EIGRP & Distance command [7:71220]
On router A, I have two equal cost paths, via neighbor B and neighbor C, to a particular EXternal destination. To begin with, I see both routes in the EIGRP topology table and also in theIP routing table. I played around with the 'delay' of the connecting links to ensure that router A sees the routes as equally feasible i.e. router A's feasible distance to the destination via both B and C is the same. So far so good. In order to prefer the path to the EXternal destination via router B, I decided to INCREASE the admin distance of the route being advertized by router C. Thinking that the route advertized via B would have a lower admin distance and would be prefered. I added the following configuration statements on router A Under EIGRP distance 175 172.16.50.1 0.0.0.0 10 Globally access-list 10 permit 192.168.1.0 0.0.0.255 The advertizing interface of router C has an IP of 172.16.50.1/30 The EXternal route I am trying to play with is 192.168.1.0/24. Results: No change to the admin distance of the EXternal routes :(( If the route that I am trying to modify the admin distance of is INTERNAL,this concept works fine! Is there something special that needs to be taken care to modify the admin distance of EXternal EIGRP routes?

RE: how about ccie salary in US? [7:71143]
I'd say diversity is the key. I know several CCIEs who, outside of R/S don't have much to offer in the way of skillset and they are not commanding as high of salaries as guys without a number but deeper and more diverse expertise. It totally depends on the individual, the need, the location and the experiences (which are unique to and every one of us). Will Gragido CISSP CCNP CIPTSS CCDA MCP Suite 325 9450 W.

As far as the original question, so much depends on your experience level, the geographical location, things like holding a degree (or not).

Re: OT/Look at the requirements of this position!!!! [7:71173]
My read on this job post is that they do know what they need, they're looking for someone who is an expert in NT, Exchange and Citrix which is deployed at 30 sites in 5 countries and growing. As such they need to be able to add and maintain servers in a WAN environment and understand the implications of running these apps over those links. A CCIE may or may not know said applications in depth enough to maintain or even may not want to maintain them to the degree that is needed. Now if a person were to send a resume that listed MCSE and CCIE on the resume then the only reason that I can see for them not wanting them would be the cost of such a person or lack of knowledge with one of the core requested disiplines. - Original Message - From: "Kevin Wigle" To: Sent: Monday, June 23, 2003 6:37 PM Subject: Re: OT/Look at the requirements of this position [7:71173] > or perhaps the opposite. > > Maybe the HR person is fully aware of what they're asking for. > > Perhaps a CCIE is over qualified for the position - in their opinion. > > Kevin Wigle > > - Original Message - > From: "Ware, DavidE" > To: > Sent: Monday, June 23, 2003 3:38 PM > Subject: RE: OT/Look at the requirements of this position [7:71173] > > > > Who ever the hiring manager is, he or she lack's an understanding of the > > progression on Cisco certifications.

Re: bgp network & sending subnet and more specifics [7:71073]
Hi, is this only an exercise or you really need to do this? If the latter, then I would be curious to know why this would be useful. I feel a slight contradiction in that you can't control whether a /24 or two /25 routes reach you yet you seem to know what is in one half versus the other half of the /24 network and want to make some routing decision based on this knowledge. Anyway, to answer your question, the obvious solution is to point the two /25 static routes towards where you learn the /24 route from, not to Null0. If you have only one IGP peer, then simply point them towards it. If you have multiple IGP peers, then it gets a bit ugly. You could create a loopback address on the router where x.x.x.x/24 (or the two /25 networks) is directly connected, advertise the loopback(s) through the same IGP protocol which carries the x.x.x.x/24 route, and point the two /25 static routes to the loopback address(es). Or (assuming the IGP is OSPF and x.x.x.x/24 is in another area) you could use the loopback address of some backbone routers (possibly creating multiple pairs of static routes, each with different admin distance pointing to a different backbone router). The main thing to note in either case is that if you ever, for any reason, happen to advertise back these /25 routes towards where you learn the /24 route from, or if the router you pointed your static route to ever thinks that your router is the best way to get to x.x.x.x/24, then you just created a routing loop. Btw, why is it that "the IGP will only send the /24 and not the two /25s"? Getting the two /25s instead of the one /24 might be as easy as configuring a secondary IP address on that interface or (selectively) disabling summarization. This of course depends on your situation, so just something to think about...

