Routing Convergence

In this video, we will address routing convergence, also known as convergence routing. We know we have Layer 2 switches that create Ethernet. So all endpoints physically connect to a Layer 2 switch. And if you are on a single LAN with one large VLAN, you are ready with this setup as switches work out of the box, making decisions based on Layer 2 MAC addresses.

So these Layer 2 MAC addresses are already assigned to the NIC cards on your hosts, so you don't need to do anything.

You can configure the switches to say that this MAC address is available on this port and this MAC is available on this port.

Still, it's better for the switch to dynamically learn this when the two hosts connected to it start communicating and sending traffic. So if you want a switch to learn the MAC address, send a ping, and it will dynamically do all the MAC learning.
