We are going to be replacing our mixed Dell and Cisco switching environment with an all Cisco solution as you can see in the attachment. We consolidated a great many of Dell and Cisco switches in our data center with the 4510R-E we recently purchased.
What we have now are two Dell switches with all access layer switches directly connected to both core switches via fiber. Using VRRP, one does all interVLAN routing using the directly connected VLANs. If one core dies, the other router takes over via VRRP.
We cannot do the Cisco routed layer 3 design so what I plan to do is pretty much the same thing but use HSRP for the redundancy component. I have two questions for our new design...
1) Is there any advantage or reason that we would want to implement a routing protocol into this network?
2) If we go the HSRP route, is there any reason that the two core switches should not be directly connected?
