My College has two 10Mb connections to two ISPs.
The campus has 4 Class C networks from the one ISP.
202.128.71.x
202.128.72.x
202.128.73.x
202.128.79.x
The Router has the .1 on all 4 networks.
The second ISP connects to the same router, but links via the IP address
202.151.91.113.
The routing all goes the the router, and thru some systems, some IP
addresses go normal route, and others seem to be NATed thru the other
ISP.
I have no ideal on how they have it configure.
Now for what I have running. Had a squid server running on 202.128.73.28
that uses the Main ISP and that has worked fine. I then setup a second
Squid on 202.128.71.129 that is routed thru the other ISP. So, the computers
in my Classroom can use either of the two ISPs based on which squid server
they are set to us.
This works OK, and if one checks the load on the networks, one can use the
one least used.
Is there a way to set the squid servers so they can use both paths most
efficently.
Squid built with --enable-icmp and related pinger helper install will
test network load on all paths to destinations, selecting the fastest or
shortest link.
Building both Squid this way and not disabling netdb-exchange between
them makes them share their knowledge of the network topology and
destination speeds on a regular basis.
NP: Be prepared for some false security complaints from people who don't
understand what ICMP is designed for or how it works.
