Abstract A method to enhance a graceful restart process in an open shortest path first (OSPF) network is disclosed. The method is implemented on an OSPF enabled router that is adjacent to a plurality of neighboring OSPF enabled routers within a network, where the OSPF enabled router and the plurality of neighboring OSPF enabled routers are within one area of the network. In preparation of a database synchronization process during a graceful restart (GR) session, the OSPF enabled router selects a first neighboring OSPF enabled router from the plurality of neighboring OSPF enabled routers, initiates a first database synchronization with the first neighboring OSPF enabled router. Then the OSPF enabled router initiates 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.
