I have two designs for the call center in China. The option A is prefer. The option B is suggested by someone.
Which one is better and why?
For the option B, I need to connect two uplink cables to core switch. if "swicth A" is down, the uplink between "switch A" to another floors are down. That's why I need to connect second uplink to "switch B".
However, I do not know the option B to be the "normal design" or not.
Option A provides 2 independent switches with inter-switch speed links of 3Gbps (etherchanneled) while Option B provides one logical switch with backplane speed of 32Gbps (stacked).
As for dual uplink, with option B - I suggest doing the same, however one port will be blocking (same happens with Option A) while the other port will be forwarding from the leaf switches toward the stacked switch STP root.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
