1. A method, comprising:

  • discovering, at an aggregation network node, a plurality of network devices directly coupled to the aggregation network node, the plurality of network devices including a core network node and an access network node;

    sending, from the aggregation network node and to the core network node and the access network node, a plurality of portions of incomplete network topology information, each portion of incomplete network topology information from the plurality of portions of incomplete network topology information including a list of network devices directly coupled to the aggregation network node;

    receiving, at the aggregation network node, a first updated portion of incomplete network topology information from the core network node and a second updated portion of incomplete network topology information from the access network node, the first updated portion of incomplete network topology information being defined by the core network node based on (1) the plurality of portions of incomplete network topology information and (2) a network topology that was discovered by the core network node before the plurality of portions of incomplete network topology information was sent, the second updated portion of incomplete network topology information being defined by the access network node based on (1) the plurality of portions of incomplete network topology information and (2) a network topology that was discovered by the access network node before the plurality of portions of incomplete network topology was sent; and

    updating complete network topology information stored at the aggregation network node based on the first updated portion of incomplete network topology information and the second updated portion of incomplete network topology information.
