OSPF Network Type Loopback

Hello All

 

Throughout my studies with OSPF, instructors have demonstrated the fact that this network type advertises routes as host routes, regardless of the mask configured.

 

My question is:

 

 

 

Why would you want to??

 

 

 

It is a loopback interface, after all and you are never going to have any more than one host on that network.

 

I cannot find any reason why you would need to advertise trhe full mask.

 

Unless I am missing something………..

 

 

I look forward to your responses.
