After the restart, the GR Restarter will send an OSPF GR signal to its neighbors that will not reset their
adjacencies with it. In this way, the GR Restarter can restore the neighbor table upon receiving the
responses from neighbors.

After reestablishing neighbor relationships, the GR Restarter will synchronize the LSDB and exchange
routing information with all adjacent GR-capable neighbors. After that, the GR Restarter will update its
own routing table and forwarding table based on the new routing information and remove the stale
routes. In this way, the OSPF routing convergence is complete.
