Hi,

I have a private = network which=20 is connected to 3 diffrent ISPs. I also have a linux box acting as a = gateway and=20 internet firewall for the internal network. The network is as shown=20 below

Linux=20 Gateway/Firewall

&nbs= p; |&nbs= p; =20

&nbs= p; |

&nbs= p; |

&nbs= p; =20 Ethernet Hub=20 ----------------------------------------------------------------------Eth= ernet=20 Hub--------|--

&nbs= p; =20 / | =20 =20 \ = &= nbsp; &n= bsp; &nb= sp; &nbs= p; = ; = |--&nbs= p; =20 Local Network

=20 / | = ; =20 =20 \ = &= nbsp; &n= bsp; &nb= sp; &nbs= p; = ; = |--

/ &nb= sp; | &nb= sp; =20 = \

ISP-I = =20 ISP-II =20 ISP-III

My problem is i have a couple of = sites which=20 are to be divided into 3 groups and each to be routed through a = particular isp (=20 this is generally choosen by the requirements of the site. Some of the = sites=20 need very fast

response time, some need large volumes = of data to=20 be transfered, and some need a very stable connection ).

Appart from these few sites the rest of = the traffic=20 is routed through one of the isp ( the one with the highest bandwidth )=20

And when a particular ISP fails the = routes=20 currently being used by this ISP is to be shifted to the other 2=20 ISPs.

I also require the routes to be restord = back to as=20 decided earlier once the isp which was down comes back

Is there any means to automise the whole process. The effective aim = is to=20 utilize the most of all the isps that are available at a moment of = time.

( At the moment we attain this via = static routing=20 and we have one personal monitoring this round the clock, in case a = rerouting is=20 necessary )

with regards,
Sushil=20 Suresh
