Network requirements
As shown in Figure 31:
•
Switch A, Switch B, and Switch C that belong to the same AS and the same OSPF routing
domain are GR capable.
•
Switch A acts as the non-IETF GR restarter. Switch B and Switch C are the GR helpers, and
synchronize their LSDBs with Switch A through OOB communication of GR.
