Chris,
Take a look at Cisco OER
http://www.cisco.com/en/US/netsol/ns471/
networking_solutions_package.html or Route Science
http://www.routescience.com/technology/index.html. You could also
continue doing what you are doing, The 12k supports BGP, Netflow, SNMP
and some custom scripts

I am hoping to learn from the great pool of experience on this list.
We currently have 2 OC3 connections going to 2 seperate providers. We
are using netflow statistics to balance our traffic flows (which
outgoing is our major concern). Flow tools, snmp output, some custom
scripts, and some bgp weighting does the trick.
We are in the process of upgrading to Cisco 12012 GSRs, and adding
additional connectivity. We need to find something we can use to do
the same type of thing on the 12012 GSR. The custom scripts work
fine.. but it appears some line cards don't support netflow.
1) Is there an open source software that will assist us in load
sharing?
2) Are there specific cards we need for netflow on a 12000 series? Is
the difference based on Line Card Engine (0,1,2,3,etc)?
3) Is there an alternate way to control outgoing traffic flow to
multiple upstreams using bgp (besides splitting the address range up
and blindly pointing chunks to each provider)?
Thanks,
