Lookback Interfaces In Cisco Are SUPER EASY!!!

[@ambster1]

Thank you for this, I finally understood that Loopbacks Interfaces are not physical but logical, I kept asking my Lecturer about these loopbacks but did not explained it well.

neat explanation - thank u very much!👍

This lookback example was quite easy and you did a great job. Can you produce more loopback videos with 3 routers, more ip address and each router pinging one another... You made it look so easy and my instructor makes it so complicated... Thanks

Why would you assign a /24 mask instead of a /32? Is there an advantage to doing it this way?

[@gerardodh1951]

it will be interesting in knowing how and where to use it. Configuring it is pretty easy for people

[@somethingidk8875]

you utilize them for traffic that's directed at the device itself, but you don't necessarily want the traffic to be limited via one singular interface. for example, management traffic or for routing protocols. you can have OSPF routes advertised to loopback interface IP addresses rather than a single interface's IP address.

Why i need to create this kind of interface? I dont know why because the configuration must be setted by console or other software máster to control the devices, if i dont need to access and managed it in remote ¿what is the function of this interface? Thank you

FYI: Before you explain how to config a loopback address, you might want to explain why we have the silly thing in the first place. Otherwise the whole process seems ridiculous.
