Configuring OSPFv3 GR
Network requirements
As shown in
•
OSPFv3 routing domain are GR capable.
Router B and Router C are MSR routers, and Router A is of another router model that supports GR
•
restarter function and active/standby switchover.
Router A acts as the GR restarter. Router B and Router C are the GR helpers, and synchronize their
•
