When assigning administratively scoped multicast groups for SSM/Source Specific multicast usage, what is the appropriate range to use? I know 232.0.0.0/8 is a general SSM range, but is there a subsection that is best used for "administratively-scoped" or internal-use only addresses? In the ASM model, this was typically within different subsections of the 239/8 range. I can't seem to find this issue addressed in the appropriate RFCs for SSM.
Additionally, I know Cisco equipment permits the usage of SSM on non-standard multicast ranges. Are there any particular drawbacks or benefits to using SSM methodology on a 239/8 address instead of 232/8? However, I assume one drawback of me choosing to use a proper 232 SSM address is it becomes no longer possible to use ASM to the first router with SSM-mapping converting it to a SSM join. Is this true?
