Eric, I've been re-reading this passage, and thinking about it, and I am not so sure that the intent was to completely divorce area authentication ( under the ospf process ) from interface authentication. Consider that you can configure area authentication ( under the ospf process ) on one side, along with the approrpiate interface configuration, and all that the other side needs is interface configuration. And it works! Somehow that does not seem like an intended consequence. Is that your understanding of the intent? The passage quoted above "appears" to me to be saying that the intent is to allow the interface specific configuration to be different than the general area configuration. Maybe a concession to mixed vendor environments? I just found it fascinating that one now has a number of options, and that one can now introduce authentication without necessarily enforcing it on all interfaces. Anyone know any of the IOS progammer managers? I'm really curious about the thought behind this. > > CL - Thanks for the heads up the other day about the OSPF Parkhurst > book...Pulled it from my bookshelf and wiped off the dust just yesterday and > I'm currently on page105 going through it with my highlighter.

RE: REdistrubution - Two way [7:63827]
IF it is the service provider/telco I am thinking of then yes there are a few issues with their rip-ibgp redistribution. A major customer of ours uses them for their framed-mpls connectivity. One of the known issues are with rip advertised routes being 'lost' in their mpls cloud and pe (redistribution) routers not advertising defaults out. Although, it could be that their ios version, since it is 'tailor made' for their vpn/mpls/vrf setup. *who knows* they are in the process of upgrading this to 'normal' code actually. Although, if we are talking about the same telco, when I had talks with their tier3 guys, it was proposed to accomodate customer networks to use link state protos in the future through their mpls cloud. *shrugs* Apologies if I seem to have missed the plot in my discussion with the topic, but I have come in half way through this thread :-) Fact of the matter is, there is no valid reason to have rip running between customer edge to telco pe - especially across 150+ satellite sites on a /16.

[7:65115] I just took the CCDP Recertification exam, exam number 640-529. I got an 878. You need 768 to pass. There were 115 questions and I had extra time. You get 2 hours. The test wasn't too bad. The copyright on the test is 2000. That will give you a clue regarding what's on there. The test was clearly broken up into 4 sections: remote access, CID, routing, and switching. Remote access was pretty easy because I studied for it. CID still had the ancient technologies and bizarre wording we have come to know and love. :-) Routing was the hardest for me, not because it included any routing protocols recently added to other tests, but because the questions were tough. But at least they were well written. I'll have to study OSPF summarization better for next time (CCNP recert coming up too.) The switching questions ranged from outrageously easy to tough. I was shocked at how badly written they were. The author of the switching test doesn't seem to be a native English speaker. There were missing articles, and verbs that didn't agree with the subject, and other clues that the writer wasn't a native English speaker. That's OK, but doesn't Cisco have editors? Also some of the right (I think!) answers had the logic backwards. Perhaps if you're thinking in another language and translating, that could happen. But I survived and am still a proud CCDP!

Just configure HyperTermianl properties to use TCP/IP Winsock. When this first came up I assumed people meant Telnet over Ethernet, but HyperTermianl lets you Telnet over the serial port, I soon discovered. Of course, you could also use exernal modems. The fact that you can dial into the Internet is more proof that you can run TCP/IP over the PC's serial port. Regarding the USB network adaptors that connect a PC to Ethernet: I don't know if they use PPP or SLIP or something else accross the USB port. That's a good quesiton.

ccbootcamp vs certzone labs [7:59815]
Hi All, hope noone had to work too long during the xmas break.. Was hoping to get a non-biased opinion(s) on the ccbootcamp labs and certificationzone labs.. was thinking of getting 1 of the 2.. but not both! :-) I know the ccbootcamp labs are quite "beefy" from what I remember a few years ago, but I'm not sure about the certficationzone labs.

mc3810 tftp bug? [7:60001]
Hi All, Has anyone experienced the following: mc3810 bootstrap 12.0(6r)T4 IOS: mc3810-a2jk8sv5-mz.122-13.T.bin and mc3810-a2jk8sv5-mz.122-13.bin memory: 64mb dram/16mb flash I upgraded the bootrom to utilise 64mb dram / 16mb flash. I am able to load the above ios code when in rommon mode. However, once I am running the above 12.2 code and want to reload another ios code (any or any file for that matter) into flash, the tftp download stops (.) after approx 10 udp packets have been successful (!) and the tftp server (cisco) application then aborts. Subsequently, the tftp transfer timesout. The only way now to load ios is to get back into rommon mode and copy over the ios image into flash (since the previous flash contents had to be erased to accomodate the "to be" installed ios). Can anyone else replicate this?

