BGP Problem [7:6376]
We have a problem with BGP , We need your advice to isolate the cause and solve the problem . We have three downlinks and two upliks . We use BGP at one way for incoming traffics . So we advertise our own IPs through the three providers Interpacket , Netvision and paltel . We successfully do BGP peers with the three links . I do tests to see how the world see us . I do test from the site ( http://www.1anetworks.com/test1.htm ) . The result is that : 1- When the three links on ( BGP sessions ) Most of the world reach us through Interpacket . 2- I do individual Test for every BGP session alone . and all the three advertise our routes . 3- For example from Telehous1-UK the as-path =4 through Interpacket , as-path = 4 Through Netvision and = 6 from Paltel . 4- I prepend the routes through Interpacket so as-path =6 . the expect result must be that Telehous1-UK reach us through Netvision . But in fact the whole world still reach us through Interpacket Which means that the AS-PATH is not the factor in that issue. So What do you think the Cause . and What you advise us to do .

Weird OSPF result [7:6369]
Hi all; I have very interesting question that I want to discuss. I set up an frame-realy Hub and spoke OSPF in my lab environment ( only 1 routing protocol). r1- Hub (Cisco 2501, Enterprise Plus) r2- Spoke (Cisco 2513, Enterprise Plus) r3- Spoke (Cisco 2620, 1S, 1E, 1BRI, IP Plus) r4- Spoke (Cisco 2511 IP Plus) r5- Frame Relay Switch When I was trying to distribute defualt route into OSPF domain by the following command " default-information originate always metric 100 metric-type 1 "into R2 The expected result is that, other router in the same OSPF domain will have default route, metric 100 and type 1. But I did not have the expected result, only type 2 distribute in other router, try to adjust bandwidth, etc, . When I tried to implement the same configuration but differnet spoke (2 & 4) the results was expected. Any comment will welcome! PS. All the spokes have similiar setting, except the one implement defualt route ( 2 areas and 1 defualt route) Vincent Chong Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=6369&t=6369 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: another OT: why you UNIX guys look down on we [7:6358]
Phil, Welcome to the fold... At the risk of prolonging an off topic thread that had probably gone on too long already, let me just say, a Fortune 500 company that pays 2-3 times market value for skillsets that are in abundance will probably not occupy a spot in the Fortune 500 for long. When I estimate 2-3 times market value, I am not referring to the NT skillset either. A veteran project manager can reasonably expect to make $120-$150k/yr. There are bound to be exceptions, but I doubt highly that anyone making above that range would bother bragging to a Cisco list about it, particularly touting himself as an NT expert, where the high end of the range is probably $80-$100k/yr. Further, an hourly billing rate of $150/hr translates north of $300k/yr ($312k, to be precise). Finally, an answer to the original question, why Unix guys look down on NT guys... My personal grudge against Microsoft is multifaceted... For starters, I'm not fond of Microsoft's business practices. Their efforts to stifle innovation, to the point of destroying other companies that actually did manage true innovation, are legendary, and well documented. As a proponent of the free-market, and a firm believer that competition in the marketplace benefits the consumer, how can I possibly be pro-Microsoft? I am also not pleased about the fact that the average Windows user has absolutely no idea how these wonderful machines work, and I lump NT Administrators in with that group (Average Windows Users). The term "IT Professional" implies a certain degree of expertise, or it used to. The teeming masses of know-nothing NT system administrators have forever tainted that category of skilled labor. Compare an NT systems administrator's depth of knowledge to that of a Unix systems administrator. There is very little to compare. In addition to knowing how to maintain his boxen, the Unix guy typically knows how to program, and I don't mean Visual Basic... I mean C, C++, and countless methods of shell scripting for automation. A Unix guy knows about system security... He does not run non-essential system services, because he understands that each active process on his machine represents a possible security vulnerability. As a result, he turns those services off. Ever run a system sweep against the average NT box? My god, who knew that there were corresponding services for all of those TCP port numbers? Run the same scan against the average Unix box... Chances are, it'll be far more mundane, with maybe a dozen services in use. An NT Administrator wears a tie... A Unix sysadmin wears a T-shirt, and occasionally it may even be clean. The Unix guy knows that he is indispensable to the organization, because he is capable of performing acts of deep wizardry. The NT guy hopes to make a good impression, because he knows that kids are getting out of High School with their MCSE, and he knows damn well he can be replaced. An NT Administrator sees that his shiny new Win2K box has an OSPF service, whatever that is, and he turns it on. A Unix sysadmin knows bloody well what OSPF does, and he turns it on, so that he can redirect network traffic through his desktop machine, perform some traffic shaping, and hog all of the network bandwidth for Napster and Porn downloads (Ok, maybe that's just me, but would an NT guy have thought of a way to do that?) While I could go on endlessly, further alienating NT Admins everywhere, I choose instead to close with this one salient point... A Unix guy not only knows what a FAQ is, but he generally makes an effort to find it, and once found, he typically reads it. When the time comes, he sends an email to majordomo, with a body of "unsubscribe cisco". Can the same be said of your average NT guy? I think not...

