RE: Advanced NAT problem [7:66562]
ONe would hazard a guess ... when you initiate you orginal ping a nat translation is built using the outside address of your leased line, when you pull ou the leased lin cable, this translation is still present and that is why you pings are failing. By tearing down the connectiong and restarting your ping, you setup a new xlate and thus pings are succesful. I am not sure if there is a way to remedy this. You could have a fast timeout on your translations, but the upper layers will pick up that a packet hasn't been delivered and resend (with the now new xlate and packets will get through), so nothing really to worry about in my view !

static NAT and Overload [7:66602]
Hello people, I have a question about NAT. Is possible configure IOS for "ip nat inside source static" and "ip nat inside source list overload" in the same connection ?. In other routers (Zyxel,Efficient,3com) this technique is designate how "monouser or multiuser". I explain this, I need redirect all ports of Public IP to local IP, but I too need that others users can connect to internet for the same router and connection. Configuration monouser (this run OK, but only PC 192.168.10.2 can connect to Internet) interface eth0 192.168.10.1 ip nat inside interface dialer 0 ip address negotiated (ISP give me allways the same IP) ip nat outside ip nat inside source static 192.168.10.2 80.10.10.1(IP ISP) Configuration multiuser (this run OK, but I don't want this) interface eth0 192.168.10.1 ip nat inside interface dialer 0 ip address negotiated (the ISP give me allways the same IP) ip nat outside ip nat inside source list 1 interface dialer 0 overload access-list 1 permit 192.168.10.0 255.255.255.0 Configuration monouser and multiuser (Only run PC in the static NAT, I want others PC too connect) interface eth0 192.168.10.1 ip nat inside interface dialer 0 ip address negotiated (the ISP give me allways the same IP) ip nat outside ip nat inside source list 1 interface dialer 0 overload ip nat inside source static 192.168.10.2 80.10.10.1 access-list 1 permit 192.168.10.0 255.255.255.0 I know for my experience, this is possible in routers Zyxel. With this configuration you can use netmeeting,msn,etc and other softwares that don't run very well before NAT . This is limited to only PC, the PC or IP configurated in "static NAT".

RE: pathping question [7:66601]
Not necessarily, it could just mean that ICMP replies are disabled. Traceroute doesn't use the same mechanism as ping, and thus traceroute will give you end to end connectivity, but by trying to get response times using ICMP ping wont work as many people disable this. (Meant to minimise reconaissance scans). Richard Campbell wrote: > > Hi.. I forward you a part of the pathping result to my web > server, can you > take a look on the 15th and 16th hop.

CAS and CCS - out-of-band and in-band [7:66607]
The URL following states: "Channel-associated signaling, which uses E1 time slot 16 (the D channel) for signaling, fits into the out-of-band signaling category." "Robbed-bit signaling, which uses bits from specified frames in the user data channel for signaling, fits into the in-band signaling category." Robbed-bit is used in T1-CAS. So I can say E1-CAS is classified in out-of-band signaling and T1-CAS is classified in in-band signaling. Is that right? I have seen questions stating that CAS is just one thing, in-band signaling.

Hello group, How does one feel about a career in MPLS...I mean doing MPLS as part of your core job day in and out.Is it worth it? Since our network does not use MPLS (maybe never will) inspite of being one of the Big Four Tier 1 SP'sare there other SP's that use MPLS in their backbone?? I have just given myself a month or so break from my CCIE Lab Prep.(yeah!yeah! most would consider me stupid on this) to study MPLS for the CCIP and am thinking if I should pursue this subject just like I did for BGP.know it inside out cold.and maybe consider a new career/job in MPLS (obviously along with BGP, MBGP, MCast etc...) Does anyone know of how MPLS is viewed out there? I mean, in terms of implementation, popularity and last but not the least , $$$ ??? ;->Which of the Big SP's or Enterprise networks have implemented MPLS? Has it been worth the advantages that MPLS proposes??Thank you.Sincerely,CN Add photos to your messages with MSN 8. Get 2 months FREE*.

