Dynamic routing on firewalls.
by David Jansen 09 Feb '15

09 Feb '15

Hi, We have used dynamic routing on firewall in the old days. We did experience several severe outages due to this setup (OSPF en Cisco). As you will understand i’m not eager to go back to this solution but I am curious about your point of views. Is it advisory to so these days? Kind regards, David

Provider to Blend with Level3
by Colton Conor 09 Feb '15

09 Feb '15

We have a network that is single homed with Level3 at this time in Dallas. They already have BGP and their own ASN and IP setup. Who would you recommend for a second provider in Dallas to blend with Level3? Assuming Level3 and this other provider would be the only two in the blend for a long time to come? Client was talking to TWT, but now that they are being bought by Level3 that doesn't make much sense.

scaling linux-based router hardware recommendations
by micah anderson 08 Feb '15

08 Feb '15

Hi, I know that specially programmed ASICs on dedicated hardware like Cisco, Juniper, etc. are going to always outperform a general purpose server running gnu/linux, *bsd... but I find the idea of trying to use proprietary, NSA-backdoored devices difficult to accept, especially when I don't have the budget for it. I've noticed that even with a relatively modern system (supermicro with a 4 core 1265LV2 CPU, with a 9MB cache, Intel E1G44HTBLK Server adapters, and 16gig of ram, you still tend to get high percentage of time working on softirqs on all the CPUs when pps reaches somewhere around 60-70k, and the traffic approaching 600-900mbit/sec (during a DDoS, such hardware cannot typically cope). It seems like finding hardware more optimized for very high packet per second counts would be a good thing to do. I just have no idea what is out there that could meet these goals. I'm unsure if faster CPUs, or more CPUs is really the problem, or networking cards, or just plain old fashioned tuning. Any ideas or suggestions would be welcome! micah

Metaswitch ax1000 as a RR
by David Bass 08 Feb '15

08 Feb '15

I have a client looking to implement x86 based route reflectors, and was looking at the ax1000. I'm wondering if anyone has implemented it yet, and what your experience has been? Any other alternatives would also be appreciated. This customer does standard L3 VPNs, and VPLS services so the software has to support that. Thanks!

Low cost WDM gear
by Mike Hammett 07 Feb '15

07 Feb '15

I know there are various Asian vendors for low cost (less than $500) muxes to throw 16 or however many colors onto a strand. However, they don't work so well when you don't control the optics used on both sides (therefore must use standard wavelengths), obviously only do a handful of channels and have a distance limitation. What solutions are out there that don't cost an arm and a leg? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com

Point taken on the specs.. Still doesn't excuse poor customer service and tech support. I never expect to be told that no refund will be issued when I am dissatisfied with the product. A request for RMA because something is not working as expected should not have to be escalated to the President of the company. Other than that I am sure FiberStore is a great company :-) On Feb 07, 2015, at 01:17 PM, Faisal Imtiaz <faisal(a)snappytelecom.net> wrote: My point is...... ...
