Now studing for the BCMSN with the CiscoPress BCMSN Vol. 4 pg. 187 Figure8-2.
My question refers to a scenario where PC1 is connected to 2 switches for redundancy and forwarding a frame to the PC4 on the other side.
I understand the concept of a switching loop ...but this has me hung up.
It says "lets assume that both switches know the mac address both of the PCs in question. It then states that "both switches will receive the frame on their incoming ports". Then it will forward the frames on to PC4 and PC4 will receive both frames. It states "this is not ideal, but not disasterous either".
Question 1 : How/Where did the frame get duplicated? (the frame is received on both incoming switch interfaces)
Am I missing somthing here?
Any help is appreciated.
