Re: BGP load balancing
ebgp multihop has nothing to do with load balancing traffic to and from the Internet, but it has everything to do with load balancing the the bgp connection and update itself. If you have two parallel connections to the same router at your ISP and you configure two neighbor statements to the ebgp peer router on the connected networks you'll transfer the bgp table twice, once on each link. Possibly many megs of wasted bandwidth. If you configure one neighbor statement sourced from a loopback in your router going to a loopback interface on the ISP router, you'll have to have ebgp-multihop configured too, otherwise it won't work. Then turn off route caching and the bgp table will be sent only once and will be load balanced accross the two T1's. If one T1 dies, your still in business Rodgers Moore ""Chuck Larrieu"" <[EMAIL PROTECTED]> wrote in message 00d401c04eb9$b6c5b360$[EMAIL PROTECTED]">news:00d401c04eb9$b6c5b360$[EMAIL PROTECTED]... > EBGP multihop has nothing to do with load balancing. > > As for using BGP to control incoming traffic from your ISP, I would say > there is no simple answer here.

Re: Rumor Alert - Lab Changes - WAS: Flame bait.

My Cisco contacts include all the Cisco employees that comprise the weekly CCIE Design study group that I attend, (they invited me, a non-Cisco employee to join their study group!) Also includes the managers that fund the study group; facility, lunches, courses, speakers, and a fully equipped Design lab. They do tell us that the CCIE Design certification is to some extent a work in progress but they remind us that they all were in the beginning and they all constantly undergo revision.

Re: % Connection refused by remote host
I use a terminal server daily to do configuration on our bank of lab routers. I typically see that error when I try to connect to a router when a previous session is still active. If you're connecting to the console port only one connection can be "alive" at one time. Unlike multiple telnet sessions. So check to see if that line is active and clear it if need be.

Re: BGP load balancing
Andy, ebgp-multihop simply allows you to specify the TTL of the ip packet containing bgp updates, etc. This is useful if you have multiple parallel paths configured for per-packet load sharing. To control traffic entering your autonomous sytem, you can use route-maps to prepend your autnomous system number one or more times for a specific prefix towards a specific neighbor, making that path less preferable. Also, you may have the option of setting specific communities on prefixes outbound towards your providers that will accomplish various things. You'll need to check with your providers to determine if that is a possibility though. --phil On Wed, 15 Nov 2000, Andy wrote: Hi all, I want to know that does command ebgp-multihop provide load balancing over ATM for a router, also how can I configure ebgp to control incoming traffic from my ISP Regards Andy _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: Single area with large number networks.
OK, I now think the right answer is B and D also. Jenny, Pamela, and Howard have convinced me. As Howard said, Answer C, "frequent adjacencies table recalculation" is even more BS than Answer D, "excessive link-state entries in the link-state table." There's no such thing as an adjacency table. There is a neighbor table, but it doesn't get recalculated unless a directly-connected DR or BDR goes down, which doesn't happen that often. In Answer D, they probably just meant link-state database, which is another term for "topology database," as Pamela pointed out. And Jenny and others pointed out that as the number of networks in an area increases, the number of LSAs increases, but the number of adjacencies each router has doesn't necessarily increase. So we should be looking for a right answer that talks about scaling links, not adjacencies. So D is right. B is also marginally right. A is definitely wrong. C is probably wrong too. Anyway, it's probably silly to be arguing over which answer is more wrong! &;-) I think the only thing we can conclude is that you would not have been able to find the answer by going to Cisco's search engine and this discussion was very worthwhile.

PIX vs Nokia Firewall
Hi Currently we are planning to move away from software firewall (Checkpoint running on solaris) to hardware based firewall. Since Nokia is also running checkpoint, migration should be simple. However I have heard a lot of good comment about PIX. I have few questions to ask: 1) Does Nokia (400 series) has a hard disk ? I understand Nokia FW runs on BSD variant. How about PIX ? Does PIX has a hard disk? (Harddisk failure is the reason for migrating to hardware based fw) 2) Nokia vs PIX, which is more powerful ? Eg. Nokia 440 vs PIX 525 3) Your comment on Nokia and PIX.

