Claim:
1. A method implemented on an Open Shortest Path First (OSPF) enabled router that is adjacent to a plurality of neighboring OSPF enabled routers within a network, wherein the OSPF enabled router and the plurality of neighboring OSPF enabled routers are within one area, wherein the OSPF enabled router and the plurality of neighboring OSPF enabled routers support an implementation of a graceful restart (GR) protocol, the method comprising: in preparation of a database synchronization process of the OSPF enabled router during a GR session, wherein the OSPF enabled router is a GR restarting router, selecting a first neighboring OSPF enabled router from the plurality of neighboring OSPF enabled routers, wherein the first neighboring OSPF enabled router is a single router selected from the plurality of neighboring OSPF enabled routers; initiating a first database synchronization with the first neighboring OSPF enabled router; and initiating a set of database synchronizations with remaining neighboring OSPF enabled routers only after the first database synchronization with the first neighboring OSPF enabled router completes, wherein each of the set of database synchronizations includes exchanging one or more database description packets.
