olsrd chooses one.
Basically it is irrelevant which of the several IP addresses (out of all
the locally configured ones - you might have mentioned more than one
physical interface in olsrd.conf) of a node is used as the "main
address" - it is just used as the "primary key" (in database speak) of
that node.
All other IP addresses (of the interfaces mentioned in olsrd.conf) are
also announced and usable, of course.