The following are the configs nterface Ethernet6/0 no ip address half-duplex pppoe enable pppoe-client dial-pool-number 1 dial-on-demand ! ! interface Dialer0 ip address 2.2.2.2 255.0.0.0 encapsulation ppp dialer pool 1 dialer idle-timeout 180 either dialer hold-queue 100 dialer-group 1 no cdp enable ! ! interface Dialer10 ip address 3.3.3.3 255.0.0.0 encapsulation ppp dialer pool 1 dialer idle-timeout 180 either dialer hold-queue 100 dialer-group 1 no cdp enable Any help is appreciated.

Has it been > worth the advantages that MPLS proposes??Thank you.Sincerely,CN The way I see it is this. MPLS is potentially powerful technology for it can be used as a lingua-franca among a carrier's network and transport layer and also as a way to impose circuit-switching discipline upon IP and therefore offer circuit-switching services with a pure IP network. But MPLS is by no means a slam-dunk. Certain carriers, most notably Sprint, have elected not to go down the MPLS path because they believe the technology is immature (and they are correct) and also because they believe that they can garner the benefits of MPLS by other means (also correct). The point is that while MPLS offers great potential, it also presents problems, so implementing it is not a no-brainer. And furthermore, I don't particularly like the way that Cisco is pushing MPLS, particularly in its cert program. In my opinion, I think Cisco's cert programs emphasize the least useful parts of MPLS while neglecting the more useful parts. For example, I don't understand why Cisco pushes LDP the way it does, for LDP merely builds LSP's that correspond to the route table, but what's so useful about having LDP's that look like the route table? It is far more useful to build LSP's that differ from the route table, but the methods of doing that are not really covered very much (if at all) in the Cisco curricula. Also, I don't understand why Cisco places such an emphasis on L3VPN's, as if L3VPNs were the only important service that MPLS enables. L3VPN's are only one of the new services that you can enable, and in my opinion, one of the less important ones. Far more important are the L2VPN capabilities and the ability to unify IP, ATM, and optical into a single management plane.The point I'm making is that if you merely study MPLS according to the Cisco curricula, you really haven't learned much about it that's actually useful. > > > > Add photos to your messages with MSN 8.

NT domain access after connecting through VPN [7:66618]
I am using a PIX and VPN client 3.6 and getting in works just fine. Problem is I want to connect to NT domain resources across the board after logging into VPN. I know you can connect to network shares using alternate username and password but for things like remote event logs on the domain, you don't get prompted and will be denied. I am aware that you can have VPN connect before logging into Windows and then log into the domain after VPN is connected but I don't want to alter people's computers that are logging in locally. I would rather get access to the domain after logging in locally and then the VPN.

You have to apply the ACL to the vty line to allow telnet into the router, so it won't have any affect on incoming traffic from HQ to the LAN. If that weren't the case, then yes, I see why you would want that line. I understand now why you had it in there. Good luck with it.

Cisco and other documents consider the use of E1 time slot 16 to be out-of-band signaling because it's an entire channel used for signaling instead of using bits that are in-band with the data bits. It could be CAS or it could be CCS. Channel-Associated Signaling (CAS) means that the channel is structured in such a way that each data channel can use some bits for its signaling. Common Channel Signaling means that the signaling channel is unstructured and could be used by any data channel that currently needs it. That may be a gross over-simplification. Someone can correct me if I'm confused. It's weird that they threw ISDN into the statement (by saying the D channel in parentheses.) ISDN PRI uses CCS, doesn't it? I guess I'm not sure about that. I've seen that it does, but that might have been the CVOICE class, which really did munge this topic. > > "Robbed-bit signaling, which uses bits from specified frames in > the user data channel for signaling, fits into the in-band > signaling category." > > Robbed-bit is used in T1-CAS.

