What is VLAN Load Balancing?

In layer 2 switching, the Ethernet frames should be received from the same port where it was sent, otherwise layer 2 switching or switching loop occurs.

Let me explain this concept with the topology depicted below (Figure -1).

In the above figure, either Port 1 or Port2 is used to send the traffic, and the same port should be used to receive the traffic. The switches use MAC addresses to process the Ethernet frames. Read more

What is a Micro Loop in Routing?

Micro loop can be found in fast-rerouted networks. Fast reroute, as a proactive convergence mechanism, provides sub-second data plane convergence.

If any link fails, upstream node sends the traffic through the repaired path to the downstream device. For the downstream node to be used as a backup/repair node, it should be loop-free.

What do all these mean? The picture below provides further explanations.
