We are working on a project to an existing Legacy-Enterasys customer, to fight Aruba's approach on a customer using 2 X690 as Cores, and thinking about V400 Bridge Port Extenders for access (using 1G uplinks due to customer needs and infrastructure constrictions)...
The problem is the customer's "rings"... They are mandatory to the customer, because they want redundancy to the access. Do you think any of the following designs could work???