- jvd wrote: > > OT: > hi, i just have to say that i will never try to answer anything > on this forum again. :-) Well, would that be Grumpy, Bashful, Sleepy, or Dopey to do that? :-) Seriously, you should keep answering. You have sent some great answers, but you don't want to keep insisting something when replying to my messages. It makes me very Grumpy and I'm not Bashful when wielding a keyboard (just in person). I know lots of books claim that NetBIOS isn't routable, but I bet those exact same books also classify it as a session-layer protocol. And it does make a good example of a session-layer protocol. One of the few that we have! And if it runs at that layer, then it is routable. I think even IBM said it was a session-layer protocol in some of their early documents, which unfortunately, I recently tossed. Directed broadcasts came from out of the blue. I really don't think Windows networking uses them, although maybe it does. Was the comment maybe in reference to the helper address suggestion that I made? You can tell a router to send the packets when "it helps" as a broadcast. That's not a directed broadcast, though, and will work even if router forwarding of directed broadcasts is disabled, which is the default these days. Instead, it's a broadcast sent by the router (it has the router's IP address as source, on behalf of some other station, to a local LAN, because the router is acting as a proxy, for example, a DHCP Relay Agent.) Was that a run-on sentence, or what? :-) A directed broadcast is directed from afar into a subnet. The sender usually makes classful assumptions, since it can't actually know the local definition of a broadcast. It's used by ping scan to send a ping to 172.16.255.255, for example, in an attempt to ping everyone on network 172.16.0.0. Routers don't forward those these days because of the security risks. Back to NetBIOS. It does send a lot of broadcast traffic for naming purposes. In an IP environment, however, a host can be configured to send unicast naming queries and name registrations to a WINS server. There are probably lots of other issues, though. It really can be quite a pain to get it to work correctly when you migrate from a small LAN to a larger internetwork with WANs, subnetting, VLANs, etc. I wonder what the original poster is really trying to do and where he can get a good Windows networking (internetworking) design guide. Cisco used to have one, but it's probably way dated now Well, it's late and my writing is deteriorating. Howard covers directed broadcasts, by the way, (and a much better description of the OSI model, without reference to the dwarves, as I recall, although possibly with reference to the deadly sins) in his CertificationZone papers. I recommend them.

Raise it > again if they > want to value there flagship cert. Everyone would agree w/me > that the value > of the cert has a lot more value than the value put in to > obtained the cert. Well... First, let me address your last sentence. I don't think the value is anywhere near as clearcut as you're implying. The value proposition is only clear if you pass in your first few attempts. But I know guys who have tried the test 10 times or more, all out of their own pocket. When you include travel costs, costs in personal time, and all the ancillary stuff, then the value proposition becomes very dicey. For example, I know a guy who has sunk more than $20 grand of his own money on testing (including travel costs, costs to get and maintain a home lab, interest, etc.), still hasn't passed, and if and when he ever does, I don't think he'll ever come close to ever making his money back. He's still trying because after you've sunk all that money, you really have no choice but to keep going (it's not like if he stops now he'll get his money back - what's spent is spent), but he knows and has admitted that this was a financial bloodbath for him. However, the crux of your argument is definitely true. Cisco has ample room to raise the costs of the test. A lot of candidates don't pay anyway because they're backed by their companies, so what do they care about the price? Cisco could tell all that found money and do all the things I and others have been proposing for awhile now.

RE: load [7:71198]
Load interval does not provide a backup of any kind, it is used to change the interval at which the router will query the interface for load (i.e, I/O bits/sec).

RE: CCDA Study material [7:71111]
Priscilla has hit the nail on the head as usual! If you don't have the experience with Cisco's AVVID, SAFE and voice architecture design, you should wait a few months for the self-study guides from companies such as Cisco Press and Sybex before tacking the CCDA DESGN 640-861 exam. I took the exam late last year when it was in beta and it's a real bear for an "intro-level" certification. I wrote an exam review you might want to look at for more information.