Jeff Doyle is a well known name, and I really enjoyed reading both of his volumes on Routing TCP/IP. However, I don't know that thescenerios such that BGP in Volume II will be helpful in CCIE Lab exam. It requires alteast 8 or 9 routers. His scenerios aremore towards real world rather than CCIE Lab. Does anyone think it is worth going through the practical scenerios he presented in his Volume II? They are good for getting a goodgrasp on BGP though? Any recommendations for CCIE Lab BGP scenerios?

RE: Router-to-external MODEM connection [7:66585]
You didn't mention which version of 1600 you have. Here's a cut from a Cisco document: "The serial WAN port on the Cisco 1601 R router supports asynchronous serial connections of up to 115.2 kbps and synchronous serial connections-such as Frame Relay, leased lines, Switched 56, Switched Multimegabit Data Service (SMDS), and X.25-of up to 2.048 Mbps. http://www.cisco.com/en/US/products/hw/routers/ps214/products_data_sheet0918 6a0080091ff4.html So, if you have a 1601R, the answer is yes you can connect a modem. I'll assume the interface is 60 pin. The cable for that would be a CAB-232MT= 60 pin to 25 pin EIA/TIA 232 male. Configure your serial port to be asynchronous. Your serial int will have a different number. R1(config)#int s5 R1(config-if)#physical-layer async See if it changed interface Serial5 physical-layer async no ip address ! line 5 ! You can do a "show line" as well. Then configure the line.

Re: A career in MPLS..... [7:66609]
Let me say up front, I don't have much experience in MPLS, I have only played with it in the lab and not all that extensively either. But CN is simply trying to get an idea of what to expect to go that road. Is "nrf" saying not to advance in this field by studying Cisco's way of emphasising MPLS ? You know, we all have our doubts, he's brave enough to come to this group and ask questions. As far as L3VPN's, why not concentrate on that at least to start with. It's still one reason to do the MPLS thing. By just doing that he'll need to touch on many aspects of MPLS anyway. He will still use either LDP or RSVP, he still will use the LSP establishment, he might as well learn the TE options available for establishment of those LSP's. He'll need to learn how to use the LSP's for pushing traffic over them. He'll learn what and how the labels get pushed/popped. Then why not study it that way. He's not advancing his MPLS skills, he might not have any yet. He's simply trying to see if he will be able to utilize any of the skills he will have to learn to make it worth it his while. Well, maybe someone else with more experience in MPLS arena and someone more objective can give a better insight as to whether there is a demand for these skills.

Just kidding. :-) Seriously, it really depends on your configuration and where the redistribution is taking place. It gets to be more difficult as your routing table grows, but show ip route is as good as any command. If you see any routes that say "possibly down" that's a good indicator that you might have issues. Another sure sign is if you see routes originating from the wrong domain, e.g. routes originating in the OSPF domain showing up as EIGRP routes. Another way to tell is to use 'debug ip routing' and watch the changes in the routing table as they take place. If you have a routing loop, you might see evidence of this by watching the route installation process. Two other tools that are handy: traceroute and extended ping. If you use extended ping, set the record route option to see the path the ICMP packets are taking. There is no simple command for hunting down routing loops. The 'simplest' way is to become familiar with the way things _should_ look so you'll notice when things don't look like they should.

