Sorry, I was too eager to respond. The assignees of the 32 bit ASN  
will have to ask for
space from IANA from the former "eGLOP" space, now the Extended AD-HOC  
space.

There will be no automatic pre-assignment of space,
see http://www.ietf.org/internet-drafts/draft-ietf-mboned-rfc3171bis-03.txt
for details.

This has not become an RFC yet, and if people have comments, we  
welcome them on the MBONED list.

Marshall

No, likely not.
