I know from past experience as a transit customer, that I have personally shyed away from ISP's that have restricted me to having their NOC update my ACL. However, I don't really see a reason why ISP's shouldn't implement max-prefixes on their customer sessions; This would not prevent against very small prefix leaks, but would prevent partial and whole routing table leaks that impact many networks. How many of you that currently do not filter your customer BGP sessions have max-prefixes configured? How many of you that currently do not filter your customer BGP sessions and do NOT have max-prefixes configured would be willing to configure the sessions to support this? Joe

Sorry about that - apparently there was a Broadwing fiber cut 1 mile west of Dallas that affected Fort Worth and Houston. All is back up now (after doing my share of freaking out!).

Donkey Balls

Hey, In my fraternity we have a tradition of sending "donkey balls" messages to people who leave their email accounts open on other people's machines. Anyhow, just a friendly "Hi, you suck donkey balls!" note from your friend Emily. :-D E

Well, it was one of ALGX downstreams leaking to them. Shame on them for not filtering their customer properly. How many times do we have to learn this lesson? I noticed this right as it happened ( or rather our NOC did ) as we dropped our ALGX peering sessions. We sent an email to their NOC and the downstream customer letting them know what happened. The downstream customer responded right away. The ALGX noc email bounced back to me. -Chris -- \\\|||/// \ StarNet Inc. \ Chris Parker \ ~ ~ / \ WX *is* Wireless! \ Director, Engineering | @ @ | \ http://www.starnetwx.net \ (847) 963-0116 oOo---(_)---oOo--\------------------------------------------------------ \ Wholesale Internet Services - http://www.megapop.net

For one thing, one can just pose the question the other way around (what functionality does VLAN give you that does not exist in Frame Relay (with closed user groups + LMI; that has been around for quite some time)). >What is the current max speed of frame relay in any common vendor >implementation (I'm talking routers here). > >-- What is current changes. Same technology can be applied to both Ethernet and Frame Relay encapsulation. Ability to bring more traffic to the exchange in itself may not be useful if there is no ability to switch it. >Mikael Abrahamsson email: swmike(a)swm.pp.se > nenad

LISA: sysadmin conference, take 16.
by Gerald 15 Aug '02

15 Aug '02

I got a chance to go to last years LISA for the first time. I had been trying to go for 3 yrs. I have changed companies since then and am now working for a lot smaller company that can't afford to pay for these kinds of things which brings me to my question(s) for the list: How can an individual that has passed beyond "student" status afford the costs of LISA? I'm already a Usenix member in good standing, but even at those rates, to attend the whole week is quite expensive for an individual. (It's about equal to my rent here in NYC which isn't cheap) Just wondering if any nanogers have tried to justify this cost to themselves if they have had to pay for it, or if there's a hidden "my-company-and-I-can't-afford-that-much" button/link on their web page. TIA for input, and those that feel it's not on topic can reply to me off list. G - How are ya? Never been better, ... Just once I'd like to be better.
