All things related to multicast

[Bill Nickless <>]

How about doing something like this for the multicast groups that IANA 
hasn't yet allocated, or are otherwise unusable for various reasons?

What I like about it is that it's automated, rather than depending on a 
human in the loop everywhere to watch for IANA announcements.

Having only spent about 20-30 seconds thinking about it, I'm not sure 
whether it's possible to configure popular routers to black-hole traffic 
destined for groups that are in a table populated by BGP.  Maybe an 
inspiration will strike later?

Yep, and the lesson is:  Lots of folks do a poor job of network
management.  :(

Keeping up with the bogons can be automated, see:
