ATM SVCs/Signalling
Good morning, I'm working on a project that requires the use of ATM SVCs through a large PNNI cloud. My equipment sits on the edges of the cloud. It appears that static NSAP routes configured on one of the upstream edge switches is being intermittently withdrawn (or blocked). Are there any operators on the list who have experienced this type of problem or could point me in the right direction as to what could cause this to happen? Thank you, -- Mark Borchers Infinite Global Infrastructures, LLC
Re: ATM SVCs/Signalling
Mark, 1. What manufacturer of the devices and what model are the edge and then the network device you are connecting to? 2. What version and revision of UNI (3.1,4.0) is your edge device using? UNI 3.0 is PVC, UNI 3.1 is original SVC support, UNI 4.0, 4.1 if it is out yet is more advnaced SVC. PNNI 0 did not support SVC so that would need to be at least PNNI 1.0 as I remember. 3. What version of NNI / UNI are the Network devices using? 4. What error code return are you getting? 5. Are your NSAPI addresses statis or dynamic and do you have dynamic TEI registration set or are they statucally assigned. If your NSAPI and TEI are dynamic and your keep alives are not set rigth perodically you will drop unregister the NSAPI / TEI amd it will have to be reregistered again and during this time the route would be dropped.

RE: ATM SVCs/Signalling
Will go off list with any subsquent QA, but here is the further detail on the architecture: 1. What manufacturer of the devices and what model are the edge and then the network device you are connecting to? Using Marconi 200ASX connecting to transit provider's Fore/Marconi switch (don't know their model). 2. What version and revision of UNI (3.1,4.0) is your edge device using? UNI 3.0 is PVC, UNI 3.1 is original SVC support, UNI 4.0, 4.1 if it is out yet is more advnaced SVC. PNNI 0 did not support SVC so that would need to be at least PNNI 1.0 as I remember. UNI 3.1 3. What version of NNI / UNI are the Network devices using? I'm signalling IISP to the far end. Our network is very simple and IISP meets the requirements. Besides, I don't know PNNI and the project schedule probably doesn't permit time to learn it. 4. What error code return are you getting? I've seen both UNI error code 3 and 35. 5. Are your NSAPI addresses statis or dynamic and do you have dynamic TEI registration set or are they statucally assigned. Static. If by dynamic TEI registration, you mean ILMI, we're configuring ESI on the routers and registering with the ASX by ILMI. Does that answer the question properly? If your NSAPI and TEI are dynamic and your keep alives are not set rigth perodically you will drop unregister the NSAPI / TEI amd it will have to be reregistered again and during this time the route would be dropped.

RE: Problems with ATT
Personally, I would have preferred that the caution showed itself prior to rolling out something that doesnt support ICMP sufficiently. Caution at that stage would have been most appropriate and most welcome. :-) Can you elaborate on which vendor and what specific issue you are dealing with? That might alleviate some head scratching as we (any affected parties) all await the vendor fix. I've got an HTTPS application that used to work great when InterNAP was giving us a path from Dallas to Atlanta over UUNET's network. But when we moved to Plano, InterNAP started pushing us over ATT. The RTT is fantastic to our destination which is why I suppose we have that route but I suspect that it's not simply ICMP that's getting dropped on ATT's network. Sorry, I've heard it from mutliple sources that it's just ICMP that's getting deprioritized/dropped but I'm skeptical. I've lost a little faith in the InterNAP secret sauce. :( -Original Message- From: Truman, Michelle, SALES [mailto:[EMAIL PROTECTED] Sent: Friday, March 21, 2003 2:01 AM To: Mohammed Al Sukkar Cc: [EMAIL PROTECTED] Subject: RE: Problems with ATT Mohammed, ATT is working with the vendor on a fix.

Re: APNIC returning 223/8 to IANA
I think your getting confused? The restriction is on subnets using classful addresses, you shouldnt use all zeros and all ones subnet for a given subnetted classful network. In the examples below, 192.0.0.0 and 192.0.255.0 are valid Class C networks.. however if you then go classless and presumably enable ip subnet-zero on your cisco routers as well then no such restrictions exist including on 1.0.0.0/24 or 223.255.255.255.0/24. On Thu, 20 Mar 2003 [EMAIL PROTECTED] wrote: Its not quite that simple folks. The reason this particular block is reserved has some real technical merit, while the 69/8 muddle is strictly due to ISP negligence. RFC 3330 got it wrong. Anyone remember the Martian List from the 1970-1990's? Trying to use the all-ones or all-zeros network for real traffic is not possible. Pre CIDR it was not possible to use 192.0.0.0/24 or 192.0.255.0/24. (the same was true on -every- network boundary) With CIDR, those boundaries moved to 1.0.0.0/24 and 223.255.255.0/24 e.g. only two reservered blocks instead of hundreds. Simply having someonechange a DB entry or create an RFC will not affect the installed silicon base. Won't work. APNIC is on the moral highground here. They received damaged goods without notification. IANA needs better technical clue. --bill Unless I'm mistaken, there is no technical issue with using the All-0's or All-1's classful networks. In fact, several of those networks are in use. 0.0.0.0/8 this network (all-zeros A) 127.0.0.0/8 loopback network (all-ones A) 128.0.0.0/16reserved but unused (all-zeros B) 191.255.0.0/16 reserved but unused (all-ones B) 192.0.0.0/24reserved but unused (all-zeros C) 223.255.255.0/24reserved but unused (all-ones C) As with 0/8 and 127/8, the other 4 networks could certainly be designated for some use, including normal end-users. This type of end-user usage would even continue to work with old classful gear. Nope, we weren't talking about subnets, but the classful networks themselves. Would you agree, as I've suggested, that there is no inherent technical limitation to using 223.255.255.0/24?