Re: another OT: why you UNIX guys look down on we NT guys? [7:6364]
Blasphemy.. UNIX *AND* NT guy?!?!? Any self-respecting UNIX guy would not rest until everything was does with a UNIX box (from WWW/FTP/Mail server, to file serving, to routing, running SAMBA (to see hidden shares on Windoze machines), to running the whole house with X10 hehe)especially anything an NT box can do, even if it means writing your own drivers (LOL).. and anyone that's an NT guy obviously doesn't have what it takes to be a UNIX guy (that's why he's an NT guy) =) I don't think a UNIX and NT guy exists =) (please no flames. it's a joke for cryin' out loud) Unless they're living in the same place as leprechauns and unicorns.. in which case, there are no computers/networks. =) Mike W.

Well, I checked Cisco's website: http://www.cisco.com/warp/public/10/wwtraining/certprog/testing/current_exam s/640-504.html According to the above link, ATM and LANE are listed as Network Protocols covered by the exam, so I have to give you that...

elementary? [7:6359]
Forgive me if this sounds a little bit basic but this is what happens when you rush into things without understanding the fundamentals. Suppose a 24 port 100Mbit switch called A is uplinked to another 24 port 100Mb switch called B via a 1Gb connnection. Suppose hosts D through N are on switch A and hosts M through X are on Switch B. Would conversations between the hosts from Switch A to Switch B occur one at a time or are multiple conversations multiplexed over the 1Gb uplink? I'm just trying to find out if and how that 1Gb uplink is used up. Thanks in advance. I'd put TIA but I hate those little acronyms. No flames please.

RE: Help on Cisco 4000 Switch [7:6191]
Friend, eh?!? Oh the humanity... ;-} Well, you could set a static entry but why? The ARP table is designed to be dynamic so that it doesn't grow to a large size and really create additional overhead. Remember, before ARP does its broadcast search, the switch will check the ARP cache. The bad news: the ARP cache is parsed from the top down. So if the table becomes large, static entries may actually slow things down. I wouldn't get into the habit of adding static entries, but if "his" little heart desires it so badly... BTW - removing the router's entry from the ARP table will not disconnect it from the switch. All that it really does is force the switch to broadcast for the MAC address of the router if it's not in the table and that really doesn't take much time at all. If a disconnect is really happening, then you...I mean he...has other issues to contend with.

