We apologize for the short notice and plan to provide more notice in the future. If you're planning to attend please RSVP to so we can get a good head count. BTW, more info on RTPCiscoUsers can be found at Yahoo Group. I'm a member of the group and will answer what questions I can.

Re: Route Summarization [7:1794]
OK, I think I got it. /15 doesn't make sense if I want to pick up just a 10.2.0.0 network because it would also pick up a 10.3.0.0 network. /16 will work if its the intent to summarize at 10.2.0.0, however that over summarizes if its not our intent to pick up 10.2.0.0 Therefore the three addresses: 10.2.1.0/24 10.2.2.0/24 10.2.3.0/24 can only be summarized as: 10.2.1.0/24 10.2.2.0/23 Thanks to all for your responses, they helped loads (especially if I got it right this time) Steve Howard C. Berkowitz wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I want to summarize three addresses within an OSPF area: 10.2.1.0/24 10.2.2.0/24 10.2.3.0/24 Converting to binary, I see the 15th bit is the highest order bit the three addresses have in common. From that I see the summary address is 10.2.0.0. What I don't understand is why the subnet mask is 16bits. To me it looks like it should be 15. Thanks, Steve There's a widespread and unfortunate belief that summarization is OK if it includes a list of addresses, even if it picks up addresses not included in the list. True, you can probably get away with that in many enterprise situations, but it can be catastrophic in the Internet. As I interpret the problem, the minimum number of addresses that can be created from your example are: 10.2.1.0/24 10.2.2.0/23 You can't do the /22, because it would pick up 10.2.0.0/24, which isn't part of the list. /15 or /16 make no sense. Converting the third octet to binary: 10.2.0.0/2400 00 10.2.1.0/2400 01 10.2.2.0/2400 10 10.2.3.0/2400 11 ^^ ^^ 111222 22 789012 34 FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=1864t=1794 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Route Summarization [7:1794]
Thanks Chuck, I think the number of bits in the mask equals the number of highest order bits the addresses have in common. By highest order bit, does that mean a bit set to 1? As for the mask being 16, that's what the approved solution for a virtual lab says. It is possible the solution is wrong. At any rate, it has me confused. Steve Chuck Larrieu wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I would think your mask would be more like /22 than /15 Do you really want to summarize at the /15 boundary? 10.0.0.0/15 might be it.

Re: Tax Credits
The only tax relief I know of is on your Schedule A. There of course, these expenses are only deductible after they exceed 2% of your adjusted gross income then only the amount above the 2% threshold. If you own your own business, I would expect you could expense or depreciate the assets. HTH Steve ""CiScO"" [EMAIL PROTECTED] wrote in message 96qbu3$8cb$[EMAIL PROTECTED]">news:96qbu3$8cb$[EMAIL PROTECTED]...

Re: CIT/Support 2.0 Exam and Boson Tests
Title: CIT/Support 2.0 Exam and Boson Tests I haven't taken the exam yet, but have purchased both tests 1 2. If I were only to purchase one, it'd definitely be test 2. The questions are more challenging, and more importantly, the answers include references both from the Cisco Press CIT book and from the Cisco web site. Test 1 doesn't include references in the answers. Robert is the author of test 2. I was also extremely impressed with his FRS exam -- there was no comparison between his and the other.

Re: CIT/Support 2.0 Exam and Boson Tests
Title: CIT/Support 2.0 Exam and Boson Tests After rereading my post, I think I might have given the impression Test 1 isn't of value. I am finding questions there that aren't in Test 2 -- in short, I think its a worthwhile test. I still believe Test 2 is superior because of better questions and in references. If I had it to do over again, I'd still purchase Test 1. I don't see me purchasing Test 3 (I don't know anything about it, but don't want to spend another $30 and feel the two tests will be sufficient).

Re: Question for DR/BDR in OSPF
Doug, I see you're using one of your "lifelines" I'd go with answer B make it your final answer. Reason as stated in the ACRC book is "The only time a DR or BDR will change is if one of them goes down. If the DR goes down, the BDR takes over as the DR and a new BDR is elected. If the BDR goes down, a new BDR is elected." HTH, Steve "Doug Laing" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... This is a question for study purposes. I want to verify what I think the answer is: Let's say Router A is the Designated Router with priority of 100 and fails. Router B (Backup Designated Router) with priority of 90 becomes the DR and Router C with a priority of 80 becomes the BDR. If Router A comes back up on the network? A) An election held and Router A becomes the DR and Router B becomes the BDR.. B) No election is held until Router B goes down. Then Router A becomes the DR and Router C remains the BDR. C) No election is held until Router B goes down. Then Router C becomes the DR and Router A becomes the BDR. **NOTE: New CCNA/CCDA List has been formed.

Re: Question for DR/BDR in OSPF
Upon further review, I agree with Michael and Peter -- answer C is correct. The text I originally quoted (p 193 ACRC) so states. Steve ""Peter Abraham"" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Doug, I believe the answer is C. The order of promotion is always from BDR to DR when the DR fails. If router B fails then router C will be the DR, and router A which has just come up on the network then becomes the BDR. Peter.