PIX-How's that 'U' work?
The PIX 515UR is a real nice addition. I've got 3k workstations behind 24 class C's. The "U")nrestricted license is for thousands of connections. But, this site has a Proxy server. This means that there will only be a handful of internal stations really hitting the PIX/net. Of course, there is mail, a web server, and one or two other systems needing external access. Is that Unrestricted license really necessary? What might I loose down the road if I decide on the restricted license?

BCMSN passed with 934, details inside
I took the BCMSN this afternoon and exited the testing center with a very surprising 934. Background: I have a couple of years time in grade with cat 19xx/28xx, about the same more recently with 29xx/35xx, and I once worked for three months on an incredibly psychotic Cat 5500 with 800 MACs in the cam and one subnet(!). I've also done one Cat 5500 + NFFC + RSM layer 3 deploy to an ISP with 40k worth of public IPs being routed through the switch. Study gear: I had two Cat 3524s running enterprise attached to a Cisco 2621 running 802.1Q VLANs in production at work. I had a loaner Cat 5000 with a Sup 1 and a ws-x5213 for the last few weeks of my studies. There was an idle 7206 in a remote facility that I used to brush up on mls rp commands. I did some multicast work with my 25xx collection at home. Study Materials: Didn't refer to Caslow once(!). The Cisco Press BCMSN book (only a few errors) and the official Cisco Press LAN switching were all I used. The LAN switching reference does an excellent job of covering some items that the BCMSN gives what I felt was a lightweight treatment. The boson.com pretests were *excellent* - my only gripe is that what is in boson's stuff is *way* harder than the real thing - I was getting mid 60% on the boson stuff and I thought I'd squeak by the exam ... the 934 was a huge surprise. What to watch for on the exam: I think the BCMSN question base is *very* broad. I've talked to folks that had to examine network sniffer traces and so forth and I saw none of that. The possible broadness being mentioned the details are ... Pound VTP operations into your head and do it twice for that stuff about version numbers. Use the same amount of effort on spanning tree and VLAN configuration issues. MLS is there but if you *understand* the BCMSN chapter on it and then read the Cisco Press LAN Switching you'll be fine. I am amazed at how little there was on multicast - knowing how to convert an IP address to a MAC address covered 50% of what I saw. This makes me think the exam question base is broad because I've talked to others who got a lot of multicast questions. I really got flogged on Cisco product line knowledge. I worked for an equipment dealership and I've troubleshot/tested/sold/refurbed everything Catalyst from 1912s to 65xx series include all of the layer 3 modules and I was streeetccchheddd by what the test wanted to know. I can eyeball a box full of Cat 5500/6500 cards and tell you part numbers and specs on them - I rarely need to refer to the fact Cisco product guide any more - and I was really reaching on some of this stuff. If my experience is represenative you should call 800-553-NETS and order DOC-CISCOCATALOG= and memorize the 55/6500 layer three stuff before approaching the exam. Well, thats all the wisdom I have to offer at the moment ... I am going to go pounce on CIT and see if I can be a CCNP by this time Friday ..

Subject: RE: BCMSN Hex- IP to MAC
I actually have another method that might work better for some of you. After
having played with hex/bin numbers for almost 15 years, there are some
patterns and tricks that comes alive.
Designing sprites on my Commodore 64 and Amiga 2000 and new characters on my
PC, has filled my head with some of those reappearing numbers, so if you can
memorize the value of the sixteen combinations for the first four left bits
the right four bits should be pretty easy to figure out.
First of all, if you have to bits set that has a bit between them, it will
give a "nice" number.
For example 1010 is 128+32=160, 0101 is 64+16=80, and a combination
of both is 240. That already gives you three combinations to
memorize.
Then there's the situations where only one bit out of the left four is set :
128, 64, 32 and 16. They should be fairly easy to remember too, and now
you're almost halfway there.
When you look at all sixteen combinations:
: 0 00
0001 : 16 10
0010 : 32 20
0011 : 48 30
0100 : 64 40
0101 : 80 50
0110 : 96 60
0111 : 112 70
1000 : 128 80
1001 : 144 90
1010 : 160 A0
1011 : 176 B0
1100 : 192 C0
1101 : 208 D0
1110 : 224 E0
: 240 F0
You can again see that it's simply the 16 scale, and if you remember those
16 numbers, it should be easy to subtract it from the original number which
gives you the right four bits.
Furthermore, if you write the above table down on your plastic board before
you start your test, you should be able to convert it in seconds.
Example 178:
1) You look in the table and see that 176 which is B0 is the closest equal
or less than 178.
2) 178 minus 176 is 2 so now you have your result B2.