Well, I'm sure that everybody knows Cisco's corporate strategy has always been to try to figure out what's going to be hot, and then just acquire somebody. Sometimes it works (Grand Junction still being the best example), sometimes it doesn't. But I've never seen Cisco as much of a research-oriented company, at least not in the lines of Lucent, with its world-class Bell Labs, or Nortel. Rather, it is a sales/marketing driven company that also likes to play the acquisition card. So I'm sure that if and when lambda switching really gets big, Cisco will come calling, wallet in hand. The suits in Cisco must be thinking something like: "This acquisition strategy has worked pretty well so far, so why not keep doing it?" Of course, this strategy is not so easy to do when your stock price has crashed. Cisco better figure out how to get its market cap back up. Note - for would-be flamers - I am not commenting on whether Cisco's dumping of the 15900 was a smart or stupid thing. What I am saying is that doing so was perfectly in line with its corporate culture. And I'm sure we would all agree that it is extremely difficult for big companies to change their culture.

BGP community string question [7:6340]
All, When matching community string in BGP routes, it seems to be different than matching as-path, I have seen expression(new format in cisco) like 701: * to match any strings starting with 701, in as-path term, it should be written like " 701: .*" I saw the 701:* from juniper manual, did not find anything similar on CCO So if there is a "701:*[3-4]2" expression, what does it match? I guess 701:32, 701:42 are obvious, anything else does it match?

Re: Wanna Be a CCIE? Try This One [7:6076]
Hey Chuck.. I just thought of something. you only need 2
routers to have 3 OSPF Areas in your diagram you show a router "inside"
each OSPF area, however, OSPF routers (at least in my understanding and most
Cisco Press book diagrams) are either totally inside an area (all interfaces
inside a single Area, although they may connect elsewhere using other
routing protocols, we're only considering OSPF) or sit on the edge of
multiple areas (ABRs). Having said that, I would think the problem now
becomes one like this: (please excuse my ASCII drawing skills =)
| Area 0 | | Area 1 | | Area 2 |
| R1 R2 |
| ___| || |___|
The Virtual Link is now between R2 and R1. In this "new" scenario, there is
no issue about where the traffic destined for Area 1 goes (it goes to R1).
Can you further explain the scenario you speak of with 3 OSPF Areas with a
router in each Area?That sounds more like a BGP thing where a router is
"inside" an AS but can connect to routers in other ASes (via eBGP) without
being part of the other AS.

Re: Questions about vlan? [7:6329]
The use of VLANs erects barriers to contain "broadcast domains." As a result, you need an external mechanism for cross-subnet browsing for the Network Neighborhood. Most people find it useful to utilize a WINS server. When a node is configured to use WINS, it registers it's name an IP address on startup. It also uses the WINS server database for resolving the names and addresses of other nodes throughout the network. When properly configured, the WINS servers acts as a "browse master," and populates the contents of your "Network Neighborhood" icon/folder/directory. You can then use it just like you normally would. Alan - Original Message - From: "Derric" To: Sent: Tuesday, May 29, 2001 9:28 PM Subject: Questions about vlan?

Re: Strange Problem with router... [7:6293]
Hi Have you changed anything in the network of late? With the very little amount of information you have provided (about the network), my first thought is something with SNMP is polling the router at a regular time. There are several SNMP bugs in several versions of the IOS. The last time I was faced with something like this, a edge router was going brain dead (70-99% CPU) every hour on the hour. It required a reboot to get it back. I had recently added a fair amount of NAT and ACLs to the router and thought that was the problem, but it turned out that another admin working on getting Cisco Works up and running had inadvertently put Works on the production network. There was a bug in the IOS on the edge router and when Works polled it, it would hit 70-99% CPU and would have to rebooted. I upgraded the IOS and the problem went a away.

Re: Does MPLS really live up to all its hype? [7:6151]
Mike, I agree with you. cisco definitely made a fatal mistake here and leave a huge room for at least one company, Juniper. I do not know anything inside and just talking about this off the top of my head, if Juniper can recruit those optical R&D people from cisco, and developed its own lamdarouter, cisco will loose its core market forever. I have heard some big carriers are replacing their GSR with Juniper, if Juniper can use their credit and make some solid optical routers, the rest of market will be shared by Lucent, Nortel and some others, there is no place for cisco at the core.

