Stub areas

jacklim — Wed, 22 May 2013 06:00:54 GMT

Hi, I noticed "stub area and the 6 major LSA types" are not covered in the 7th edition study guide which I'm using for my ccna preparation. However, I also noticed stub area configuration and totally stub are included in the CCNA Virtual Lab, Titanium Edition 3.0 Labs. As the preparation is taking longer than I have expected, I would deeply appreciate if someone can confirm if can skip these and stick to single area OSPF.

In the same vein, how can I determine if I can safely skip other topics that may be found in the CCNA Virtual Lab, Titanium Edition 3.0 Labs but not in the study guide?

Thanks!

Chapter 6 Network Protocol Memorization

Ltat42a — Wed, 22 May 2013 02:29:26 GMT

I have an Excel Spreadsheet that has those and a bunch of other topics for Net+ & CCENT. It comes with all the study information and tests for each.

Study the material, then print out the test sheets. It's designed to scramble the test questions so you don't get into a habit of memorizing topics in order.
Simply hold down the delete key for a couple of seconds, then print!

Let me know if you'd like to use it.

eigrp auto summarization question

Fuzz — Tue, 21 May 2013 13:16:37 GMT

For some reason my reply didn't get posted? Try again!

If R3 does the summary, it adds a static route 10.0.0.0 to null0 in its own routing table. Then it advertises 10.0.0.0 to its neighbours. R4 then sees the summary and adds it to its own routing table, pointing 10.0.0.0 to R3's IP address.

If R2 is also summarising, it will add its own null0 next hop for all summarised routes - it hasn't learned these from R3.

Cool - this way you are being proactive and building a solid base of knowledge going into the new CCNA.

CCNA Data Center Certification

however, I think R/S and Data Center will be equal when it comes to jobs, and you dont' want a job where you just know data center and no R/S.

Just to be clear, the new CCENT will provide a strong foundation in R/S, and after completing the new CCENT I should then pursue the CCNA Data Center?

Area BACKBONE(0) (Inactive)

I can ping Corp's s0/1 interface, which is in the same subnet as R2's active s0/1 interface. I cannot ping Corp's other two active interfaces. Configs below.

I'm using three real 2610XM routers, each running IOS 12.4.

I get no output from debug ip ospf on R2, but I get plenty on Corp and R1.

Starting to wonder if there is something wrong with the IOS installation on R2. Can't find an explanation as to why it's not becoming neighbors with Corp. EIGRP and RIPv1 and 2 worked fine on all three.

Icmp vs snmp?

Fuzz — Fri, 17 May 2013 12:46:16 GMT

ICMP and SNMP are very different.

http://www.lammle.com/discussion/arc...php/t-457.html

ARP/RARP and DHCP/DNS are also very different. ARP/RARP is used for mapping layer 2 to layer 3, DNS is used to map host names to IP addresses.

To fully explain the differences on a forum post would take a long time to be honest, so better to use this: http://www.google.com

From OSPF to BGP

Fuzz — Tue, 14 May 2013 12:01:47 GMT

OSPF by default uses AD of 110, so it has no bearing on this anyway, although I do believe AD is the cause. If you change the AD of OSPF to <20, it should stop the eBGP routes from taking precedence. Other ways to stop it would be to filter out the local routes from updates from PE2.

Where I was going with the 'how long does it take' thing is OSPF should set the routes almost instantly - it's BGP that will take time. Then when you issue a BGP clear, it forces BGP to grab an update.

Exam Track

jgraham95 — Tue, 14 May 2013 09:23:48 GMT

Looking for some advice on what track to track.

I understand the new Cisco exams are now available to sit, but I've been studying currently for the 640-802. Im looking to progress through my CCNA Security and CCNP Security eventually but I'm not entirely sure which exam's I should pursure.

Am i better off starting with the new 100-101 ICND1 then going straight onto 640-554 IINS to achieve my CCNA Security or should I continue revising and sit the 640-822 ICND1, them the 640-816 ICND2 to achieve my CCNA, from there taking the 640-554 IINS to get my CCNA Security, or can I do my 640-822 ICND1 then go straight onto the 640-554 IINS and achieve the CCNA Security?

Im rather confused still upon how the new Cisco qualifications tie in with the old. :confused:

Thanks in advance to responses

Rip routing problem

Fuzz — Mon, 13 May 2013 11:19:51 GMT

The no auto-summary command will only 'fix' a network if you use different classes of networks throughout. If all of your networks are 172.16.x.0/24, then all routes will work, even with RIPv1.

jacklim — Thu, 09 May 2013 13:02:33 GMT

Thanks. Saw your reply and quickly turn on my pc to run the Virtual Lab simulator to try the command you have suggested. But before doing so, I checked and found the previous issue is no longer there. I guess rebooting the pc and/or re-running the Virtual Lab managed to do the trick.

Anyway, appreciate your advice and glad to learn of this clear ip route command from you. I'm sure it'll come in handy for me in future.

Written Lab 8 error

Fuzz — Thu, 09 May 2013 12:29:34 GMT

BPDU filter, if used on it's own, will stop sending and receiving BPDUs on that port.

If it is set globally, any port that has PortFast enabled will also have BPDU filter enabled, and stop sending BPDUs. If that port then receives a BPDU, it will come out of PortFast mode and transition through the STP states as normal.

So if BPDU filter is enabled globally on the switch, configuring PortFast will stop BPDUs from being sent out of that port.