Yeah but you would still have to divide the 8 bit decimal up in two 4 bit
decimals before you can use your memorization, unless you want to memorize
all 256 combinations in decimal, hex and binary - and maybe octal's too :-)

Cool trick. Hadn't seen that one before. As I look at it, it actually does
the same thing as the method I posted, but skips the binary conversion step
(splitting the one octet into two quartets is equivalent to dividing by 16).

you can also go from decimal to hex by dividing by 16 example given 235
235 / 16 = 14 with a remainder of 11
14 in hex is E

RE: Single area with large number networks.
My vote goes to D (and B, but I don't think that's under dispute). OK, so 'excessive' is subjective, but then so is 'large'. The question's not asking WHEN the problems will occur, or even claiming that problems will occur in all circumstances, just asking what POSSIBLE problems there are. My reasoning is that as the number of networks increases, the number of LSAs increases, but the number of adjacencies each router has doesn't necessarily increase (by much). The question implies single OSPF area, so summarisation doesn't come into the picture. Given a finite amount of memory, CPU etc on routers, a 'large' number of networks will cause a 'large' number of LSAs, which have to be refreshed every 30 minutes regardless of network changes, which causes traffic, CPU usage, etc - and potential problems. Especially if you interpret 'large' as 'large enough to cause problems'.

I believe we all agree that B - frequent routing recalculation - is "correct" I believe we all agree that A - more reachable errors - is BS Of the two remaining choices, which is least wrong? My reasoning was that C - frequent adjacency table recalculation - is irrelevant because an OSPF router forms adjacencies only with directly connected neighbors, and not necessarily with every router in the area. The result of the "show IP OSPF neighbor" command, even in very large networks, would be relatively small. That leaves D as being the other "correct" answer. Yeah, I see your point, Priscilla. On the other hand, all of us have seen a wide variety of terminology for the same think. Link state database, link state table, OSPF table, OSPF database, and so on. It is not unreasonable to conclude that the test writer has his or her own jargon for what we call the OSPF database. If D is wrong, then the choice is C, and that's problematic.

I agree it wouldn't be excessive. Within a LAN, the DR mechanism keeps adjancies and LSA propagation from getting excessive. Between areas, the number of LSAs would depend on summarization. So without more information on the network topology, addressing, and configuration, we couldn't even say when LSAs would be a problem. Besides, as I look more closely at the answer, I see that it says, "excessive link-state entries in the link-state table." What's a link-state table?

RE: T-1 Vs DS-1
Hmmm, I would prefer the question to read: (Q) At what speed does a T-1 run over DS-1? But don't take my word for it...Here is an EXCELLENT T1/DS1 tutorial. Bookmark this one...because there are very few T1 explainations that actually talk about the F-bit & S-bit. He (Bob W.) does an excellent job breaking down the DS1 Signal levels (Pulse/LBO/etc), etc http://www.dcbnet.com/notes/9611t1.html The designation "DS" in Figure 3 refers to "Digital Signals" and describes the physical layer. The designation "T" refers to the type of carrier that is being used. Often these are used interchangeably but that technically is not correct. ... When someone says they are running T1, they may be saying several different things: They may mean that they have a network that is passing data at 1.544 Mbps; they may mean that they have a network that conforms to the T1 electrical interface specification (DSX-1), or that they have a network that passes data that conforms to one of the several framing formats (D4, ESF, etc.). More likely than not, they mean all three but their concentration may be on only one of these items. The confusion in the user community is a result of the inter- changeability of words and the confusing requirements for connection to the AT&T system. ahhh the memories...just glad you didn't ask about E&M signalling ;-) HTH, TroyC an old telco junkie -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Tuesday, November 14, 2000 1:02 PM To: [EMAIL PROTECTED] Subject: T-1 Vs DS-1 Pick the right answer here Q.)

Re: OSPF Load Balance/Metric
Looking at this from another angle... Perhaps the interviewer was trying to ask a follow-up question, along the lines of 'what if there is congestion? What would you do to deal with it?' (traffic shaping, prioritisation and fiddling with OSPF costs on the links spring to mind as possible solutions that could be mentioned, depending on the situation of course).