Re: netbios [7:71084]
There are too many smart arses around sometimes. The whole idea of a discussion group isn't for everyone to "Provide the right answer or beware". I think everyone would like to have a go sometimes, but there's that nagging doubt that you're going to make a big slip up. It's better I think when people have a go. It's amazing how many people answer the easy password recovery type questions, but no one is listening when the toughies come out, even though a lot of people could have a stab at it (guilty myself). Some people would end up on their arse if they replied face to face, the way they do in some follow up posts. Good on you - I will try to do my bit by making a fool of myself at every opportunity.

Re: 3745 stumper [7:71136]
The crashinfo file should still be available. Cisco routers operate on a Unix based file system, so navigation through the router's filesystem is similar. Cisco IOS creates a "crashinfo" file in the bootflash directory when a router crashes (mid to higher end platforms). To access this file, you would; log into device in privliged mode issue "cd bootflash:" command (don't forget the colon) issue "dir" command to see if crashinfo file exists, if it does then you can view it by issuing "more bootflash:crashinfo_-xx (where x=numbers in your device's filename) or you could send it to vendors for inspection as the following example: UMC#copy bootflash:crashinfo_20020908-131806 tftp UMC#cd system: UMC#dir Directory of system:/ 2 dr-x 0memory 1 -rw-8624running-config 16 dr-x 0ucode 27 dr-x 0vfiles No space information available UMC#cd bootflash: UMC#dir Directory of bootflash:/ 1 -rw- 3857148 Aug 19 1999 07:18:41 rsp-boot-mz.111-28.CC.bin 2 -rw- 163474 Mar 15 2002 08:14:51 crashinfo_20020315-141451 3 -rw- 195202 Sep 08 2002 08:18:06 crashinfo_20020908-131806 7602176 bytes total (3385964 bytes free) UMC#pwd bootflash:/ I am suprised by the findings of your testing though, as I myself ran extensive testing on a demo 3745 (NetIQ Chariot-70 + tests with various scripts including HTTP and HTTPS, & IPERF for load testing) with the DS-3 and ATM IMA cards and did not run into the problem you described.

reboot the bridge try a different crossover cable. can you set them both to full-duplex? (probably not on the bridge) can you recreate the problem by connecting the bridge to another router to test it? is this problem new? is any of the equipment new?

RE: Ethernet Interface Collisions Incresing rapidly [7:71176]
Collisions would be normal on a 10 half link, but the output errors are a little odd. Are the interfaces reporting late collisions and interface resets also? If so, I would try changing out the cable, late collisions/repeated interface resets usually indicate a bad cable or bad hardware. Of course, you could just be trying to stuff too much data down the link, what is the average bandwidth utilization? -Original Message- From: neil K [mailto:[EMAIL PROTECTED] Sent: Monday, June 23, 2003 4:13 PM To: [EMAIL PROTECTED] Subject: Ethernet Interface Collisions Incresing rapidly [7:71176] One of my Cisco router's Ethernet interface connected to a Cisco Wireless Bridges has the interface collisions counter increasing rapidly.

You aren't losing it. :-) We haven't said our usual answer yet. Send us the configs. Also he never told us anything about subnet masks. Maybe he's doing something weird with them, but probably not. Maybe on the Frame Relay interfaces, he's just mapping to the Ethernet sides and the serial interfaces don't know how to send to each other?? Can he ping or trace route just between the serial interfaces on the routers? I don't think he's told us that. Can the routers ping their own serial interfaces? Probably not. If the routers can't reach (from a L3 point of view) each other's serial interfaces, then Router B can't forward the ICMP TTL from Host B to Router A's serial interface, which is what he said was the problem at one point... I was suspicious of Host B, but we do need to see the router configs too. Does my explanation make sense!?

RE: Ethernet Interface Collisions Incresing rapidly [7:71176]
Collisions go up normally with load. What is the load? Could something else (an attack or trojan horse or just excitement about your terrific content) have caused the load to go way up? Cisco says that no more than 0.1 percent of frames should experience collisions. How many frames have there been in the time that the collisions went up? How does that compare to your baseline? By the way, why do you have the interfaces set to half duplex? Why don't you set them them to full since it's a point-to-point link?