I don't recommend the Cisco Press book on the subject at all. As for mcast, I would strongly recommend the CP book "Developing IP Multicast Networks, Volume I" by Beau Williamson. I always think that good instructors make better authors than about anyone else. Mr. Williamson apparently teaches the internal Cisco course on the subject and is some kind of mcast advisor to the CTO or something along those lines. Reading the book is somewhat like sitting a course. The style is very conversational. The reason that I think instructors make great authors is that they have a pretty good idea of the problems you are going to have as a learner. They've seen the dumb looks and fielded all of the silly questions. This author clearly takes advantage of his background teaching the subject.

Neither of those. It's an address that you make up, (making sure it fits any addressing schemes you might have and isn't a duplicate of anything else, of course). It is the address that the router uses for the real destination MAC address when an end station sends a TEST frame to a host or other destination. In other words, it is the address that the router is mapping the real destination MAC address to. See here: http://www.cisco.com/warp/public/cc/pd/ibsw/ibdlsw/prodlit/dls12_rg.htm This entire feature is a conglomeration of awful technologies that would have maybe worked despite their complexity, if we hadn't upgraded from hubs to swithces. The problem with switches is that they remember where MAC addresses are and get confused by redundant routers in a DLSw+ environment. To avoid problems, the redundant routers map the destination address to unique addresses that you configure. Unless you really need this feature (or have to learn it for CCIE for some bizarre reason), I would definitely stay clear of it! :-) Priscilla > > Thanks so much for your help in advance, > > Best Regards, > H.

RE: IOS process scheduler algorithm [7:60206]
Nope - From step 3&4 in the book. There are no counters for critical and high priority queues either. The 'failsafe' for servicing the medium priority is when all the processes in the critical and high ready queues have been executed or when a medium priority instance is found when servicing the low priority queue (intervleave) - all the medium processes will be executed. The scheduler will not service the low priority queue within 15 times of skipping the low queue - and even then, if the scheduler is executing low priority instances it will still service a medium (or critical or high) process if one is found in the ready queue. hth, Mark. -Original Message- From: Marc Thach Xuan Ky [mailto:[EMAIL PROTECTED]] Sent: Friday, January 03, 2003 6:21 AM To: [EMAIL PROTECTED] Subject: IOS process scheduler algorithm [7:60206] Hi all, I am reading Cisco Press "Inside Cisco IOS Software Architecture" and have some outstanding questions about the scheduler, maybe somebody can help me. The text describes how the low priority queue is only skipped 15 times before it is serviced even when there are processes queuing at higher priorities. Does this count up to 15 include the times that both medium and low priority queues are skipped? There seems to be no similar counter for the medium queue, am I correct then in assuming that the only failsafe servicing of the medium priority queue is acheived via the "interleaving" occuring during failsafe servicing of the low priority queue, which would imply the answer to the first question? rgds Marc Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=60292&t=60206 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: PVST vs PVST+ [7:60419]
One of the best switch reference investments you will make is if you buy a copy of cisco lan switching by clark and hamilton. pvst allows multiple instances of SPT within a switched network, ie. 1 STP per vlan. dot1Q allowed only 1 instance of SPT. and of course they have different framing definitions. so we have an interoperability problem here with different vendors, codes releases, etc. (cant remember when pvst+ was introduced to the catalysts). PVST+ allows the 2 different implementations to interoperate (tunnelling pvst frames over pvst+ [i think if memory serves me correct - but its 2am and im too tired]). by doing this you can have eg. isl and dot1Q trunks within the same switched topology. there have since been forward developments with dot1Q, called dot1s (is it called dot1S yet?) which is like an "upgrade" to dot1Q. and now you have MISTP, RSTP, dot1w, etc, etc.. its all hard to keep up :-) but yes, go buy yourself a copy of the mentioned book. hth, Mark. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, January 06, 2003 5:30 AM To: [EMAIL PROTECTED] Subject: PVST vs PVST+ [7:60419] Anyone know what the differences are between the two?

RE: set cam permanent HELP! [7:60448]
not too sure if i agree with assigning it to the native vlan. i would
have been more incline to set it on the vlan it belongs. when you do a
show cam dyn|perm|static|system the vlanid is one of the attributes
shown - like a unique vlan:mac key pair (although mac addresses do not
have to be unique).
setting the perm entry to the native vlan would mean to me that mac is
only vis on that vlan. hence i would say set the perm entry to the vlan
the destination it is on. since a trunk is a trunk is a trunk. i would
have applied the same reasoning to an accessport.
if the mac needs to have vis across more than 1 vlan, i would add it to
each vlan required.
hth,
Mark.

