Experience with Larscom NetEdge 85M's
by Jon Stanley 28 Mar '01

28 Mar '01

Do any of you have any experience with troubleshooting unacceptable amounts of latency and packet loss on an Edge 85? Everything looks cool, the DS3 circuit going into is clean, it's not oversubscribed, but the latency and (mainly) packet loss continue. I am at a complete loss as to what to do with this. The packet loss appears to be consistent, however running an mtr at this time is telling me that it's not there. I know from looking with my own two eyes that it was there and worse than ever several hours ago, but it seems to have calmed down now. Any suggestions as to where to go with these things when conventional methods of troubleshooting (including moving the customer to a router closer to the NetEdge) seem to have failed me? 11. xxx.xxx.xxx 2% 594 601 54 42 61 140 Thanks in advance, Jon

RE: MBone access

One of the things that appears to be a major impediment to large-scale deployment is the lack of SA transitivity, which is limited by MSDP's RPF rules. Therefore, the Internet needs a dense mesh of MSDP peerings to allow any-to-any connectivity. As of now, this is not the case. SSM will fix this. regards, chris > > Dear Jared; > > I could do this at NANOG 22 if there was any interest.

Roaring Penguin - Re: PPPoE server software?
by Karl 27 Mar '01

27 Mar '01

Hi Matt, I recalled reading a PPPoE thread on a list a few months ago, so I grepped around and found something on the Mid-Atlantic LUG archives: http://boudicca.tux.org/mhonarc/ma-linux/2000/2000-Oct/msg00229.html At that page, Billy Ball breifly sketches out how you can set up PPPoE with tools from roaring penguin: http://www.roaringpenguin.com/pppoe/ If you can't find everything you were looking for on the roaring penguin page, and msg00229, you might find tweaks in the PPPoE threads here: http://boudicca.tux.org/mhonarc/ma-linux/2000/2000-Oct/index.html I hope the two first URLs give you the PPPoE server leads you were looking for. -Karl PS- sorry if you got this twice.

Of course, many commercial providers consider this highly confidential data and don't share it, assuming they reliably collect it at all. The last commercial provider I saw with any public traffic analysis was ANS. The academic folks have bits and pieces from various networks, but as I suspect you know, it comes and goes. > Netflow data from various sources is proving to be the > most useful, but I need more views.

A number of the intrusdion detection/anti-DDOS vendors may have probes located where they can collect some of this information. And depending on the permision of the customers' the exchange point operators could assist.

BGP Community Attribute Support
by Joe Abley 27 Mar '01

27 Mar '01

Quick poll: does any operator here currently use a router which does not support setting BGP community attributes, does not permit community attributes to be matched exactly when doing ingress/egress route filtering, or does not permit wildcard matches on the last two octets (e.g. "permit 1234:*")? If any of those statements apply to a BGP implementation you have used, could you let me know? Off-list is fine. I can summarise the results if there is interest. Joe

Does anyone using verizon paging service via digital celphone know the number for their modems to send pages. Their sales people want use to use email, what's new, but as you know we need pages when the network is down, not up. Thanks, -Roy

SWM ISO empirical operational data...
by Barrows, Jeff 27 Mar '01

27 Mar '01

smart-operator-folk - I am trying to determine the top-500ish source and destination ASes on the Net today, as measured by the aggregate amount of either ingress or egress traffic. Ideally, I'd have data that was granular enough to be broken down by geographical regions as well. There just isn't useful public data out there that is extensive enough, relevant, or complete. There are lists of "top 50 web sites in the UK", "top 10 most popular sites", and "15 top financial sites", and such, but I couldn't find anything useful that was based on true traffic analysis, or wasn't skewed by incomplete views. Netflow data from various sources is proving to be the most useful, but I need more views. If anyone has any [Netflow or Netflow-like] top-speaker information that they would be willing to share, I'd very much appreciate it-- please drop me a note offline. Also, if you currently operate a network or site that is a major source of traffic, (audio|video streaming, file sharing, software distribution, etc.) and wouldn't mind taking some time to chat with me about your traffic characteristics, I'd appreciate it-- please drop me a note offline. As a last note, [for those international folks following this NA list] I am very interested in your views on the makeup of your traffic to content providers in the U.S., as it compares to content traffic in your own region. ...again, drop me a note offline. Thanks all, - jsb

Mbone access
by Eddie Parra 27 Mar '01

27 Mar '01

Anyone, I am not very familiar with Multicasting technologies, but how can I get access to the Mbone? My DSL provider does not allow Mbone access. Is there anyway I can get a DVMRP tunnel to my Cisco 2611 router at home from someone? I have a static IP. Please let me know! Thanks! -Eddie

Sprint hosed...routing breakdown in Chicago

Traceroutes to lots of destinations (MSN is the one we're getting the most complaints about) die like this. I've got an open ticket with Sprint, but due to their support people playing telephone, the ticket description has degraded into meaningless garbage and I got a voice mail back from their NOC saying they don't understand what our problem is. Meanwhile, I'm sitting here on permenant hold trying to get to talk to someone with a clue in their NOC. traceroute to 206.253.194.65 (206.253.194.65), 30 hops max, 38 byte packets 1 border1-fast0-0.Gainesville.atlantic.net (209.208.0.1) 2.237 ms 1.878 ms 1.109 ms 2 border1-s1-0-2-0.orldflwcom.atlantic.net (209.208.2.105) 22.004 ms orldflwcom-br-1-s1-0-5-0 (209.208.2.217) 20.816 ms border1-s1-0-2-0.orldflwcom.atlantic.net (209.208.2.105) 27.330 ms 3 sl-gw8-orl-3-0-TS11.sprintlink.net (144.232.154.21) 16.851 ms 31.717 ms 17.374 ms 4 sl-bb21-orl-0-0.sprintlink.net (144.232.2.233) 17.299 ms 15.614 ms 15.876 ms 5 144.232.18.201 (144.232.18.201) 38.620 ms 37.844 ms 30.519 ms 6 sl-bb20-atl-15-0.sprintlink.net (144.232.12.145) 30.850 ms 33.735 ms 23.784 ms 7 sl-bb20-atl-10-0.sprintlink.net (144.232.8.134) 41.988 ms 42.959 ms 38.364 ms 8 sl-bb22-chi-15-0.sprintlink.net (144.232.26.49) 38.592 ms 38.411 ms 39.822 ms 9 * * * 10 *Icmp checksum is wrong *Icmp checksum is wrong * 11 * -- ---------------------------------------------------------------------- Jon Lewis *jlewis(a)lewis.org*| I route System Administrator | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