Re: Router 827 ADSL + PIX 506 configuration [7:71059]
Okey Dokey - understood. If you're just playing around that's fine. You may have a few options. You could use your /29 for the subnet between router and Pix, but then you lose two of your 6 available addresses for the router and the Pix. Although you can grab some of these back, for instance by using port redirection on the outside interface of the Pix, so that port 80 goes to one of your web servers and 53 to one of your DNS servers etc. The other 4 addresses can be set up as static NAT through the Pix. Use Global (outside) 1 interface for outgoing connections to save using one of your addresses for general PAT. You could use a private address between the router and the Pix and just route your /29 at the Pix, then do NAT from there. You don't lose any of the 8 addresses then. You could still do port redirection, so one IP address doesn't have to be one server. Do as before and chip off port 80 for your web, and 53 for DNS etc. Good Luck Bikespace ""Lamy Alexandre"" wrote in message news:[EMAIL PROTECTED] > Because I would like pratice.

RE: Unable to copy from Sup-Slot0 [7:71038]
Yes, the main problem is that I'm booting into boot mode, which is why I want to copy an image into bootflash. As you probably know, the boot image is required in bootflash in order to boot to the main image. Just so you can see the whole process, I deleted the boot image from bootflash and started from scratch. As you can see, the boot image copies with no problem from sup-slot0 into bootflash. However, as soon as I try to copy the main image, it times out. I think I'll try formatting the flash card next and copy the images back onto it. Still no word from my TAC engineer. Shawn K.

That's strange, but it doesn't matter. You can still do some troubleshooting. Here are some questions to investigate. Why in your testing could Host B send a packet to Host A, but Host B couldn't send a packet to the serial interface on Router A? When Host B sends the traceroute to Host A, it's either sending a UDP or ICMP packet, depending on its operating system. That seems to work. All layers are working. It can send the upper-layer packet and it has a route to Host A. It appears that Host B can't send an ICMP TTL Exceeded message to the serial interface on Router A, however. That's the crux of the problem. (Traceroute depends on the routers and target host sending an ICMP TTL Exceeded message). What other testing have you done with Host B trying to reach the serial interface on Router A? Can Host B ping or traceroute to that address? At what layer does this problem reside? Does Host B really try to send the message? (Use Ethereal to see if it does.) If not, does it have a firewall that's blocking it? Probably not, since it can send a TTL Exceeded to Host A. So it's probably a network-layer problem. Does it have a route to the destiantation IP address (router A's serial interface?) What does "route print" tell you? What does "ipconfig/all" tell you? (assuming Windows) If UNIX, try route -n, netstat -rn, ifconfig. Of is the router somehow blocking the TTL Exceeded? That doesn't seem likely since it works in the other cases. I would focus on Host B. I think he's confused It could be a bug in the router, but something seems odd at Host B, as a first guess.

Though even if serially connected, with static routes you would not know if the LAN connection on the ISP router went down effectively causing the same blackholing you refer to. Like most things there is a cost/benefit analysis. WAN links are more prone to outages than the LAN, pointing your default to the ISP WAN is simple and commonly used config. For cusomters that are more sensitive to outages may opt for dual homing to 2 ISP's using ful routing and have their WAN connections via a SHNS or SHARP configuration. Redundancy and simplicity are not bedfellows and the more your willing to spend the more redundancy can be had.

You must be doing routing. It has nothing to do with Proxy ARP, though. Maybe you have on-demand routing or something. > proxy-arp doesn't function on serial interface. > so what's the real function of proxy-arp on serial interface ? Proxy ARP has no meaning on a serial interface. ARP has no meaning on a serial interface, (unless you're referring to Frame Relay's Inverse ARP, which is a different story. It finds the IP address when the DLCI is known.) Serial interfaces don't have MAC addresses. They don't connect devices that have MAC addresses. ARP finds the MAC address when the IP address is known. It's meaningless on a serial interface. If you configure Proxy ARP on an Ethernet interface, the router could respond to ARP requests on its Ethernet side on behalf of devices on its other side, (across the serial link in this case), assuming the router knows that it can get to those devices. That's the definition of Proxy ARP. > Does it work when bridge on the serial interface ? > If bridge on serial interface,how ios transfer arp ? I think > there isn't mac address on serial interface . Is there some > encapusation to packet the mac and transfer the lan frame > through serial interface ? If you were doing bridging, then the router interfaces would be passing all broadcasts, without any knowledge of what they were passing. So Ethernet devices could theoretically ARP through a bridged network that included WAN links. The encapsulation would be whatever was configured for the WAN links. It wouldn't matter. Bridging is transparent. I've never heard of anyone doing that and there might be some gotchas, but I think it would work. The ARP data has enough info in it for it to work. It doesn't care about the data-link-layer header that is used to transfer the request or reply.

