IPv6 IGP
by Daniel Corbe 09 Apr '04

09 Apr '04

I'm trying to decide which IGP I want to go with for our IPv6 deployment. Anyone have any experiences with OSPF for IPv6 in the IOS 12.3 mainline? Is it stable enough? I'm contemplating iBGP over OSPF..

It seems they have low-latency links to everyone and everywhere in .eu Keep in mind though that both Telia and Tiscali refuse to peer with smaller providers on the European exchanges. It's probably a good idea to check if the provider you want to use has an open peering policy as well as a large network if you really want the best performance. For example, http://www.ams-ix.net/connected/index.html lists all members of the Amsterdam Internet Exchange, and their peering policy. Mike.

Any good Wave Boxes to do this?
by Deepak Jain 09 Apr '04

09 Apr '04

I have seen boxes from MRV and others that will do 2GE into an OC48. I really feel bad about "wasting" that 500mb/s on essentially an IP application, but can't really justify putting OC48 ports into a catalyst 6500 of this application. Likewise, uplinking to a GSR just to get cheaper OC48 ports doesn't make sense when you count the cost of the GE ports. Is there a good box out there that will say take 2xOC48 and give me 5 GEs? Thanks, Deepak

That's not the way I see this at all. I look at it as a good complement to anti-spoofing filters as part of defense in depth, in case said filters get SNAFUed. My primary line of defense will remain ACLs. Michel.

Looking for opinions and experience on Tiscali IP network performance within Europe and out of Europe i.e. North America on the whole.. I have heard mixed reports, but am looking for information from those with first-hand experience either on transit or peering level. Would they be classed in top-three performing networks in Europe (recent bandx report gave them #1 spot)? If not what are you recommendations on reaching the largest amount of eyeballs on a very stable network primarily in Europe. Thanks in advance for your time. Regards, Shazad

OT: Determining toll free # ownership
by Jon R. Kibler 07 Apr '04

07 Apr '04

Hi, I know this is somewhat off topic, but I am hoping someone here has previously dealt with this problem and has an answer. For some reason, the access telephone number for our "internal use only" dial-up modem pool -- which also happens to connect to our fax server -- has gotten on several fax spammers telephone list as being a fax telephone number. We have captured several dozen faxes sent through that number over the past few days, and they all have 'enter your number here to delete' toll free numbers on them and we would like to find out the telco that owns those blocks of 800# so we can complain. I have heard that there is a number that you can call, enter a telephone number -- such as the toll free number we want to complain about -- and it will tell you the telco that owns that phone number. Does anyone know what that number is? Thanks! Jon Kibler -- Jon R. Kibler Chief Technical Officer A.S.E.T., Inc.
