My system specifications is as below: -

Intel Pentium 4 2.4GHz
1024MB DDR RAM

eth1 and eth2 is National Semiconductor
eth3 and eth4 is Realtek 8139
eth5 and eth6 is Via-Rhine

Hi all,

I have one bridge system (used for controlling bandwidth) connected to three different DSL ISP provider. I have the following setup below: -

+-------------+
|   br0             |
|   -> eth1       | -> DSL_1
|   -> eth2       |
+-------------+
|   br1             |
|   -> eth3       | -> DSL_2
|   -> eth4       |
+-------------+
|   br2             |
|   -> eth5       | -> DSL_3
|   -> eth6       |
+-------------+

br0 has eth1 and eth2; br0 has no ip address

br1 has eth3 and eth4; br0 has no ip address

br2 has eth5 and eth6; br0 has no ip address

The traffic of DSL_1 ISP will pass thru br0. The traffic of DSL_2 ISP will pass thru br1. The traffic of DSL_3 ISP will pass thru br2.

I have a question. Is it ok I do it as above in 1 system with 3 bridges or separate it to 3 system with each system have their own bridge?

One system with three bridges will work fine. The only advantage of separate systems would be the increased CPU and bandwidth available. As long as you are using a fast enough processor and memory, you should be fine. A normal 32 bit/33 Mhz PCI bus peaks at about 600 Mbits/sec. Double that for 64 bit and double again for 66 Mhz (PCI-X). PCI-express, not sure yet.