you'll need a WIC with a async/syn serial port, I know they're available for the 1700's, but I'm not sure if the same wic will work in a 1600. then you can specify the interface as async and connect up the modem with a db60-rs232 cable. scott ""Diego Martmnez Boqui"" wrote in message news:[EMAIL PROTECTED] > Hello Steve, yes, I can do this using the aux port but my 1600 router does > not have an aux port, I need to do this using my serial sync/async > interface, I just don`t know how and have not found a document about this > type of connection. > > Thanks for your help anyway > > Peace > - Original Message - > From: "Steve" > Date: Tue, 1 Apr 2003 03:21:41 GMT > To: [EMAIL PROTECTED] > Subject: Re: Router-to-external MODEM connection [7:66585] > > this can be done look for cisco doc to connect external modem to aux port > > -- > Regards, > > Steve > > > ""Diego Martmnez Boqui"" wrote in message > news:[EMAIL PROTECTED] > > Hello Group. > > > > Is it possible to connect an external modem to a Cisco 1600 series > > router? > > > > And if it is, then how is it done? > > > > Can I connect using the serial interface? > > > > Any link with step by step instructions? > > > > Thank you all! > > -- > > __ > > Sign-up for your own FREE Personalized E-mail at Mail.com > > http://www.mail.com/?sr=signup > Diego Martmnez Boqui > > -- > __ > Sign-up for your own FREE Personalized E-mail at Mail.com > http://www.mail.com/?sr=signup Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=66632&t=66585 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Yes you do need to fire up QoS on all links, sounds like serialization delay may be killing you on the lower circuits, which means you need to turn on LFI as well. d- -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Hitesh Pathak R Sent: Sunday, March 30, 2003 10:21 PM To: [EMAIL PROTECTED] Subject: Cisco Callmanager with ATA's [7:66524] Dear Group, Need you help in resolving this configuration issue. Below is the setup that I am trying to do :- CiscoCallManager->LAN SWITCHLAN SWITCH | | 2 MBPS| | | | 64 K | 64K| | | | | Cisco ATA Location X Location Y Cisco ATA (2 Phones) With ATA With ATA(2 Phones) (2 Phones) (2 Phones) Setup :- 1) Cisco callmanager resides at Headquarters. (CCM version 3.1(3a) ) 2) The link between HO & RO is 2 Mbps (Voice + Data ) 3) The link from HO to its nearby location is 64k & similarly the link between RO & its nearby location is 64K (Voice + Data). However there are many locations & are connected to HO & RO via Channelised E1 & 64K each. 4) All the locations are having Cisco ATA's where we have option for connection 2 analog phones (FXS ports) 5) In Cisco callmanager following things are configured - (a) Location for every place - for call admission control with 48K as BW (b) region for every location (c) Pool for every location. 6) The codec used between all the WAN locations is G.729 except the locations HO & RO. Between HO & RO where there is 2Mbps the CODEC used is G.711 (Here if we try to enable G.729 as the codec then the voice calls are not going thru.) Problem - The voice calls are going properly w/o any problem between location X & Location Y with a good audio quality.The voice calls are also going fine between HO & RO on 2Mbps link. But the voice quality between Location HO & its nearby location X is very bad (Both Ways) . Similarly the Voice quality between RO & its nearby location is again very bad (Both ways). Can anybody tell me why am I getting this issue only on 64K link. My requirement is that atleast one voice call should go thru at any given point of time along with data. What settings do I need to check from the Callmanager side ?? & from the locations side ?? Do I need to implement QOS between all the WAN locations ??

If a recipient notices a hole in the bytes received, it doesn't ACK the last byte received. It ACKs the last byte before the hole, which it probably already ACKed. ACKing the last byte received would give the wrong impression that all bytes were received and no indication that some are missing. This should be explained in the TCP RFC or it might be in the Host Requirements, or maybe you just have to see it to understand it. Back when networks were less reliable and packets got lost for all sorts of reasons, it was easier to see examples of this with a protocol analyzer...

Re: A career in MPLS..... [7:66609]
I don't mean to start any type of argument here, especially with someone who obviously has more experience than I do. Yes, you've been contributing to this study group many times. But also many times your contributions are rather rethorical than practical and at the same time you seem to draw attention to what your opinion is rather than to give an educated and objective view backed by any type of real life examples. So yes, I'm saying that some times you don't quite stick to the subject at hand. I don't see how your view on Cisco's curriculum in re to MPLS can be taken seriously without you putting actual examples of how you came to that conclusion. Even if the knowledge required for achieving Cisco's recognition in re to MPLS was not as advanced as one would hope, shouldn't we look at positives of the whole process ? There are still things to be learnt, and emphasising them rather than the weaknesses would be a better idea. You won't become an expert just by passing the test or taking a trainig class, but at the same token, you can still learn a lot while achieving those CCXX goals. Anyway, I'm sure there will be a good response coming, so let me be done with this subject. I had an early start today and I'm tired now. Good night !

