Re: [16NG] Fw: I-DACTION:draft-madanapalli-16ng-ipv4-over-802-dot-16-ipcs-00.txt

Hi Syam,
  You mentioned P2P link here in this message but I could not see any text on this in the draft. Maybe a section should be added on the address and subnet mask assignment given the P2P nature of the link and the fact that such assignments are not commonly used.
  You recommended AR to ignore ARP Requests from MS, I am not sure if this is OK or a Reply would be needed according to ARP?

Regards,

Behcet

As mentioned the draft, ARP is not required for 802.16 because of the fact
that the MAC address is not required for identifying the destination.
There was a concern that an unmodified host may send ARP without knowing
that the underlying interface is 802.16, because of this I added the
above statement.

If we think there is no such possibility, then I will remove this text.

The draft assumes the p2p link, so no two MSs can be on the same subnet.