I couldn't find any >documentation showing that OSPF takes congestion as a metric. He is REALLY wrong in trying to consider congestion as part of a routing algorithm. While (E)IGRP can consider it, EIGRP does so only for IGRP compatibility. IGRP's use of load is one of those things that sounded good at the time of development, but has not been useful in practice. There are emerging protocols that consider load/utilization, but in a manner quite different from the way IGRP does. IGRP only considered utilization on directly connected links, which can lead both to route oscillation and very bad end-to-end routing. One newer approach (e.g., OSPF-TE, ISIS-TE) is to do explicit bandwidth reservation before the routing protocol runs. When the routing computation runs, costs are derived from available bandwidth, not link bandwidth. Bandwidth reservation is either static or over a substantial time period (e.g., RSVP). Another approach (OSPF-OMP, ISIS-OMP) does consider utilization, but averaged over a significant period, and as part of a link state algorithm that does consider end-to-end. > _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Any X.25 pros out there?
This question may not prove to be so difficult. I am in a discussion (a nice way to say an arguement) and I am so hardheaded I will not let down. The big question is whether in an X.25 configuration when there is a translate statement set does it indicate that when a packet coming into that router destined for X.121 address it will be translated to IP's in this pool. or Does the translate statement say any packets destined for this IP pool will be translated to this X.121. or are we both painfully wrong? or are there no people working with this old decrepid technology to worry about it? >>>Brian _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Perplexing: DHCP fails from Ethernet segment to Token Ring segment
Hello all, I've configured a Cisco 2513 router to do full bridging between its Ethernet port and its Token Ring port. I'm using plain transparent bridging (bridge 'x' protocol ieee). The network is broken down into two segments: one switched 10/100 Ethernet segment, and one Token Ring segment. The Cisco 2513 sits in between the two. Currently, the majority of the workstations and servers (including an NT Server running DHCP services) are on the Token Ring side. Initially, I had problems bridging the two segments together because of MAC-address bitswapping issues (Token Ring uses an inverted MAC address, Ethernet doesn't). These issues have been resolved by using the 'bridge bitswap-layer3-addresses' command. However, when Windows 9x/Windows NT workstations on the Ethernet side attempt to obtain a DHCP address through the bridge (to the NT Server on the Token Ring network), they fail to obtain IP addresses. Statically assigning an IP address to these machines works fine! I'm thinking that, perhaps somewhere in the DHCP REQ and ACK packets, the Ethernet MAC addresses are not being handled properly on the NT Server DHCP server. Could the IP address assignments be sent back to an invalid MAC address? Any help would be appreciated!

I personally feel that a substitution of database for table is acceptable. I think we would all agree, that a large number of prefix's would lead to a proportionally large table/database of link states. Here is an excerpt from 2328 "The collected link state advertisements of all routers and networks forms the protocol's link state database." However, if D is wrong, which of the other 2 are right? I would tend to think that D is the least wrong of the three remaining choices. Overall, I think this is another example of technical lack of precision leading to unnecessary ambiguity.

Re: switch port IP address
I'm not sure what is downstream of your switch, what types of devices, but I'm pretty damn sure that there is no command on a catalyst switch (a layer two device) which will tell you the IP addresses of the devices connected to it. The switch not only doesn't know, it doesn't care. Presumably you have a router which is upstream of the switch and all devices hanging off of the switch have the ip address of the router interface (which connects to the switch) as their default gateway. Only the router will know the IP addresses. Depending on your needs and urgency the only way to really deal with this would be to write a script which takes the cam table from the switch (which will list mac addresses and ports to which they connect) and the arp table from the router (which will map mac addresses to IP addresses) and match them up so you end up with a list of IP associated with MAC associated with switch port. I am pretty much positive the switch doesn't know the ip addreses. As you mentioned cdp neighbor detail will tell you the address, but that will only work for cisco devices running cdp. Doesn't help you at all for devices from other manufacturers.

