When LMA (acting as DHCP Requesting Router) receives PBU, it will send DHCP Solicit Message to DHCP Delegation Router. DHCP Delegation Router in turn sends the Prefixe(s) to the Requesting Router through DHCP Reply Message. LMA will build PBA message with the received prefixe(s) and send it back to MAG. When there are multiple MN(s) connected to the MAG and MAG requests LMA for prefix assignment, how will the DHCP Delegation Router will allocate unique prefixes to each MN, since RFC5213 supports only per-MN-prefix model? [behcet] For each MN, LMA sets a different IA_ID in the Solicit message as explained in draft-sarikaya-netlmm-prefix-delegation. DR assigns unique prefixes. IA_ID is a 4-octet field, we suggested extending it to 8-octets but DHC WG did not favor it. Such a change would have made it easy to associate IA_ID s with the link layer IDs. Regards, Behcet Thanks S Magesh
