I have a weird issue I cannot explain. I only picked it up because I was experimenting with queues to see if I could improve performance.
I have my bacbone vlan 172.17.0.0/24. This has all my servers backup etc. Backbone Router 172.17.0.1. I then have three segments. I have a router at each segment providing various vlans. There is not nat on these 3 routers.
segment 1 172.17.0.2
segment 2 172.17.0.3
segment 3 172.17.0.4
Lets say I am sitting behind router for segment 1 accessing a backup server on the backbone. If i download or upload a file to this server the traffic passes through the backbone router instead of being switched through the switch. If I connect directly to the backbone vlan switches my traffic does not pass through the backbone router.
Why is the traffic not switched directly instead of passing through backbone router when behind one of the segment routers.
