Multicast & PIM Dense Mode

ITtech2010

Hi all,

I started working at a company as a Network Admin. It's a good job, a bit of a challenge and it's my first Networking job. My manager a Network Engineer wants me to learn Multicasting and PIM Dense Mode and IGMP Snooping. I've tried googling the information but it's just not clicking for me. Like I have the type of boss where if he asks me about say Multicast he doesn't just want "oh it's a series of msgs blah blah blah" But the whole IGMP process ect.....He doesn't have a lot of time to work on all multicast issues where there's a lot of gaps in the multicast feed. Does anyone have any sites that will bring the concept in my head?

I' want to make sure i understand it and I been slacking on my CCNP studies because I feel i need to learn my job first then prepare for CCNP but I need to learn HSRP, VRRP, Layer 3 switch. A whole lot and I want to learn as much as i can before he comes back from vacation on tuesday. Any help/sites that will break it down in simple terms i'd appreciate it a whole bunch.:)

i would say you have a lot of study to do.However, i would advise you to read IP multicasting.
Multicast Part 1 - Intro - YouTube . you can start from there and also spend time LABBING.