RE: Single area with large number networks.
But if the "right" answer consists of two choices... I believe we all agree that B - frequent routing recalculation - is "correct" I believe we all agree that A - more reachable errors - is BS Of the two remaining choices, which is least wrong? My reasoning was that C - frequent adjacency table recalculation - is irrelevant because an OSPF router forms adjacencies only with directly connected neighbors, and not necessarily with every router in the area. The result of the "show IP OSPF neighbor" command, even in very large networks, would be relatively small. That leaves D as being the other "correct" answer. Yeah, I see your point, Priscilla. On the other hand, all of us have seen a wide variety of terminology for the same think. Link state database, link state table, OSPF table, OSPF database, and so on. It is not unreasonable to conclude that the test writer has his or her own jargon for what we call the OSPF database. If D is wrong, then the choice is C, and that's problematic.

I agree it wouldn't be excessive. Within a LAN, the DR mechanism keeps adjancies and LSA propagation from getting excessive. Between areas, the number of LSAs would depend on summarization.

Hmm, Priscilla, I have to disagree with you here--RFC 2328 refers not to a "topology database," but to a "link-state database." I find many of the terms commonly used to describe OSPF are not precise, and it's important for those new to internetworking to be aware of this. "Topology database" and "link-state database" seem to be used interchangeably by some very knowledgeable folks, and I don't really think one is more correct than the other--after all, they both refer to a data structure that describes the topology of the OSPF internetwork for that area. The Cisco course materials tend to call it a "topology database," but I wouldn't be the one to suggest that makes the RFC incorrect. Here's another example: RFC 2328 refers to a "neighbor data structure," but it is almost always called an "adjacencies database," "neigbor table," or in more recent Cisco course materials, "neighborship database" when people write about it. All those terms mean the same thing--a place in the router's memory where it stores information about its neighbors. Radia Perlman has a nice rant on the topic of imprecise terminology in the 2nd edition of "Interconnections." Highly recommended, for those who haven't already seen it. ;-) Pamela _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: BCMSN Hex- IP to MAC
I actually have another method that might work better for some of you. After
having played with hex/bin numbers for almost 15 years, there are some
patterns and tricks that comes alive.
Designing sprites on my Commodore 64 and Amiga 2000 and new characters on my
PC, has filled my head with some of those reappearing numbers, so if you can
memorize the value of the sixteen combinations for the first four left bits
the right four bits should be pretty easy to figure out.
First of all, if you have to bits set that has a bit between them, it will
give a "nice" number.
For example 1010 is 128+32=160, 0101 is 64+16=80, and a combination
of both is 240. That already gives you three combinations to
memorize.
Then there's the situations where only one bit out of the left four is set :
128, 64, 32 and 16. They should be fairly easy to remember too, and now
you're almost halfway there.
When you look at all sixteen combinations:
: 0 00
0001 : 16 10
0010 : 32 20
0011 : 48 30
0100 : 64 40
0101 : 80 50
0110 : 96 60
0111 : 112 70
1000 : 128 80
1001 : 144 90
1010 : 160 A0
1011 : 176 B0
1100 : 192 C0
1101 : 208 D0
1110 : 224 E0
: 240 F0
You can again see that it's simply the 16 scale, and if you remember those
16 numbers, it should be easy to subtract it from the original number which
gives you the right four bits.
Furthermore, if you write the above table down on your plastic board before
you start your test, you should be able to convert it in seconds.
Example 178:
1) You look in the table and see that 176 which is B0 is the closest equal
or less than 178.
2) 178 minus 176 is 2 so now you have your result B2.

Yeah but you would still have to divide the 8 bit decimal up in two 4 bit
decimals before you can use your memorization, unless you want to memorize

Cool trick. Hadn't seen that one before. As I look at it, it actually does
the same thing as the method I posted, but skips the binary conversion step
(splitting the one octet into two quartets is equivalent to dividing by 16).

you can also go from decimal to hex by dividing by 16 example given 235
235 / 16 = 14 with a remainder of 11
14 in hex is E
11 in hex is B
answer EB
Another example 149
168/16 = 10 with a remainder of 8
10 in hex is A
8 in hex is 8
answer A8 hex
To convert hex to decimal is just as easy take the left most hex digit and
multiply it by 16 then add the right digit
EB in hex
E * 16
E=14
14*16 = 224
B=11
224 + 11 = 235

RE: Single area with large number networks.
Telling someone to use the Cisco search engine for a question like this is not helpful. It was kind of funny, but also a bit cruel, and definitely a waste of bandwidth. Answer A "more reachable errors" is clearly wrong since it's nonsense. I think answer D is wrong also because an OSPF router doesn't really have a link-state database. It has a topology database. (I'm not an OSPF guru, but when trying to pass a test I look for cases where the test-writer garbled the terminology to make a wrong answer.) It's not really an easy question because the acceptable number of routers in an OSPF area depends on many things: How stable is the network? If the network is really stable, then OSPF doesn't do much. Routers send hellos to each other and that's about all that happens. How busy are the routers already? Are they approaching a CPU utilization that could cause problems if the shortest path first (Dijkstra) algorithm has to be run often because of network instabilities? How much memory does the router have to hold the topology database and other data structures? See the groupstudy archives for some good discussions by the Chucks on OSPF scalability.