Re: netbios [7:71084]
NetBIOS is a session layer protocol. Of course it's routable. Yes, it's true that IBM invented NetBIOS. NetBEUI was the name of IBM's software module that implemented NetBIOS. It usually ran in conjunction with TOKREUI, by the way, which was driver software for Token Ring. NetBEUI didn't make any calls to a network layer. It assumed it was running directly above LLC and made calls to LLC's interface. It also make source-route bridging calls, by the way. It's just semantics at this point but does point out a couple higher-level concepts. One, networking is more complicated than the simple statements like "NetBIOS is not routable" that you will find in Networking 101 papers. Two, it's important to understand that every layer makes calls to a layer below and every layer offers services to a layer above. Because the service interface of a layer, whether it be LLC or UDP, is well known (hopefully), any upper layer can call on it. So, an implementation of a session layer protocol such as NetBIOS can call on UDP, TCP, LLC, or IPX. That's the real message from the infamous OSI model. It's all about service interfaces.

I just noticed the inconsistent subnet masks. Of course, it works. The router in the middle knows how to get to each subnet using the /24 mask. The router on the left knows that all of the larger subnet is out its serial interface. It's a bug to have the two routers on the left using a different subnet mask to refer to the WAN subnet, by the way. Why worry about whether it works and how it works at all if you're using a buggy configuraton? :-) Priscilla > > > proxy-arp doesn't function on serial interface. > > so what's the real function of proxy-arp on serial interface > ? > > Proxy ARP has no meaning on a serial interface.

Re: netbios [7:71084]
Hi, I just want to make something clear. NetBIOS and NetBEUI were created by IBM and later found its way to Microsoft networks who changed it. - These protocols are non-routable in an IBM environment. - NetBEUI is non-routable in TCP/IP networks. - NetBIOS is non-routable without the help of NetBT. NetBT is NetBIOS over TCP/IP and was conceived in RFCs 1001 and 1002 to enable NetBIOS to be routed.

From a pure theoretical point of view, that seems a bit dangerous to me (to have two default static route pointing to two different routers). If one of the ISP routers is not directly connected to the customer's router (because for example there is an Ethernet switch in the middle), then the customer's router won't notice even if the ISP router is powered down. Even if the two routers are directly connected, it is possible (even though with current IOS versions it is not very likely) that the interface stays up even though routing dies on the ISP router. In short, I think there is a chance of you blackholing half of your traffic.