hey miss P
if you do a show trunk it should show you it`s native vlan that is
the
one you are after ...
"from CCO"
The following example shows how to add a unicast entry to the table for
module 2, port 9, and how to add a permanent multicast entry to the
table
for module 1, port 1, and module 2, ports 1, 3, and 8 through 12:
Console> (enable) set cam static 00-00-0c-a0-03-fa 2/9
Static unicast entry added to CAM table.
Console> (enable) set cam permanent 01-40-0b-a0-03-fa 1/1,2/1,2/3,2/8-12
Permanent multicast entry added to CAM table.
Console> (enable)
i got the above from
http://cco-rtp-1.cisco.com/en/US/products/hw/switches/ps679
/products_command_reference_chapter09186a008007f2dc.html#13648
watch the wrap
from memory if you specify the native vlan and ONE port in the trunk
that
SHOULD include all ports of the trunk with the set cam commandI just
can`t be 100 %

disappearing default rip update [7:60937]
Hi All, Has anyone experience something similar to - the rip default not being shown in the route table and the rip database that is being sent by the upstream router? (Upstream router being a tier 2 provider). I have other routers hanging off the provider edge router that are receiving the default route. Been working on this for a few hours now with the lvl3 guys but we are both stumped. Both of us agreed to log a call with cisco. But just wondering if anyone else has seen this happen before? It's a weird one.. most likely code specific. No bugs showing for my customer's affected router.. ios version being used by the provider is ios specific to their vpn network. Cheers, Mark.

RX port buffers on cat4000's [7:61248]
Hi All, Just wondering if anyone has figures for the size of rx buffers for cat 4000 ports? Had a issue today where a port was connected to a pix 535 manually set at half/100 (yep you read right), the switch port was at auto/auto. The rate of In-Lost (rx buffer filling up) errors was on average 5 per minute (among all the other errors of course). I have seen In-Lost and delay-exceeds rise up for mis-settings to servers, but the pix connection was showing some pretty fast counter stats Hard to find these small details sometimes in doco.. maybe anyone here from cisco can advise? the mod on the 4006 is a ws-x4424-gb-rj45 (hw 1.5) with a supII (hw 3.2, gsp 7.1(2.0), nmp 7.1(2)) Cheers, M Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=61248&t=61248 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: RX port buffers on cat4000's [7:61248]
yes, alot of traffic is flowing through :-) and no wasn't related to any kind of attack. The 18mpps or 48mpps is more to do with the switch fabric, not related to the tx rx buffer(s) that are allocated per port. the issue was immediately resolved when i hard coded port settings. just wanted to have an idea of the size of buffering allocated on these ports (hardware specific of course). cheers, mark. -Original Message- From: Erick B.

Reason: Excessive input rate of traffic. * Delay Exceed - This is an indication of the number of frames discarded because of excessive delay in the switching process. Reason/Cause: Severe problem with the switch. Open a case with the Cisco TAC I'm guessing the PIX connection has lots of traffic (probably constant). maybe some sort of attack was going on at this time. Might be a combination of devices attached to that blade. There is no buffer adjustments I know of. Also the sup2 on 4006 does 18 Mpps , whereas a sup3/sup4 can do 48 Mpps. --- "Vicuna, Mark" wrote: > Hi All, > > Just wondering if anyone has figures for the size of > rx buffers for cat 4000 > ports?

OK, its a directed broadcast and router 2 looks up its routing table and forwards it out using the default route. Router 1 receives the packet. I believe the packet is forwarded out to all 192.1.1.x/26 subnets, right? Will Router 1 forward the packet back to Router 2? I hope not 2a. Another way of looking at it is router 1 thinks that it is a broadcast only for subnet 195.1.1.192 and forwards it out only to router 5. Hmmm I'm definitely confused 3. Router 5 receives the packet from router 1. How will it interpret the packet? I'm guessing that the router sees it as a directed broadcast and send it out via the default route. Is it normal that routers forward a packet out from an interface that it received on? As in its received on e0 and forwarded out e0 as well 4. Once router 1 receives the packet from router 5, will it forward the packet out to all 192.1.1.x/26 subnets again or just to router 5. The article did not detail this part and just specified that it will bounce between routers 1 and 5. It also says that routers 2 thru 4 see the 'broadcast' only once. The way I see it , if all subnets receive the broadcast then routers 2 thru 4 should receive the packets as many times as router 5. I would appreciate all the help I can get.

