Abstract
In general, the disclosure presents techniques for creating and maintaining routing information within a passive optical network. A PON interface receives a DHCP request to obtain a network address from a client represented by a node. The PON interface maps a particular interface module on which the client resides to unique client information, e.g., a media access control (MAC) address or other identifier, included in the DHCP request. The PON interface forwards the request to a DHCP server that returns a DHCP response indicating an administered IP address and lease time for the requesting client. Upon receipt of the DHCP response, the PON interface updates the mapping to create routing information for routing packets to the administered addresses. For example, PON interface may map the administered IP address to the particular interface module on which the client resides.