I've been asking customers to use trace only for path detail and to use end to end ping for any performance data.=20 Yes, the core is MPLS enabled. Diffserv acted on only at the edges though.=20 Michelle It could certainly be customers who have broken themselves. I've heard lots of stories about people who do PMTUD but simultaneously filter ICMP Can't Frag messages. As soon as the Path MTU drops below whatever their local box is (usually 1500) they break although due to their own screwed up config. Since MPLS adds additional overhead, dropping the MTU, I'ld seriously consider this as a possible reason. Speaking very generally and not about any one specific network, this is likely to not be the issue. MPLS leads to problems on Ethernet, but I've seen no problems in anything other than Eth/FE. GigE and POS haven't had the same issue; for one, default POS MTU is ~4k, which is more than enough to hold packets from hosts that assume 576 or 1500, and PMTU over an MPLS network takes the MPLS label stack size into account when doing discovery. Also, some implementations have framers that can accept a packet that's actually MTU+(N*4), where N is typically no more than 4, and more likely 2. And I think I can say without breaking any confidentially agreements that ATT's backbone Probably Isn't (nudge nudge wink wink) made up of scads and scads of 10/100Mb links everywhere. :) All you need is 1 1500-byte MTU L2 network to have a customer with a broken PMTU-D setup experience a problem. Even if you have lots of GigE links, you often have some old gear connected to said switch which doesn't do JumboFrames, requiring that you preserve the LCD. As someone else mentioned earlier, if there was a per-neighbor MTU this would resolve a huge part of the problem of transitioning to jumboframes, since it would permit staged upgrades rather than forklift all-or-nothing upgrades (always something to be avoided if possible). I can say from experience that these broken customers _are_ out there and generally refuse to admit/accept that doing PMTU-D while simultaneously filtering all ICMP is why they are broken. It isn't an MPLS problem, any encapsulation which reduces the effective MTU to below 1500 would tickle the customer's config bug. These days, however, few network operators are using additional encapsulations other than MPLS. Also, it isn't an ethernet problem, since the point at which the customer breaks is solely determined by their local MTU. As such, it just happens that most customers use ethernet as their lan media, and MTUs of less than 1500 are extremely rare (hiding their config problem). The biggest problem you can have with MPLS is if you have customers who are connected at 4k or 9k or what have you, and who don't do PMTUD; I've not seen this come up as a real operational issue. I fail to see how that would be a problem, except for the fragmentation issue. While fragmentation is a performance issue, it doesn't lead to lack of reachability. Whereas doing PMTU-D and simultaneously filtering the bits that actually make it work, does lead to reachability problems. .02 eric

I have a powerbook, and I use the USB serial adapter from Keyspan. Should work great for a PC; it's the only one that will work for OS X that I know of. While there isn't much in the way of decent terminal emulators in OS X, there are two other ways to use the keyspan. For the bsd geeks (like most on this list, I would assume), it creates a POSIX device in /dev, so you can use your favorite command line and X-windows apps (for those who haven't switched, apple's support for X-windows is damn nice). And for those with Virtual PC, the keyspan adapter can be shared with the emaulated PC, and you can use SecureCRT, the best terminal emulator ever.

Greetings all, Anyone have an SBCIS (AS7132) contact with DNS clue? I'm being told it's company policy that they list their nameservers as authoritative for reverse DNS on space assigned from their netblocks. IOW, they delegate by creating NS RRs that point to the correct NSes _and_ NS RRs pointing to their own. It gets better. Like all good authoritative NSes, their NSes disallow recursive processing. Is it truly company policy to screw up reverse DNS for downstreams who run their own? Wanted: AS7132 contact who understands the concept of lame servers, why they are bad, and is willing and able to help do something about it.

