[Qin]: It is  a interesting issue. What scenario do we need to think about?
Suppose the CN is a regular IPv6 node without PMIP protocol support,
It seems difficult to utitlize any PMIP6 protocol to estalish direct Path between the CN
and the MAG which the MN attaches to. Based on this, only one scenario occur to me is 
one mobile node and one regualr IPv6 node attahes to the same MAG. Is there any other scenario I miss?
if someone can do some clarification, it would be helpful.

[Qin];Thank you for your initiating this discussion, it is helpful for us to move the PMIPv6 local routing work forward .

I think it makes sense to send a
