Re: [Mip6] On a network-mobility solution based on Mobile IPv6

[wenson <sunseawq at huawei.com>]

Since SEND only secure IP address of SEND Node and ND proxy should delegate any Node on the same local link to send packets with link local address of this Node as source IP address and ProxyNode'Mac address as source Mac Address.  
It seems ND proxy could not be used to in conjunction with SEND.

BTW, Does proxy ND have relay functionality,e.g.,ND relay?
If do, Is there any difference between them?
