Layer 3 etherchannel

Layer 3 etherchannel

Layer 3 switches or multi-layer switch are devices that switch and route packets in the switch hardware itself
A layer 3 etherchannel is a connection make up of a logical grouping of ports into a virtual interface that is configurable as a routed interface.

We are going to use layer 3  mostly on core and distribution and distribution layer for routing purpose .

That group of ports are routing ports instead of switch ports .In the next graphic you will understand better the difference .

As we did before  in the previous exercise this is our  actual topology

We are going to provide some explanation of different commands  that we are going to use in switch A initially..So it will be better for you to understand

Configuration of Switch A

So we will apply all the previous information on  Switch A

Now let's work something similar in Switch C..Very similar  but in changes in the ip address

Let's apply these changes..

Now let's check with the command show ip int brief

We see here  the fa0/9 and fa0/10 , the port channel 10 we created is up and the loopback  is up as well

If you want extra confirmation of ospf relationship use the command show ospf neighbor and show ip route..
That's how we create an extra bandwidth on a routed link  using layer 3 etherchanel ..Meanwhile..this exercise is done..

If you understood the explanation and like it,..please share !
