In reviewing the various docs on CCO it seems to alway show the 6120 FI dual homing to a pair of upstream core or aggragation switches. I;m trying to understand the advantages of dual homing vs just running strain port channels from Fabric A to its north bound switch and Fabric B to its northbound switch (assuming the northbound switches are not capable of VSS/VPC).
Refer to the Attached diagram if you would.
Option 1 is how I always see it in the CCO diagrams
If these links are not port-channels (just trunks) how does the FI decide which one to forward on for a given VNIC?
I guess the main question is which is the better design and why?
Hopefully my diagrams come out alright.....
