Attached is our existing network consisting of 5500. The plan is to replace them with 4506 chassis.
Referring to the diagram
Block 2 switch is acting as the VTP server and is connected to the edge routers
All other 5500's trunk to the Block 2 switch and hence VLANs are spread across
SVIs are created at each 5500 and are not centrally created on the block 2 switch
To connect at IP layer, all the RSM switches run EIGRP to learn the subnets
VLANs need to be spread across all the blocks even after this migration as there is dependency.
Should i be creating SVI's at each switch and then EIGRP again to connect them at Layer 3 or i would be better of creating all the SVI's in the block 2 switch and just have layer 2 trunks from other 4506?
What are the Pro's and Cons of both the approach?
