Here you go. They will not be providing any routing or layer 3 service. I am just concerned about putting these 4 switches together in a 2 tier mlag. The 690 is 48 ports of 10gb and the x460 is 24 ports 1 gb ports. With the x690 having 200 gb between them and the x460 on 20gb there is a huge disparity between the separate isc bandwidth capabilities. If the pathing between the x690 would always take the 200gb link I would feel better about this setup.
My other design with eaps is similar below except the two isc and not tiered together. I have to use eaps to prevent the loops which adds complexity.
