They are used by Candidate RPs and Mapping agents when PIM-enabled
Cisco routers are running in sparse-dense mode
224.0.0.39 - AUTORPs communicate with MAs on this address
224.0.0.40 - Mapping agents tell PIM routers about the availability of RPs
Note that communication on these addresses is always dense-mode.

Subject: Well Known Multicast Addresses
Hi All,
I was making a quick list of well known multicast addresses and was confused
about these two, are 224.0.0.39 and 224.0.0.40 used for anything major ?
Thanks
Nick
