We have been provided with two options by our technology consultants to cater for Network Infrastructure in our new office building that spans across 20 floors with data center on 10th and IDFs on each floor.
*Attached Diagram Option I is using Cisco Cat 3750E at the access layer and Core and Distribution collapsed into a pair of 6509s.
* Option II is more high end with 4509s on the access layer and separated distribution and core layer (redundant).
But glaring in the diagram is the way two ASA 5540 are connected in failover mode. Seems like in both options I and II the consultants have multihomed it.
Is this possible? Is the representation right? I need to be sure of this point before I take this up for technical feasibility.
Also, any other concerns based on this diagrams that I should have..please advise!!