Re: Ram in 2500 series [7:6187]
I just plugged in the Fast Page Mode, 72-pin with true parity and 60ns 16Mb of memory module. The router could not load the IOS at all. So I think the speed of the memory is different. I checked Crucial.com and found out that the memory for 2500 series is using 72-pin Fast page mode with parity. So according to my memory, the speed of the memory does matter. I just don't know what is the correct speed? Mine are 60ns and it doesn't work. Someone knows the specs for this? Thanks!

Re: Wanna Be a CCIE? Try This One [7:6076]
I would have to agree...Given that there are 2 European sites and 2 US sites, I think the overhead of BGP would be negligible, while at the same time providing a graceful solution to a sticky problem. I think you stated your point very well that, even tho the network may seem "small", the fact there are multiple sites with redundant links makes the network more complex like a "large" network, no matter how many actual routers, end PCs, etc. Using BGP (eBGP treating the 2 networks on each continent as a different BGP AS) would definitely make things simpiler to manage while giving more control using routing policies and prefix lists. CCNP BSCN Question #1: When to use BGP? (two of the possible answers) 1) When the flow of traffic entering and leaving an AS must be manipulated. 2) When the AS has multiple connections to another AS. Breaking the 2 London routers into an AS and the two US routers into an AS, it seems to me being able to maniuplate the routes between the 2 continents' ASes would be convenient and fits the purpose of BGP very nicely. But also consider: CCNP BSCN Question #2: When NOT to use BGP? (three of the possible answers) 1) Low bandwidth between ASes. 2) Lack of memory/CPU power on those routers 3) A limited understanding of BGP route filtering and selection. Kevin: What are the speed of the links between New York/London and San Jose/London? Can the routers at each site handle running BGP? Do you understand BGP and route filtering? If the links aren't too tiny, the routers can handle it, and you understand how to implement BGP route filtering, this BGP solution doesn't sound bad to me My 2 cents. Mike W. "W.

RE: Migration EIGRP-OSPF [7:5724]
Yes, We laid in OSPF over EIGRP since the administrative distance of EIGRP is 90 and OSPF is 110. We were then able to check the OSPF databases on each router to make sure that all routes are advertised correctly. The final step was to remove eigrp. This results in some downtime, but it was easier to schedule a block of downtime and cut over.

Passed CIT [7:6316]
Last friday I passed the CIT exam to complete the CCNP track. I scored a 796/699. All I can say is that I was very unprepared :) I used the Cisco Press book which was very helpful and would have been enough if I would have focused on the correct things. I also used the Bosen CIT test #1 which was not very helpful at all. The test seemed to be more of a 'technologies' test in the sense that there were a lot of questions concerning layers 1 and 2, asking how the packets were switched and about signalling and things of that nature as opposed to things like routing protocols and the higher layer information. Well I passed and learned not to ignore anything but that I instead should have just started studying the material at the depth needed to pass the written test. Im a CCNP now after only 8 months of even knowing what a router is. Working on routers at work and in my own lab has been extremely helpful. Ben, CCNP PS.

This assumes that you have telnet access to the terminal server.

1. The number after the NAT and Global commands represent the pool number. So for inside interface the nat should be 1 and the global should match. 2.

Anyone got the keystrokes/shortcuts for moving around a rack via a 2511 terminal server fluidly and effortlessly? I know about Cntrl Shift 6 x to jump off a live session and reverse telnet to another router. How do I disconnect altogether, so that I do not keep on having to clear line all the time?

