ABSTRACT:
A method and system for determining route redistribution are disclosed. The method generally comprises receiving an information packet from a neighbor source. The information packet identifies the source as a stub router and specifies route types that the source will advertise. Upon receiving notice of a failed link within the network, query packets are sent only to neighboring devices that have not been identified as stub routers to request route information.
