

"A rendezvous point must be configured in order for the interface to operate in sparse mode."

Surely though if this is the case, the following answer is also valid and there are 2 potential answers for this question?

"If a rendezvous point is configured, the interface cannot operate in dense mode."

I passed my CCNA today and I could NOT have done it without the help of How2pass!  Best $40 I ever spent! 

Good Luck to everyone on their certification journey! 

Just wondering if the answer should be "Switch4, port fa0/11"?

hello,

after reading and learning with how2pass plus some practical hometests,  i passed yesterday my CCNA test with 916 points !
I think theres a bug in the cisco test software (pearson/vue) ... i had to configure basic router config an during the exam I couldn?t type
any letter, if i want to write "config" the browser showed me "onfig" :-( I couldn?t finish the question and had to go to the next !
Did anybody have same proble?

... i ?ve passed, so maybe i shouldn?t care ...  ;D

greetz j?rsch

Thanks to how2pass

40 questions

How2pass helped me remember 4 years worth of study and I got half my recertification.
