"Any fear" is subjective. It is completely possible that a node might start to send an SSM stream to that particular multicast address. > o Multicast source side > 1.

Why cannot the source check from LLMNR whether such a session, or such an address under that session does not already exist? (This is why I was stating that this kind of problems appear to be trivially solved as part of source discovery.) Apart from that.. Can you provide a bit of details what you're actually obtaining from LLMNR? Does the source register the address FF32:00ff:a12:34ff:fe56:7890::1 there, and just join to what you receive? If so, there is really no requirement for embedding EUI64 on the address, it's just something that's assumed to be reasonably unique. A constructive suggestion: reword this spec to use the upper bits of FF02::/16, even embedding the EUI64 if you wish, and publish it as an Informational RFC if you think an RFC is really needed. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