Re: OT: need SBCIS (7132) contact with DNS clue
Eddy, If you have an xDSL line with static IP's on a /27, then PBI/SBC will setup the DNS as follows. In this example W is the base IP of the network (ie: 0,8,16,24,32,40,48, etc.) and (W+n) should just be a number and not have parentheses or a plus! PCI/SBC will add the following to their zone files... W.X.Y.Z.in-addr.arpa. IN NS your-nameservers W.X.Y.Z.in-addr.arpa. IN NS your-nameservers W.X.Y.Z.in-addr.arpa. IN NS your-nameservers In my case they did NOT list PBI/SBC as a NS for that specific zone, hence it always comes over to my boxes. Then PBI/SBC will add this in their zone files... (W+0).X.Y.Z.in-addr.arpa. IN CNAME (W+0).W.X.Y.Z.in-addr.arpa. (W+1).X.Y.Z.in-addr.arpa. IN CNAME (W+1).W.X.Y.Z.in-addr.arpa. (W+2).X.Y.Z.in-addr.arpa. IN CNAME (W+2).W.X.Y.Z.in-addr.arpa. (W+3).X.Y.Z.in-addr.arpa. IN CNAME (W+3).W.X.Y.Z.in-addr.arpa. (W+4).X.Y.Z.in-addr.arpa. IN CNAME (W+4).W.X.Y.Z.in-addr.arpa. (W+5).X.Y.Z.in-addr.arpa. IN CNAME (W+5).W.X.Y.Z.in-addr.arpa. (W+6).X.Y.Z.in-addr.arpa. IN CNAME (W+6).W.X.Y.Z.in-addr.arpa. PBI/SBC did not do the W+7 entry for me but they did do the W+0 entry. :-) That all said, you just need to add one zone W.X.Y.Z.in-addr.arpa on your side. Why is this confusing? Because if you got the same email as I did... they didn't even come close to explaining it this way and hence why your worried about the recurse on the NS's.

Re: (possible Flame bait) Backbone Building vs Transit purchasing
*IS* there a common sense number or an equation (better) anyone has worked out to figure whether building a backbone (national/international) to peering points (i.e. extending an existing, operational service network) to improve/add peering vs continuing to buy transit? If you are assuming that this is not about performance then surely this is a very simple thing to work out? Cost of transit T = cost of transit/committed Mbs Cost of peering P = (cost of: circuits+routers+colo+nap)/Mbs of actual traffic If PT go and push your network out to the peering point it will save you money. Now.. at present your problem is that T is very low, and certainly lower than P unless you are moving quite a lot of traffic.. 1Gb is a lot of traffic, so all you need to do is to figure out the costs in getting to a NAP and how much traffic you can shift.

This is very much a moving target as various items (circuits, ports, ip bandwidth) get priced at rates well above over below cost depending on who has how many of them. That said, in the long term, for anyone of size (which I'll define a a few gigs of traffic) I don't think there is a significant economic difference between the two options. This is assuming each option is executed well, with good planning and financial sense. One will be cheaper than the other from time to time, but there will be no clear winner. This means it comes back to a more basic business decision, do you want to be an ISP? Even if the costs are the same for either option a company may be better off just buying bandwidth because building a network is not at the core. On the other side, you might be trying to sell to people who require you to have a network to be taken seriously. At the end of the day my assumption that both options are executed well is the most often violated, and a prime cause is that it was not in a companies core interest. -- Leo Bicknell - [EMAIL PROTECTED] - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - [EMAIL PROTECTED], www.tmbg.org pgp0.pgp Description: PGP signature

Re: Iraqi Internet communications still working 3/21/03
If you want to check your memory, all you need to do is contact the leading registries setting up the (new) ccNSO (of ICANN). There was a liaison from ICANN, I met him at the Montevideo and MdR meetings in '01. The short answer is, it is fucked, indepedent of any flag waving by anyone. It differs only in detail from the general fucked-ness of the re-purposed ccTLDs only in the remarkable worthlessness of the sponsor and operator. So you need to write to Saddam to get your .iq registry working, you might want to hold that thought a few days.. There really is no barrier to entry, is there?

(possible Flame bait) Backbone Building vs Transit purchasing
Notice, I didn't call this Peering vs Transit. I don't want to get into that discussion. :) Over the years, as economics have moved around and such, the question of whether its *profitable* to build a backbone and peer-off most or all traffic vs buying transit for all or some destinations has moved around. Some of the factors are economic, some have to do with onerous or non-existant peering possibilities with one or more networks. *IS* there a common sense number or an equation (better) anyone has worked out to figure whether building a backbone (national/international) to peering points (i.e. extending an existing, operational service network) to improve/add peering vs continuing to buy transit? I was in a discussion about this fairly recently, and I can imagine a number of people have started asking the same questions. To be fair, and hopefully eliminate any religious issues. Let's assume 1) The network-in-question's traffic is balanced [1:1 push/pull] -- I know, we are talking theoretical here. 2) That transit implies a few good networks, with redundancy and fault-tolerance. More specifically, it is not assumed that peering or transit has any net-effect on the customer base because 1) if peering is insufficient, some transit will remain, and 2) if some transit provider is behaving poorly, there is another transit provider available to shift traffic to. I hope this is a reasonable groundwork for a discussion. :) If you want to shoot out numbers (privately) I am fine with that. Let's start the bidding at 1Gb/s sustained. :) Deepak Jain AiNET