RE: NSSA and related design questions [7:50608]
In relation to your last paragraph, once you add the line redistribute, that router is classed as an asbr.. so the answer is no. HTH, Mark -Original Message- From: bergenpeak [mailto:[EMAIL PROTECTED]] Sent: Sunday, 4 August 2002 07:28 To: [EMAIL PROTECTED] Subject: NSSA and related design questions [7:50608] I'd like to setup a group of routers to be in an OSPF sub-area. The sub-area will connect to the backbone via one or two ABRs. All other routers in the sub-area will be ASBRs. The ABRs will not be ASBRs. >From a design perspective, I want to put these routers into a sub-area so that I can limit the amount of routing information they need to be aware of. Further, I'd like to limit what information the backbone routers see regarding these ASBRs. Stub and Totally Stubby areas are not an option since the sub- areas contains ASBRs. Configuring the sub-area as an NSSA would help limit the number of routes in the sub-area (via the ABR nssa no-summary command) as the sub-area will have just a default, intra-area, and type 7 routes from the redist process. This is good. When the ABR gets the Type 7 LSAs from the ASBRs, it will translate them into type 5s and flood them throughout the backbone. While it appears that the backbone routers don't see the ASBRs (via type 4 LSAs from the ABR), I'd like to determine if it's possible to configure the ABR to take the type 7s and include these routes instead in the ABR's type 3 LSA? This would prevent the backbone routers from seeing the type 5s. Is this possible? Or, is it possible to perform redist from RIP into OSPF, but to configure this router to put the routes learned via RIP into it's type 1 LSA (ie do a redist but prevent the router from being an ASBR) Thanks for any info.

RE: OT - ISDN viability - WAS: Re: VPDN - ISDN problem [7:53983]
Where I work ISDN is primarily used for DDR since it is the most cost effective soln in Aust - especially if you have a large number of sites to cover as Jenny pointed out. With that in mind, the way of thinking being 'we only want to pay for what we use'. There's no point in having an fr circuit as backup for each remote/branch site. Of course with our main core trunk links into the telco cloud we wouldn't consider ISDN for backup. The majority of issues regarding ISDN I have had experience over here are with provider's equipement (we have subscription to every major telco in aust. and only one telco [no names mentioned] seems to give us ongoing grief with their dated equipment - lucent att - framed route issues with ldap), and of course dialer watch :) The current configuration we have would fail bringing up the isdn circuit sporadically on a watched subnet. Resolution? changed dialer watch group to any other number BUT 1. Go figure. In regards to manual intervention.. i hope not :-)I have worked for the 2 major telco's in Aust and there's no manual intervention happening there in context of servicing their customers.

We use ISDN to automatically failover. With over 350 remote sites, it's not uncommon to have a main link to an office fail somewhere. With automatic failover, our users often don't even know something's failed. Manual intervention? You've got to be kidding. To tweak and tune if necessary, sure, but to initiate failover - no way. Been there, done that, bad idea in our network. Anyway, in Australia at least, it's still the most cost-effective failover for a network like ours (lots of sites, geographically dispersed). It has some annoyances, sure - but it's still definitely an option for me.

I want to make sure I have the right cable before I start chasing other possibilities. Is this in fact the right cable? I have searched the archives and looked at several CCO links without a clear answer (maybe I'm just not smart enough to understand what I'm reading :-)).

Hi Mwalie, How long? Depends on how long it takes for you to know the objectives I guess. Unfortunately I work so I dont have the luxury to be reading and playing around on my lab 15hrs a day =) I used MPLS and VPN Architecture book, CCO, RFC's. There is a Volume II of the book, but I have not had the time to buy it. I am sure some of the information will be useful too for general knowledge in the exam. Looking at the reviews of this book, I will get this sometime in the near future. I bought the sybex CCIP MPLS book, but found that the information was too generalised and lacking in detail in some areas. You will need to be familiar with BGP, OSPF, RIPv2 as well. Hands on is very useful as well. Yes I have done QOS (very similiar to DQOS too if you're smart) =) HTH, Mark. -Original Message- From: Mwalie W [mailto:[EMAIL PROTECTED] Sent: Tuesday, 29 July 2003 4:00 PM To: [EMAIL PROTECTED] Subject: What materials??

hi Chuck, That's the thing, the other exams were the usual 750-ish (give or take a few) with between 55-60 q's. The MPLS exam was 66q's in 75 min. In retrospect, 60 q's for the 75min for me is reasonable for specialty exams with a >750 Finally passed MPLS with 925. > > Comparing to the other core exams for CCIP, this exam was by far the most > intense. Any reason(s) why Cisco has this exam rated at 867 to pass? don't know about this one in particular, but I am beginning to suspect that Cisco is starting to look at higher passing scores with fewer questions being asked, particularly for the specialty tests. The wireless cert test I recently passed had a passing score of 790 and only 50 questions. I'm assuming you've taken the BGP and the QoS exams. Were those higher passing scores and relatively few questions as well? In your estimation, how many questions is reasonable for a specialty exam? > > > > Rgds, > Mark.