CCNP Recertification Exam Review [7:66644]
The CCNP Recertification Exam was gruelling, and that's no April Fool's joke. But I survived it! ;-) Exam number: 640-851 (the current one) Number of questions: 112 Time: 2 hours Passing Score 732 My score: 834 Is anyone else taking it soon? Here's some advice: Do study. Take each question one at a time. There's plenty of time. Despite some of the gruelling questions, there are some give-aways too. Read carefully. Don't guess unless you absolutely have to. BREATHE! ;-) There's a variety of question types, including one right answer, multiple right answers (they tell you how many), drag-and-drop, type in the command, select a command from a list, and that new simulator thingie that Cisco uses. One reason the test is so hard is that it covers so many topics, in quite a lot of depth. After a while, your brain gets fried and you forget, is it OSPF that considers a high priority a good thing (for DR election) or it STP that considers a high priority a good thing (for root bridge election?) (It's OSPF). And with OSPF, does a 0 in a mask mean "must match" like in access lists or does it mean "don't care" like in static routes (and OSPF range commands?!) (0 means must match in OSPF network statements.) Those things may seem obvious, but by about question 72, you start to get confused, if you're like me. You just have to relax and realize that you DO know this stuff. Don't let your brain get into a Mobius strip like mine almost did. The good news is that the questions from the different qualifying tests are not merged. It's very clear when you move between the following tests: Routing: It's based on BSCI actually, not Routing, and is quite hard. Know your BGP, OSPF, and IS-IS. I used Doyle and papers at CertificationZone. You won't be able to just use books that you read when you passed 3 years ago. Support: This didn't seem to have changed. So you could use the Cisco Press CIT book, but there is a new resource available too. (Troubleshooting Campus Networks. :-) Remote Access: This didn't seem to have changed. The Cisco Press book edited by Catherine Pacquet is still an excellent resource. Yes, you may encounter BCRAN questions from last millennium's technologies and products. Switching: This had changed. So know the topics listed for the latest version. I'm not sure what you should study. I guess the official BCMSN book? I studied with Cisco LAN Switching, by Clark and Hamilton, which is excellent, but I still couldn't answer a lot of the questions. I suspect you need a lesser book so you know all Cisco's latest misconceptions about LAN technologies. ;-) For the switching exam, know your stuff because some of the questions are unanswerable by anyone with a logical brain. You'll get things like: Which 3 statements are true? IEEE 802.3 FDDI SONET Gigabit Ethernet Notice, the answers aren't statements! ARGH. Finally a word about CertificationZone. I have written troubleshooting guides for them but am no longer compensated by them, so I hope you won't think this is biased. Their papers were extremely helpful. Also they have practice exams for BSCI, Support, BCRAN, and Switching. The practice exams are very helpful, with one exception: SWITCHING! (The bane of my existence.) Their switching exam covers too many topics that aren't on the current exam. Well, that's all for now. I'm just happy to be certifiable for another 3 years. ___ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=66644&t=66644 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: NT domain access after connecting through VPN [7:66618]
>From my experiences in deploying both pix and the 3000 series concentrators, the question of 'seamless' authentication or access to network resources once connected to the vpn is always an issue. To get around this I have seen various methods utilized, each of which has catches and possibly user's computers altered which throws a wrench into things if we're talking home users PC's etc. Argh. The first method, is what you have already mentioned which is to have the cisco client load before the windows login prompt and establish the vpn, and then use the regular domain username and password, which will provide full resource authentication based on the NT account rights. I have been successful with this method and have found it to work quite reliably. The other methods I have used is kind of clunky in my own opinion which is a) have the users authenticate to the vpn, then distribute a batch file login script with the 'user' switch in it, which when executed will prompt the user for a password once, and then cache the authenticaiton credentials for future resource requests or b) Create a matching profile on the local machine that matches the username/password created in the NT database which will allow the seamleass authentication affect. As you can see, a & b are not scalable and require more configuration of the user's machine and ability on the user's part. I apologize for the long winded reply, and I hope this sheds some light on the topic. I am interested to hear of anyone else's solutions to this problem. Utltimately I think with your specific case, seamless authentication is your only route (ie. using the client boot before startup method) as the domain event logs will not prompt you to authenticate, in which case cached credentials have to be used.

