Juniper QFX3000-G QFabric, Deployment Manual, Page: 431 / 652

NOTE:
Restart signaling-based helper mode is not supported for OSPFv3
configurations. To disable helper mode for OSPFv3 configurations, include
the
helper-disable statement at the [edit protocols ospfv3 graceful-restart]
hierarchy level.
TIP: You can also track graceful restart events with the
traceoptions
statement
at the
[edit protocols (ospf | ospf3)]
hierarchy level. For more information,
see “Tracking Graceful Restart Events” on page 405 .
NOTE: If you configure BFD and graceful restart for OSPF, graceful restart
might not work as expected.
Tracking Graceful Restart Events
To track the progress of a graceful restart event, you can configure graceful restart trace
options flags for IS-IS and OSPF/OSPFv3. To configure graceful restart trace options,
include the
graceful-restart
statement at the
[edit protocols protocol traceoptions flag]
hierarchy level:
[edit protocols]
isis {
traceoptions {
flag graceful-restart;
}
}
(ospf | ospf3) {
traceoptions {
flag graceful-restart;
}
}
