I work for a school district with the following configuration:
Two remote sites connect to a main site via T-1s, then the main site has 3 T-1s which provide Internet access, advanced content filtering and hosts our CallManager.
We are adding bandwidth via cable modem to each site and keeping our T-1s in place, primarily for VoIP , but there are also some services (web, file shares, etc.) hosted at the main site.
How can I accomplish the following:
- allow certain subnets (for teachers, administrators, secretaries) at the remote sites to use the faster Internet connections
- the student and voip subnets at the remote sites should continue to use the T-1s
- if the cable connection goes down, the teacher/admin subnet should failover to the T-1s.
At first I was thinking I could use a static IP route with acls to deny the student subnet to use the cable connection, but I think that cause the student network to fail.
