2 Wire T1 - HDLC
by wb8foz＠nrk.com 15 May '01

Of course, this whole flame-fest is pointless. T-1 can't be 2-wire. T-1 is a facility. Circa 1962, it *carries* DS-1 format bits, over 2 pairs, with repeaters every 6Kft (except the first is 3Kft from the CO..). {Gee, the exact spacing of 88mH load coils....must be coincidence..} You can get those DS-1 bits (that's what really you want...) delivered over: T-1, HDSL, as part of something bigger, <RFC-1149>, whatever. And 95% of the time, you likely don't care....as long as the bits arrive. Just like the guy downstream does not care if you have a cisco 9000 or a HAL 9000, as long as his service stays up. Can we go back to worrying about things that SHOULD scare all of us, such as MPAA, COPA, RIAA, and CALEA; rather than worrying about the ghostly remains of RabbitNet? -- A host is a host from coast to coast.................wb8foz(a)nrk.com & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433

Among other things, I'm also a SysAdmin. Of course, I have multiple personalities! But, Alex Black isn't one of them. Also note, Andreas Stoller's email addr. Do you actually think I would get any sort of response if I sent an email there? I might as well send it to abuse(a)mhsc.net. He probably uses the same bit-bucket that mhsc.net does (the /dev/null brand).

Look in the O'Reilly "DNS and BIND" book, 3rd ed., page 217. Also, RFC2317. However, I have not yet found a single upstream that even knows how to do it, let alone offers this as a service. They are also not happy that I won't sign control of my domains over to them and that I run my own zone servers. Gee, why don't I hand over my bank accounts while I'm at it? BTW, if you know an ISP that does, I want their contact number. I'm not trying to win any arguments here. If I lose then I win, because I will have found a decent vendor. Also, with my monthly recurring cash on the line, don't you think I've been looking?

Next-hop Reachability on ATM NAPs
by Reid Knuttila 14 May '01

14 May '01

NANOG members, I have a question to the group regarding how best to avoid blackholing routes to peers on an ATM NAP when using route servers. There is a case wherein my peering partner and I both have active PVCs to the route servers, but the PVC between my peering partner and my router is down. Thus, we both see routes from the route server with each other's IP as next-hop, but since our direct PVC is down that next-hop is no good. It'd like a way to automatically and efficiently detect loss of next-hop and discard routes accordingly. Are folks generally using OAM keepalives, and if so, any parameters for OAM interval time and dead/alive count that seem practical? Thanks, -- Reid Knuttila Network Engineer Onvoy

Are you seriously suggesting using PostgreSQL over Oracle, in production? Mind you, I do pgsql too. But, not in high-volume production.

I stand corrected. I checked with our service delivery department, who actually does our SWIPs these days, and they don't do anything larger than a /29 any more either, for the same reason that Hunter doesn't.

After viewing this whole thread and having come from a use-to-be the-great-white-hope "DLEC" I can say that the problem really doesn't lie with the technology but rather with the self deceptions the IPO-happy corporate officers told themselves and their investors about how easy it is to run a carrier and possibly in the outright deceptions of certain "you've got to use our equipment to use our neat little marketing logo" manufacturers. But over all, basic DSL technology has been used for over 15 years by ILECs to provide T1 services over long spans.
