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

ISP-I
ISP-II
ISP-III
My problem is i have a couple of sites which
are to be divided into 3 groups and each to be routed through a particular isp (
this is generally choosen by the requirements of the site. Some of the sites
need very fast
response time, some need large volumes of data to
be transfered, and some need a very stable connection ).
Appart from these few sites the rest of the traffic
is routed through one of the isp ( the one with the highest bandwidth )
And when a particular ISP fails the routes
currently being used by this ISP is to be shifted to the other 2
ISPs.
I also require the routes to be restord back to as
decided earlier once the isp which was down comes back
Is there any means to automise the whole process. The effective aim is to
utilize the most of all the isps that are available at a moment of time.
( At the moment we attain this via static routing
and we have one personal monitoring this round the clock, in case a rerouting is
necessary )
