Hi,
I am using cisco 29xx and 3xxx switches. The problem with FEC is that I have
no way to use dst-ip hashing as the load balancing option on these two
switches, and that would cause biased utilization on a certain link only,
i.e. impossible to utilize 2*100=200Mbps.
and...if I were really to use FEC as the solution, I will need to get some
much expensive switches from cisco, which is quite unaffordable and imho
unnecessary in fact...

hello
I do not think you should mess a lot with interdomain routing here. Such a
scenario (multiple uplinks from the same ISP) IMHO is better be solved on
the layer 2.
What you need is some technology that utilizes two Ethernet ports at once.
About a week or two ago on this list was discussed similar setup using Cisco
technology. Search for subject "ng_fec and Cisco 2931". I f your ISP is
using the switch/router that supports FEC, you could do this trick. Also
most 3com intelligent switches support aggregating links via multiple
100Mbit channels. If you have put 3com equipment on both sides of your
internet connection you'll can get what you want.
Hope that helps.
BTW the first and best thing to do is to ask such question to your ISP.
Nick

Hi,
The main problem is that I have no idea at all how should I setup
everything..and what do I need from my ISP......I just know it was possible,
but I can't recall the details inside, and a simple google did not return
anything helpful to me.
I agree with you that fbsd (or any other linux) is much better than cisco in
terms of stability. The cisco routers at my site are crashing like cron jobs
while the fbsd boxes usually have long uptimes. :)
off topic: I used to be a network admin some time ago, but no longer true
now....and unfortunately, in the past I had only very few chances to deal
with interdomain routing, mainly in lab.
I'm afraid I have forgotten everything by now :(
