Required
Not disabled by default
After an OSPF interface is set to silent, direct routes of the interface can still be advertised in
Intra-Area-Prefix-LSAs via other interfaces, but other OSPFv3 packets cannot be advertised. Therefore,
no neighboring relationship can be established on the interface. This feature can enhance the
adaptability of OSPFv3 networking.

Configuring OSPFv3 GR
You cannot configure OSPFv3 GR after configuring OSPFv3 virtual links, becase they are not
supported at the same time.
To prevent service interruption after a master/backup switchover, a GR Restarter running OSPFv3 must
complete the following tasks:
z
Keep the GR Restarter forwarding entries stable during reboot.
z
Establish all adjacencieis and obtain complete topology information after reboot.
After reboot, the GR Restarter sends a Grace-LSA to tell its neighbors that it performs a GR. Upon
receiving the Grace-LSA, the neighbors with the GR Helper capability enter the helper mode (and are
