Configuring OSPFv3 GR
Network requirements

As shown in
Figure 1-4
, Switch A, Switch B and Switch C that belong to the same AS and the same
OSPFv3 routing domain are GR capable.

Switch A acts as the GR Restarter. Switch B and Switch C are the GR Helpers and synchronize
their LSDBs with Switch A through out-of-band (OOB) communication of GR.