But also many times > your contributions are rather rethorical than practical and at the same > time you seem to draw attention to what your opinion is rather than to > give an educated and objective view backed by any type of real life > examples. First of all, given the subject matter (MPLS), it is most difficult to be giving out real-life examples. The fact is, MPLS is at this time not widely implemented, so therefore few examples abound. Second of all, it is essentially impossible for anybody to make a posting that is not necessarily colored with an opinion, particularly when they are discussing a subjective question. Questions like whether they should study MPLS or what they should do with their future are necessarily going to draw a wide range of opinions. If everybody is supposed to dogmatically answer 'yes' or 'no', then what's the point of even asking the question in the first place? The point is that subjective questions must necessarily elicit subjective answers. People are not robots. Everybody has to call it like they see it. You ask a subjective question, and people should be able to chime in with whatever they think. It's all about freedom of speech. Third of all, Cisconuts and I have taken the discussion offline, and while I don't want to speak for him, I would venture to say that he is quite happy with my responses. So if he's cool, then what exactly is your beef? Fourth of all, I resent the implication that my views are not educated. Be careful when you go around saying stuff like that. I seem to recall a story a few years ago how one particular guy harangued another guy about BGP, essentially saying that he knew nothing about how BGP really worked - only to find out later that the second guy was none other than a certain Tony Li, the father of BGP. Now, don't get me wrong, I'm not saying that I'm Li or anywhere close to him. What I'm saying is that you should watch your fire. >So yes, I'm saying that some times you don't quite stick > to the subject at hand. I don't see how your view on Cisco's curriculum > in re to MPLS can be taken seriously without you putting actual examples > of how you came to that conclusion. Ok, fine, then let's review the CCIP curricula vis-a-vis MPLS, and in particular, let's review what exactly they teach. I know for a fact that they teach primarily LDP and gloss over RSVP-TE. Do you think this is wise? There is no evidence in the industry of a consensus that LDP will automatically win out over RSVP-TE. If you have such evidence, I would like to see it. I doubt that LDP will ever win out simply because you can't do TE with LDP unless you go with CR-LDP which Cisco does not have any plans to support at this time. TE is one of the more important features available within MPLS. The point I'm making is that neglecting RSVP-TE within an MPLS exam seems rather dubious. Second, the last 2-3 modules of that class deal specifically with l3vpn's, with nary a mention of any l2vpn technology whatsoever. Again, why such an emphasis on L3 but no discussion of L2? Much of the most exciting work in MPLSCON is about l2vpn's. Don't get me wrong, L3 is good to know, but a good MPLS class would also get into a discussion of l2. The point I'm making is this. If all you do is follow the official Cisco MPLS class, you will get a warped view of how real-world MPLS is. LDP is not the ultimate no-brainer signalling path for constructing LSP's and MPLS can do far more than just L3VPN's. I'm not telling you not to follow Cisco's curricula. What I'm saying is that you should supplement it with other readings and experience. >Even if the knowledge required for > achieving > Cisco's recognition in re to MPLS was not as advanced as one would hope, > shouldn't we look at positives of the whole process ? Again, it's not a matter of being advanced as it has to do with emphasis. I think that the coursework emphasizes some of the not-so-important things and does not discuss some of the more important things. Also, I don't think it's my job to 'play nice'. If things are not good, then I think people should say that they're not good. Why engage in diplomatic euphemisms? Does it really do anybody any good to dress things up so that they look better than they really are?

Re: A career in MPLS..... [7:66609]
I wonder if Cisco's MPLS class is just dated. It takes a long time to develop and roll out a new class, especially if there's also a Cisco Press book, exam, instructor materials, course binder, instructor training, beta testing, etc. In the early days of MPLS, was there more emphasis on LDP than on RSVP-TE? Were MPLS L3 VPNs around before L2 VPNs? Maybe it's just a matter of "course development latency." Thanks for your insights.

