Configuring OSPFv3 GR
Network requirements
• As shown in Figure 100, Router A, Router B, and Router C that belong to the same AS and the same
OSPFv3 routing domain are GR capable.
• Router A acts as the GR restarter. Router B and Router C are the GR helpers, and synchronize their
LSDBs with Router A through out-of-band (OOB) communication of GR.
