Hello everyone! I have a WAN that comprises of 32 sites throughout the state of Nebraska. Each site has a 3725 series router.
I was at a conference and someone asked me if I made use of the loopback interface on my routers. I told him I didn't know much about this command on the router. I was then told that I should consider using the LoopBack Interface command on my routers. This person didn't really go into much detail for me after that.
Could someone provide me with some general information about this? Why would one use it? What's the benefit? Any general thoughts....
