I am trying to stand up a new stand alone network using three layer 3 3850's. The back side of these switches will have several layer two switches to provide access connectivity. I have created the vlans on the layer 3 switches and can communicate independently to the layer 2 switches that are directly connected to them, the problem is having the communication traverse the link between the two layer three devices. Attached is a rough layout with base configs. I am not able to get between the two "hub" layer 3 switches. What do I need to add in order to pass vlan traffic across?
what you are showing is a lan routed access design
Each access switch will have a routed port or svi of its designated vlan connected to the L3 switch running an igp such as ospf or a static route pointing towards it.
These subnets will be advertised in the igp (ospf) between the two L3 switches
So can you confirm this is what you have presently?