VLAN loop problem [7:66656]
Hi All, I got a problem in the production campus LAN here between VLANs. Please help me out! Below is the scenario: We have VLAN 10 (10.10.x.x) and VLAN 20 (10.20.x.x) subnets. Routing is enable/allowed between the two subnets using MSFC of the 6500. Each subnet has a DHCP server to assign IP address to devices on its subnet. Spanning-tree is enable; however, portfast is turned on on all non-trunking/uplink ports. Recently, devices on VLAN 10 got assigned an IP address of 10.20.x.x , which is from the DHCP on the other scope and also from 10.10.x.x scope, and vice versa. It seems that we a loop somewhere between the 2 subnets but we don't know where. I noticed lots of end users have a little unmanged hub/switch hang off the network jacks in their cubicals and potentially cause loop. Is there any way that we can block the loop on the Cisco switches without visiting cubicals taking those little umanaged hubs/switches? Thanks!

Good one, Jay. I saw that story on Slashdot this morning and raised my eyebrows for a nanosecond or two but was too busy to follow up. The April Fool RFC is a long tradition.

Re: A career in MPLS..... [7:66609]
Ah - MPLS.Yes there are several large carriers with MPLS deployed or in the process of deploying it (equant, global crossing...). Some on their core and some on their layer 2 networks such as ATM (AT&T for example). Others backed away from it but are now looking at it since it's a huge marketing beast that can't be ignored (Sprint for example). Aside from ISP's some large enterprises are using it for things like MPLS enabled VPN's. As to the market for someone that knows MPLS - what I have seen is it's a very specialized and small market right now that is looking for MPLS experience. Mostly due to it still being relatively new in deployments and being relatively small in the number of deployments. I do believe however after saying that - that it never hurts to have a wide background of skills. Imagine if you specialized in Novell and never moved into other areas for example. Novell is a great product but the market for Novell pro's dried up a lot from the good ole days. You would be much less marketable if you didn't also know other things such as Microsoft or Routing or ... I could go into my opinions of the pros and cons of MPLS and where I think it fits - but that's another boring story for later :) www.ccie4u.com On 1 Apr 2003 at 15:47, nrf wrote: > ""Cisco Nuts"" wrote in message > news:[EMAIL PROTECTED] > > Hello group, How does one feel about a career in MPLS...I mean doing MPLS > > as part of your core job day in and out.Is it worth it?

LDP (RFC3036) was standardized before the RSVP-TE extensions (RFC3209). More to the point, LDP is really an outgrowth of TDP, which was the basis for Cisco's old-school tag-switching. Therefore it is indeed true that LDP and its ancestors were around longer. Having said that, let me now say that traffic-engineering is a fundamental basis of modern MPLS implementations and one would be most remiss in dismissing its importance. > > Were MPLS L3 VPNs around before L2 VPNs? Again, yes, RFC2547 has been around for quite awhile now, despite numerous concerns about its implication of BGP scalability. L2VPN's are still in the draft stage. > > Maybe it's just a matter of "course development latency." Thanks for your > insights. I'm not faulting Cisco's educational team. They had to work with what was available at the time, and I understand that. What I'm saying is that it behooves the student to understand where the Cisco curricula is dated, and then adjust accordingly. This is similar to the BCMSN course material which also has problems with dated material. I mean, why emphasize MLS so much when all of Cisco's modern L3 switching gear uses CEF? > > Priscilla > > > nrf wrote: > > > > ""Henry D."" wrote in message > > news:[EMAIL PROTECTED] > > > I don't mean to start any type of argument here, especially > > with someone > > > who obviously has more experience than I do.

Redundant Wan Links [7:66659]
My client would like to reroute traffic for their WAN links. We currently have 3 sites. A T1 line connecting each site and a backup DSL link at all sites Should any of the T1 links go down we would like to have traffic rerouted to the DSL link. How could this be done on the router and is there any additional hardwae we need to purschase?
