I have a question... I am currently expanding our network to accommodate a T1 to the Internet and a 512K frame connection to our WAN.. I need to purchase a router and spoke to several vendors. I have heard conflicting stories regarding the model of Cisco router I should get. One vendor <vendor a> tells me that I should get a 2620 with 2 Wan Ports and the other vendor <vendor b> is telling me that I might compromise my security by using one router for WAN and Internet connections. Their suggesting that I get 2 routers one for my Wan and another for the Internet connection... Vendor B is telling me that it would be possible to enter our wan without touching our firewall should someone be able to hack into our IOS on the router... I decided to go the experts... I would appreciate any helpful suggestions. Thanks... -Gerry

I should have provided more details in my message. I am CC'ing this response to the group so that these details are clear. I have already received several useful responses and will issue a summary when the message frequency drops. We will be splitting T1's into 128's, 256's, ... (not 56Kb lines because the lower bandwidth lines have 56Kb local loops). The T1 lines would typically be split into a maximum of eight various speed ports (128-512, occasionally 56, but not typically). I am assuming that products exist to split directly into a 256Kb without requiring that multiple 56's to be bundled, but this may not be the case (I would appreciate clarification on this point). We may subsequently use it for 56K lines, so a chassis that supports both 8-way and 24-way cards is helpful. Approximately 50 T1's are currently candidates for splitting to lower bandwidth. Our preference is to use multiple small capacity DACS rather than larger 'megaDACs' to minimize the impact of a chassis failure. We will have at least one unpopulated hot spare in each location.

Query for NANOG: Want a Peering BOF?
by William B. Norton 22 Sep '99

22 Sep '99

Hi all - Before proposing a Peering BOF I'd like to get a sense of the community interest, so here is what I was thinking... Peering BOF Description ----------------------- The idea would be to have a BOF for those who are interested in establishing peering relationships, to find out who each other is, and have a light agenda focused on one or two short peering-related issues. In this forum we would pass a hat around to get everyones business cards and then e-mail out to those folks an Excel spreadsheet with everyones contact information. The hope is that this would help facilitate peering in the 'net. Agenda ------ I can contribute to the agenda an overview of a draft I just finished (with the help of a bunch of you) called "The Peering Decision Tree" that describes in rough terms the process the ISPs I spoke with go through to determine with who and with which method to peer. So: ------ Please send me private e-mail me if a) You think this is a good idea and you would participate in the BOF, or b) You have an agenda item you'd like to contribute, or c) This is the worst idea Curtis has ever heard. Thanks! Bill Note: From the looks of the agenda there may not be time to do this BOF at the Montreal NANOG so if there is interest we may have wait til NANOG 18...Let's first see if there is interest... ---------------------------------------------------------------- William B.

Rochelle Park and North Carolina
by Sean Donelan 21 Sep '99

Bell Atlantic indicates 95%-99% of the telephone service should be restored from their New Jersey Rochelle Park office by 9am Monday morning. Bell Atlantic and AT&T Wireless, who also has equipment in the same building, have put updates on their web sites and issued media releases about their progress. Apparently in the past BA had used a half-dozen pumps to keep the water out of the building, but residents in the area complained that practice made the flooding worse in their houses, so they weren't used this time. At its peak, 99 Bell Atlantic reported central offices on backup power. Something to watch out for the next few days in North Carolina. Due to road damage from flooding, diesel deliveries are iffy in much of eastern North Carolina. Unless power is restored, some facility generators may run dry.

Perhaps. but even the best layed plans can get scuttled. And in this case 3 to 4 feet would not have been enough. Many ATM cash machines are off-line all over the country because EDS's data center in New Jersey went down due to power failures and flooding. If there was a data center that met the description of a "bunker" that was it.

IS-IS reference
by Jack Crowder 18 Sep '99

18 Sep '99

I was wondering if I could talk with someone who has recently implemented IS-IS. I'm attempting to move a small NSP away from static routing and based on their topology - OSPF would have to be configured all in Area 0. Since the technology provided by this NSP to their customers will include multicast services (video specifically), I thought that I should consider IS-IS while the slate is relatively clean. If there is someone who has implemented this routing on their network that I could ask a few questions of (practical experience), I would appreciate it. Jack Crowder monterey(a)spies.com

If I recall, during hurricane Hugo a Sprint CO flooded. They kept the water from coming in the doors, but didn't have a snorkal for the generator. Although its great fun to discuss different disasters which can hit buildings, a fundamental principle is a you can't protect a single building, even a bunker, from everything.
