We currently have the setup that is attached to this post. Currently due to certain bandwidth limits by our providers we are statically using routemaps routing traffic between the distribution and core routers to each provider for each of our network segments.
Now we want to change this and run a protocol between the core and distribution layer so all clients on the access layer will have the best path outwards to the internet.
Is it possible or even advisable to run BGP on the distribution layer as well so that it will know which core router A or B to send the traffic to? My thinking is that way it will have the same routing table as the core routers and be able to plot the best path.
Also can someone point me to ANY whitepapers/configuration guides, etc that can give me detailed commands/listing of how to implement a network design like this, core/distribution/access.
