[support] can NEPL/UMIP support the VMN?

[Junkang Ma]

Dear Romain,

My test is to put the VMN in the NEMO moving network, and the VMN  
always connects to the MR. The HA or the CN outside the moving network  
pings to the Home Address of VMN. Then, I change the network interface  
of the MR to initiate the handover of the MR. After the handover, the  
ongoing ping communication (which is still pinging to the Home Address  
of VMN) can not reach the VMN.

However, I find that if the HA or the CN outside the moving network  
pings to the Car-of-address of VMN, which is the address that the VMN  
obtains from the MNP in the NEMO moving network, the ongoing ping  
communication can be kept continuous after the handover of the MR.

I will go to repeat the test, and send you the test log file in the  
future email.

Thank you very much,

Junkang