Re: Transporting Multiple Vlans over point-to-point [7:71074]
Alaerte, I can think of a couple ways to doing this. Be forewarned. Both are ugly. Method #1: Relocate the servers /30 subnet -- We'll say the server's IP address is 192.3.3.254/24. Create a secondary IP address on R2 for 192.3.3.252/30. R2's secondary address becomes 192.3.3.253/30, the server can stay 192.3.3.254/24. Make sure that R3 knows how to reach the 192.3.3.252/30 subnet (either static route or a classless routing protocol). How it works: Proxy ARP. Stations on VLAN 300 attempting to connect to the server will ARP for 192.3.3.254, for which R3 has a "better route", and will respond to the ARP with its own MAC. Traffic to 192.3.3.254 will be routed to R2. The reverse will happen when 192.3.3.254 attempts to respond to the client, it ARPs, R2 knows of a route and responds with its MAC, the packet is routed back. Other info: - I've assumed that the server address was 192.3.3.254, it could have been anything. The /30 subnet would change accordingly. - I've assumed that .252 and .253 were not already in use. If they were, connectivity to these stations would be broken. You can get around this problem by configuring (and redistributing) static routes for 192.3.3.252/32 and 192.3.3.253/32 pointed back towards Vlan 300 on R3. - L2 Broadcasts will not be available to/from the new server Method #2: Virtual router - This method has the unique property of being both cleaner (from a caveat perspective) and uglier at the same time. Imagine walking into this at a customer site -- how long would it take you to figure out what was going on? :) Once again we'll say the server's IP address is 192.3.3.254/24. Configure a static route on R3 as follows: ip route 192.168.3.254 255.255.255.255 (ip_of_R2) On R2, determine an IP address that isn't used for use as a virtual router. We'll say 192.168.2.254/24 isn't used. Create a static route on R2 to the server through the virtual router: ip route 192.168.3.254 255.255.255.255 192.168.2.254 The virtual gateway doesn't exist so pings to it will fail. Don't worry about that yet. Move the server to VLAN 200 without changing its IP address or mask. Determine the MAC address of the server. We'll say 0001.0002.0003. On R2, configure the MAC for the virtual router to be the server's IP: arp 192.168.2.254 0001.0002.0003 arpa You must perform similar steps on the server. We'll assume that its default gateway has not changed. We'll also assume that its default gateway was 192.3.3.1. Configure a static ARP entry for the default gateway that reflects R2's Ethernet MAC (0102.0304.0506): arp -s 172.30.16.254 01:02:03:04:05:06 Make sure that R3 knows how to reach the 192.3.3.254/32 subnet (either add a static route or redistribute on R2). How it works: Vlan 300 stations broadcast ARP, and R3 responds with its MAC (Proxy ARP). R3 forwards the packets to R2. R2 forwards the packets directly to the server (although it believes it is forwarding to another gateway). The server receives the packet because the MAC was correct, notices that it is the end station, and processes the packet. Traffic from the server to VLAN 300 is possible using Proxy ARP as describe in Method 1. Traffic to/from other VLANs (VLAN 100) will also work fine since the server forwards all of its "default gateway" traffic to the correct default gateway, R2. Other info: - I've assumed that the server address was 192.3.3.254, it could have been anything. - The only 192.3.3.0/24 address used on VLAN 200 (other than the servers IP) is the Ethernet IP address of R3. - L2 Broadcasts will not be available to/from the new server - Pings to the virtual router will fail (it /is/ virtual after all), even though the server will have full network connectivity. If you get around to actually doing either of these in the lab and run into trouble, let me know (the above was written from memory, and I may have missed a step or two). I originally came across these ideas after reading Doyle and configured them in the lab just to see if I could pull it off. Yep. :) You would be surprised with some of the crazy labs you can make for yourself when IP addresses don't need to be contiguous or need to match the local router! - Tom alaerte Vidali wrote: > Need to transport multiple Vlans over PoS. > > Any Thoughts? > > It is a short term need.

My guess is that maybe there is a problem with the buffer assignment, i.e. a memory problem, when you have a traffic rate approaching 200-300kbps. Cisco will probably fix this in the software.