Once I added the following command I saw that RIPs were going out with sap encap. Albany(config-if)#ipx network 100 encapsulation sap Albany(config-if)# We had this conversation before and I think it was generally agreed that the encapsulation command for Ethernet is useless otherwise with one other exception. The encapsulation command also comes into play with routing between VLANs. You can configure isl or dot1q or sde. But as far as simply configuring the IP encap, there doesn't seem to be a way to do this. This is a case where the documentation doesn't help because it doesn't explain the usage well enough. But from tinkering, those are the conclusions I have drawn. Regarding ARP, here is what we surmised last time: A router sends IP packets using the encapsulation that it receives them in (for a particular device). But what's the first packet it will probably receive from an IP workstation? Probably an ARP. So ARP has to be configured. By the way, configuring an 802.3 ARP causes the router to use both 802.3 and Ethernet II. It uses Ethernet II if it gets no response with 802.3.

RE: IP Address [7:5786]
A network address can never end in an odd number. Given the IP address 172.16.0.1 and a /21 subnet mask, the network number in this case would be 172.16.0.0. The next network number would be 172.16.8.0 and so forth.

Pix Firewall 515 [7:6301]
Questions on configuring the Pix Firewall 515. 1 I have an internal network that is using nat 1 on the inside interface to access the internet. My understanding of the pix is you have to nat your addresses in order for the pix to protect them. Should I use Nat 0 to protect my external or public address and if so how should I set it up. 2 I have a machine on the internal network that needs to be accessed from the outside. I have static mapped the internal address to a public address and set up a conduit for the address also. Isn't that the solution or am I forgetting something. I still can not access the unit. Please advise I am lost If you have any advice please let me know.

yup. thats going to happen when you plug that many serial links into the 3640. look at the mtu, look at your pps, and look at the 2640's forwarding capabilities. i have a cusdtomer who's 2640 freaks out the same way with 8 t-1s coming into it...

I checked the buffers, there are buffer failures, in the router.. I think this could be because of that particular moment processor might be overloaded so it might not allocate the time for buffer allocating.. It was fine, and no problems with the same router and same interfaces.. but the problem arised only for last two days..

Strange Problem with router... [7:6293]
Hi, I am facing a strange problem from last two days. One of my 3640 router is behaving in a strange manner. Sudenly it is becoming 60 - 99 % CPU utilization.(Usally 20 - 30 %) at the same time It is droping the output packets on Main Serial link (which is using for uplink/downlink) and input packets on fastethernet (Used for LAN) port. Even these Interfaces are not overloading.. On the same router I am having 17 more serial links, and 1 more fast ethernet, and one ethernet interfaces and all are in working. I am using wccp v1, and BGP also on the same router. After Observing the problem I did the following things. 1) Increased the hold-queue to 4096 2) stopped the wccp and observed the status. But there is no use. It behaved in the same pasion. So I kept the things back. I am wondering.. if anybody help me.. The traffic is same and not varying.. but it is very much flutuating.. Please give me suggestions.. if anybody have any idea.. Thanks, Kiran PS: The router is not giving this problem continuously.. for 2 mins.. its working properly.. next 2 or 3 mins.. dropping the packets.. and next 2 mins.. working properly..

Please! Nothing wrong with having a single-area OSPF network, but number it ANYTHING except 0.0.0.0. Otherwise, if you ever need a second area, you have to change all your network statements so you can connect to the true backbone.

Re: Ram in 2500 series [7:6187]
Not any memory, but memory that meets all the specs. I don't know for sure what all the specs are (someone told me it was parity memory). The 2500 wil do max of 16M. I dug through my parts box and started plugging in memory untill I found a 16M that worked. It makes sense that Cisco wouldn't take the time and money to design some memory when there are standards in place and all they have to do is look through a book and pick a standard type. So moust routers will take some kind of standard (as well as most other hardware, for example HP printers). The one thing though I would only want to try it in a lab not a production environment where you may need to call Cisco for support.

