I would like to make a design with 4 Nexus 5596UP. 2 of them equipped with Layer 3 Expansion Module so they can serve as core layer and the other 2 Nexus used as Layer 2 for aggregation server layer.
- The 2 Nexus in the core layer will run HSRP and will peer with ISP via BGP for Internet connection
- The 2 Nexus in the aggregation layer will be configured as layer 2 device and have FEX and switches connected to them
What I am ensure of is how the vpc and port-channel configuration should look like between the 4 nexus. What I was thinking is to run vpc between the 2 Nexus in the aggregation layer and between the 2 Nexus in the core layer. Than I was thinking of connecting each Nexus in the aggragtion layer to both Nexus in the core layer using port-channel and vice-versa.
I have made a drawing og the design I have described above:
Do you have any recommendations/comments or improments to this design?
