Let me summarize the above.
1. In principle, a prefix is assigned to only one link, whether L=0 or not.
2. For multi-link subnet (the use of the same subnet prefix on multiple link),
special care is needed, for example ND proxying.
Right?
Thanks for enlightening comments. :-) I have clearer vision now.