That core > group > that gave the corp it's legs to stand on. I see that you are familiar with the works of Marx. Yet we are all familiar with how successful Marxism has been as an economic system. Allow me to inject some counterplay into your argument. First, it's not like those initial workers got nothing. At the very least, they got paid a salary. Secondly, when we're talking about the first few workers at a startup, more often than not those workers are handed pieces of equity in the form of stock options. Secretaries who worked at Microsoft from the very early days have gotten filthy rich precisely because of that equity. Third, and most importantly, it's not like those workers are forced to work there. They are free to quit whenever they want. If some other company offers them a better deal, they are free to take it at any time. So the analysis breaks down as follows. Let's say I create my startup company and I decide want to hire you as my secretary. So I make you some sort of compensation offer which you are free to accept or refuse. Obviously I have to give you some sort of offer that is comparable to all the other secretarial offers you may be getting from other companies, otherwise you're not going to work for me, you're going to work for those other companies. So let's say my company does does become big. Why exactly are you, as my secretary, entitled to rewards beyond what may be stipulated in any equity that I had agreed to give you? If I agreed to give you equity, then you deserve the appreciation of that equity, but nothing more. Did you really 'build' that company? Not really, most likely you just did secretarial work just like all the other thousands of other secretaries around the country do every day (for which you got paid just like every other secretary). So why do you have any unusual claim to the success of the company beyond what was agreed upon in an equity package? Just because you happened to be there, you deserve more benefits than the average secretary? I simply don't see it as "giving the core group its legs to stand on" - you did the same secretarial work as you would have done anywhere else and you were paid an accompanying secretarial salary just like anywhere else. Just because you happened to do that secretarial work at my startup company does not by itself give you claim to the success of my company. If you negotiated some equity in your employment contract, that's one thing, but you don't deserve anything more than what you negotiated. That's like saying that if my brother wins the lottery, I am somehow automatically entitled to part of it. If my brother wants to give me some of the winnings, that's one thing, but I have no right to demand it of him. If you think that you as a startup worker should enjoy the benefits from the success of the company, then by all means negotiate yourself an equity stake. Generally, startup negotiations tilt on how much salary you get vs. how much equity you want. The more equity you want, the less salary you are offered. Nowadays, I see that most people are leaning towards more salary and less equity because of the dotcom bust. But the point is, if you choose to trade salary for equity, you can't return later and say "do-over" if the company becomes big. If you agreed to trade equity for salary, then that was your choice. After all, what happens if the company doesn't do well - I can't say "do-over" either, I can't just give you equity in lieu of salary, I have to pay you what I said I was going to pay you. >Along comes Joe or > Josephine > CEO, president, or whatever.

Re: Proxy [7:70959]
Gbenga, Proxy Server 2.0 was the last version released before ISA server, and it did not support transparent proxy. Supporting transparent proxy is important here, since the HTTP header for a proxy request will always contain certain lines (such as "Host:"), whereas direct HTTP 1.0 requests may eliminate these lines. For a proxy server to work correctly, it is important that it know both the destination IP/host and the URL. If the proxy does not receive all of the required information, it can't service the proxy client. I am more familiar with Squid (I don't know whether Squid is supported on Windows) which can be configured to fix-up HTTP requests on the fly (recreating the Host line from the URI for example), allowing it to be used as a transparent proxy... IP helper addresses don't apply to the problem you are trying to solve. Policy-based routing and WCCP won't do anything for you either, since you are limited by the Proxy server. You either have to use the bundled Proxy client software to force users to use the proxy or use a different proxy server. - Tom OLUGBENGA BANKOLE wrote: > Tom, > I refer to Microsoft Proxy server. i.e can I direct traffic to a microsoft > proxy just like I would a DHCP server by using the ip helper address command. > > > Regards, > Gbenga > > > To God be the Glory.Gbenga. > > - > Do you Yahoo!? > SBC Yahoo!

Re: Loopback subnet mask [7:71121]
Hi, IMHO it is technically incorrect to configure anything but /32 on a loopback. Last time I checked, OSPF in IOS advertised the loopback address as /32 regardless of the configured mask, but other protocols did not (ie. they advertised the mask as you configured it). So if you ever configure two or more loopbacks with /24 and they happen to be in the same subnet, and the routing protocol happens to advertise this information as you configured it, then you will have an unreachable loopback.

Directed broadcastes are less of a burden as far as passing brodcasts for specific apps. indeed netbios is not routeble, to route it u use NBT or NBIPX ""Priscilla Oppenheimer"" a icrit dans le message de news: [EMAIL PROTECTED] > koh jef wrote: > > > > hi guys, > > > > can netbios,using port 137, 138 and 139 be routed thru WAN ??? > > NetBIOS uses UDP and TCP which run on top of IP, which is routable over an > IP internetwork, including WAN links. > > Routers don't forward broadcasts though, by default.

RE: Passed BGP Beta and Switching 640-604 [7:71115]
Grant, Thanks for your suggestion, though I am not sure what the 350-001 exam is all about - CCIE written? Honestly, I doubt whether that is my goal.I will not be able to get the necessary equipment to play with. Also, in my country, I will be overqualified :) That is correct: in some countries, being a CCIE means being overqualified. In any case, I am actually already overqualified when it comes to the company employment situation in my country; I can only work as a consultant and/or Instructor :). Thanks.

