RE: Well Known Multicast Addresses

Oops! excuse me (I need some rest):

I meant the address pair 224.0.1.39 and 224.0.1.40

Check here for the list of well-know MCAST addresses

http://www.iana.org/assignments/multicast-addresses/

The pair 224.0.0.39 and 224.0.0.40 are within the range of link-local
addresses reserved for Zero Configuration Networking.

Do you really mean them?

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.

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
