I have a question regarding a simple Layer 2 setup. Current setup is ACCESS1 connects to CORE-1 and CORE-2. CORE-1 and CORE-2 both connect to an outbound GW/ROUTER. ACCESS1, CORE-1, and CORE-2 are all switches running a single VLAN.
My question is such: Being that CORE-1 and CORE-2 do not have any inter-switch links, there are no Spanning Tree Loops, so what happens b/c there are actually 2 uplinks. Are they both used and load balanced between or since the MAC address of the GW/ROUTER is learned out of a single uplink, the second would actually be in a "quasi-standby" state. Is this a way of "load balancing per destination IP address?"
I'm actually looking to migrate off this design, but want to understand what is actually going on right now.
