Auto-RP and usage of "ip pim autorp listener"
After reading several forums with people arguing about what routers should be configured with the "ip pim autorp listener" command, I have decided to write this post explaining things in my own way (of course, with a lot of pictures, as usual).

Costi is a network and security engineer with over 10 years of experience in multi-vendor environments. He holds a CCIE Routing and Switching certification and is currently pursuing same expert-level certifications in other areas. He believes that the best way to learn and understand networking topics is to challenge yourself to fix different problems, production-wise or lab-type exams. He also enjoys teaching networking and security technologies, whevever there is an opportunity for it.