RE: Backbones of backbones (was Re: Wanna Be a CCIE? [7:6274]
I've recently come across the debate with one of our customers over the below approach, versus using just an OSPF backbone. Their engineers are pushing for the BGP approach, I'm trying to understand the benefits. This message helps a lot! Couple of questions though: Is it possible to provision things like IP Multicast across a large enterprise using the below approach, considering the frailty of standards for deploying IP Multicast across BGP? What about situations like VoIP which require all sorts of any-to-any connectivity and might not be best handled by forcing traffic to transverse a common backbone? >From my experience, I'm starting to see a movement away from a hierarchical network toward a fully-meshed collection of end-points connected via IP tunnels (likely via MPLS?), with external tunnels to both owned and hosted data centers. Are you seeing the same? Fascinating discussion, this alone is worth the price of admission. Irwin -Original Message- From: Howard C. Berkowitz [mailto:[EMAIL PROTECTED]] Sent: Tuesday, May 29, 2001 2:51 PM To: [EMAIL PROTECTED] Subject: Backbones of backbones (was Re: Wanna Be a CCIE? [7:6274] I am a great fan of using separate OSPF domains, with the area 0.0.0.0's linked by a backbone of backbones. Most commonly, that backbone will use BGP, for exactly the reasons of control that Alan Robertson points out. I have had success, in specific networks, of building that backbone with static routes (including floating statics). These days, there are even arguments for using MPLS in the backbone as well. A Static Approach - One network in which I used statics had an Asia-Pacific, North American, and European region, plus a substantial corporate HQ in the US. There was a good deal of internal communications in each region, and substantial communciations with corporate, but not that much region-to-region communications. The Internet firewall was at corporate. It was reasonable to do the small amount of inter-region communications via the corporate center. Each region characteristically had different speeds in its backbones, DS3 in North America, E1 in Europe, and 64 Kbps in Asia. The connectivity back to corporate used international frame relay with international ISDN backup. At corporate, we set up a collapsed backbone LAN which had two routers for international use, each with a serial and a PRI interface so we could have diversity -- the backup ISDN link never went to the same physical router as the frame link for the same region. I did set up a small OSPF domain at headquarters, which mostly was for separation of corporate server farms from corporate user/local traffic, but also gave us a framework for connecting the networks of mergers and acquisitions. A BGP Backbone -- For a different worldwide customer, I chose a BGP backbone. Initially, each region was a single OSPF domain that appeared as a BGP confederation to the backbone. This company was in the shipping/logistics business, and, while some major data centers were in the US, there was very substantial inter-region communications, and communications from each region to the Internet. BGP let us control some fairly complex backup arrangements involving transoceanic bandwidth. It also facilitated the complex, multiprovider Internet connection strategy. >Peter, > >OSPF has a distance of 110, and yes, iBGP has a distance of 200.

Re: Question regarding Reverse Telnet [7:5999]
Thanks for the insight!I'm aware of how to use the aux port to
connect modems. I'm using that scenario with 2 external modems and a
teltone POTS simulator to do DDR. Works pretty good.

As Alan correctly points out, path cost is irrelevant in this case as intra area routers will be preferred over inter. >> We >> tend to think that a small network could not be better served by >> applying the same principles that we might use for a larger >> environment.

Re: Wanna Be a CCIE? Try This One [7:6076]
Couple thoughts on this. Cisco's OSPF should prefer intra area routes over inter unless the administrative distances are modified. By default, as many have mentioned, they are all set to 110. However, internally, I believe path cost is the 2nd tie break, with intra beating inter as the first. If this is the case (which it should be), modifying path costs whether directly or through other means will not influence the correct behavior. If this wasn't the case, the default metric calculation would already have traffic following the correct path as ABD is a lower cost path then ACD. Where they all in the same area, traffic would flow properly. Hence, the question is obviously what do you do? In my opinion, the design does not optimally reflect the constraints of the physical topology. I assume we are looking at a subset of a larger network inclusive of more routers? I would suggest a modification in the OSPF configuration or possible the routing strategy itself may be in order. What is the reasoning behind not running in a single area? In cases like these, I find we often spend more time looking for the complex technical kludge instead of stepping back and asking the now famous question "What problem are we(you) trying to solve?"