I have only done the first two tests so far and got more that 90% on each my first try. can I expect to pass CCNA based on these results or are the Boson exams easier. any input appreciated Thanks Pieter Jordaan -Original Message- From: Vazquez, Gervasio [mailto:[EMAIL PROTECTED]] Sent: Thursday, November 09, 2000 10:00 PM To: '[EMAIL PROTECTED]' Subject: _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

I am starting work on my CCNP and will be purchasing lab equipment. I would like to start a studygroup in Madison Wisconsin and also provide people access to my lab. My plan would be something like this; Once a week have a group study where we can talk about topics and work out some senarios in the lab. The rest of the week you can purchase lab time where it's all hands on (you can tear down and rebuild the routers). You can do what you want during your lab times or run some scenarios. I hope to have a lab consisting of 3-4 ethernet and 2 token ring routers, a couple of switches (hopefully a Cat5K?!) and a PIX box. If all goes well, I would add ATM and Voice equipment. I would also set up the lab for internet users to telnet/term serv in for when users are not there working (mainly during normal work hours and late night). I'm not looking to make money, just re-coup some money for the lab investment and get myself and some fellow Madisonians certified.

Also if anyone has suggestions for the lab, please let me know. I would also like to offer free lab time to those people who send me scenarios, but that will be a little later down the road. Thanks.

RE: Labs for BCMSN (CCNP)
Usually I am in "voyeur" mode on the list, but I think I will start voicing my opinions on selected items...If you look at the objectives for the Switching test you will see that there may be product specific questions. It is all dependant on the questions you get "from the pool". As I journey onwards to the golden router, and take tests along the way that will challenge both my mental and physical capabilities ( ha ha ), I realize one thing. I cannot know ALL of every subject. My weakness when it came to the switching test was multicast. Talking with my peer who took the test the week prior, he said he saw maybe 2 questions on multicast the rest were the typical product specific questions, ISL, VLAN, trunking, etc. So when I went in, I was pretty confident in my chances...but alas I pulled probably all of those da** multicast questions. Luckily my strengths kept me afloat. What does this have to do with your question? Hmmm...let's see. In my opinion you should know ALL that you can know, and realize your weaknesses, and pray to the router gods that you do not get hammered on that subject...by the way I did see a few product specific questions. Oh yeah, and alsoknowing a little design theory cannot hurt you...!! I enjoyed the BCMSN book...cannot stand the BCRAN...!! And limited access to switches should not prevent you from regurgitating product specific questions...(i.e. backplane, no. of line cards, forwarding rate, max MAC addresses, etc.) -Original Message- From: Mari Misato [mailto:[EMAIL PROTECTED]] Sent: Tuesday, November 14, 2000 11:09 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: Labs for BCMSN (CCNP) I just finished reading the same book.

RE: Single area with large number networks.
>"Ibrahim" <[EMAIL PROTECTED]> May I make some suggestions here? Learning to use the cisco website indeed is important, and indeed is not the only way. In this particular case, I don't think you will find the answer there. Why? Because there have been recent discussions on this list about OSPF sizing and on OSPF failure recovery. These discussions did require looking at the RFCs, and also some expert opinion that largely isn't written down. So, I'd say in this case, if there was an appropriate autoreply at all, it would have been "check the archives." My suggestion here would be to write why you think b is a correct answer, and what your thoughts are about each of the alternatives. But I do have some specific technical comments; see below. >if you said refer to www.cisco.com, why everybody still need this >mailing-list ? why there are many questions in this group ?