RE: Traffic share count [7:71116]
OSPF doesn't allow you to do a unequal cost load balancing . With EIGRP , this can be achieved by using the "variance" command ( under "router eigrp" ). The " traffic share count " value is an indicaion of how many packets would be transmitted over the various paths ( equal cost ( in which case it is 1:1 ) / unequal cost ). With the use of the " variance " command in EIGRP , the router can be made to transmit traffic in ratio proportion to the metric of the unequal cost routes. Please find below the copy-paste from the Cisco Site which gives more clarity . -- EIGRP puts up to four routes of equal cost in the routing table, which the router then load-balances. The type of load balancing (per packet or per destination) depends on the type of switching being done in the router. EIGRP, however, can also load-balance over unequal cost links. Note: Using max-paths, you can configure EIGRP to use up to six routes of equal cost. Let's say there are four paths to a given destination, and the metrics for these paths are: path 1: 1100 path 2: 1100 path 3: 2000 path 4: 4000 The router, by default, places traffic on both path 1 and 2. Using EIGRP, you can use the variance command to instruct the router to also place traffic on paths 3 and 4. The variance is a multiplier: traffic will be placed on any link that has a metric less than the best path multiplied by the variance. To load balance over paths 1, 2, and 3, use variance 2, because 1100 x 2 = 2200, which is greater than the metric through path 3. Similarly, to also add path 4, issue variance 4 under the router eigrp command. How does the router divide the traffic between these paths? It divides the metric through each path into the largest metric, rounds down to the nearest integer, and uses this number as the traffic share count. For this example, the traffic share counts are: for paths 1 and 2: 4000/1100 = 3 for path 3: 4000/2000 = 2 for path 4: 4000/4000 = 1 The router sends the first three packets over path 1, the next three packets over path 2, the next two packets over path 3, and the next packet over path 4. The router then restarts by sending the next three packets over path 1, and so on. Note: Even with variance configured, EIGRP will not send traffic over an unequal cost path if the reported distance is greater than the feasible distance for that particular route. -- Hope this clarifies .

It is about the meaning of "traffic share count" that I can see when I execute an "show ip route" command: Router#sh ip route x.x.x.x Routing entry for x.x.x.x/28 Known via "static", distance 1, metric 0 (connected) Routing Descriptor Blocks: * directly connected, via Serial5/0/0/1 Route metric is 0, traffic share count is 1 I guess It has something to do with load balancing, but I would appreciate any comments about it because even when there are several routes to the same destination I can see that the share count is 1: Routing entry for X.X.X.X/29 Known via "ospf 1000", distance 110, metric 20, type extern 2, forward metric 5 Last update from X.X.X.X on ATM0/0/0.10061, 03:52:56 ago Routing Descriptor Blocks: * Y.Y.Y.Y, from W.W.W.W, 03:52:56 ago, via ATM0/0/0.10060 Route metric is 20, traffic share count is 1 Z.Z.Z.Z, from V.V.V.V, 03:52:56 ago, via ATM0/0/0.10059 Route metric is 20, traffic share count is 1 How can this value be changed?

Thank You, guys. Passed Foundation Exam.640-841 [7:71127]
hi guys, I'd like to thank for this groups, I've been followed your discussion And it's really useful and delightful being part of it. I just passed foundation exam 640-841, routing - 880, switching 960, remote 940 question 110 , 40% routing, 30% switching , 30% remote got simulation question on routing ( multi area of ospf basic configuration ) and remote ( frame-relay traffic shapping ) Must be familiar with show of routing protocol ( ospf, eigrp, is-is , bgp ) kind of routing protocol timer..hello, dead, knowing detail of mls, multicasting protocol, vtp mode, hsrp mac address, stp root bridge selection when to use cisco remote access product , isdn configuration - PRI, triple aaa usage, x25 map, click and drag question of queueing technology.. scrutinize the detail of foundation blue print... hands-on as much as possible. and now I am focusing on CIT.. anyone who takes recently can share his/her experience... any simulation question ? cheers hin 3/4... :) Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=71127&t=71127 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

i actually have not tried this, but, if u configure a tunnel, u don't need a virtual link, since ur tunnel will up to the backbone, in which case direct adjencency of the areas, but since i have not tried this, i don't know if it works.