As to the specific question, I think it's poorly worded. I would say, however, there are three correct answers. a) If I assume that more networks and routers are present, then logically more can fail, requiring recomputation. There isn't any simple answer to sizing this, since it depends on the reliability of the networks and the CPU power of the routers in the area. b) If, by the routing table, they mean the area route calculation by OSPF, yes. What I think of the main routing table, however, is that which is shown with sho ip route, which is not the same as the transient OSPF topology table. NOT c): There is no such thing as an adjacency table. There is a neighbor table, which doesn't get recalculated unless a directly connected DR or BDR goes down. d) Well, yes. The more networks, the more LS entries. On the other hand, this isn't usually a major limitation. CPU power is more likely to be a resource limit. I wonder if the author of the question might have been thinking of the OSPF Database Overflow feature, which Cisco doesn't implement since iBGP handles that problem better. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Labs for BCMSN (CCNP)
I just finished reading the same book. I find it covers quite a lot of design topics which I think they shouldn't be in this course since it's a CCNP exam, not CCDP. I also have very limited access to Cisco switches. Does anyone know whether this exam is product specific? I think there are also errors in this book but I can't seem to find the errata sheet. Could anyone give the URL?

I don't see the bureaucracy in the response. I meant simply to make the point that any certification merely opens doors to interview processes. Remuneration is so varied is not worth discussion.

RE: Single area with large number networks.
Given the context and the choices, I would have to pick B and D as well. The routing table recalculation isn't really a great answer either. Suppose your links never go down, and once that last router is turned on and all the SPF's have been done. This sucker would remain pretty quiet. But... given that links do go down, routers go off line and back on, etc, yes - routing table changes. So B D is to me the answer of last resort, one of those things Cisco loves in their tests. Let's look at the other answers: More reachable errors. Huh? What is a "reachable" error? Frequent adjacencies table updates - now this one has the ring of truth about it... Excessive link state entries in the link state database...this rings true also So of the two that ring true, which one is more correct? I would choose the excessive link state entries because in my reading from various resources I have seen expressed many times router capacity, memory requirements, processing power. This last one falls into that category. I don't ever recall reading about adjacency table updates, but I won't say it doesn't happen. Show ip ospf neighbor does sho adjacencies. but you are adjacent to only a small number of routers, no matter what the size of the network. So, A and D Test taking 101 - answering Cisco questions the Cisco way Chuck -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Cthulu, CCIE Candidate Sent: Tuesday, November 14, 2000 5:33 AM To: [EMAIL PROTECTED] Subject:Re: Single area with large number networks. IMHO, B is the best answer as link failures in the area will cause recalculations. D is a possible answer; however, "excessive" is a subjective word: OSPF will generate the number of LSAs necessary to build its tables and the picture of the network: it will not go beyond the number needed to do so. On the other hand, as a human, I may find a large number of LSAs "excessive".

Rumor Alert - Lab Changes - WAS: Flame bait.
Before you all get hot thinking about CCIE specialties and the money you can make, you may want to facto in a couple of RUMORS about the CCIE track I heard recently. Rumor #1 - The CCIE Design certification is being dropped. Why? Because no one can figure what it is supposed to be or do, and the lab itself is a crock. Rumor #2 - The CCIE ISP/Dial lab is being revamped completely. It is turning into DSL / Cable Modem etc. Don't know about the ISP side of things - BGP, IS-IS, peering, etc. Rumor #3 - The CCIE Security will involve configuring Cisco security products on both Unix and NT boxes and doing VPN tunnels end to end, meaning for the first time a candidate would be responsible for end user equipment in the lab. Them changes is coming. Remember - these are RUMORS, and may or may not be true. Always check the Cisco web site for the facts.

Re: [configure router thru aux port]
The auxiliary port is used for remote access to the router through an asynchronous modem. You have to assign an ip address to the asynchronous interface mapped to the auxiliary port on a router. The auxiliary password is used to set a password for the aux. port . This port is used to connect a modem to a router for remote console connections. The commands are router# config t router(config)#line aux 0 router(config-line)#login router(config-line)#password azhar router(config-line)^z It is important to connect the modem to the router before configuring the modem to verify that communication between them is established. If the cabling is incorrect, the rest of the process will fail. For a complete router-modem connection, consult the following URL http://www.ieng.com/warp/public/76/9.html Regards Azhar Soomro "ALI SHEERAZ" <[EMAIL PROTECTED]> wrote: hello friends, I need to configure router (2501) thru aux port...I need its configuration..can anybdy help me..
