This guide is platform-specic. For command information about other platforms, refer to the relevant Dell
Networking OS Command Line Reference Guide.
The following is a list of the Dell Networking OS version history for this command.
Version Description
9.1.(0.0) Introduced on the S4810 and Z9000.
8.4.2.2 Introduced on E-Series TeraScale.
8.3.19.0 Introduced on the S4820T.
Usage Information
By default, OSPFv3 graceful restart is disabled and functions only in a helper role to help restarting neighbor
routers in their graceful restarts when it receives a Grace LSA.
When congured in a helper-reject role, an OSPFv3 router ignores the Grace LSAs that it receives from a
restarting OSPFv3 neighbor.
The graceful-restart role command is not supported in OSPFv3. When you enable the helper-reject role on
an interface, you recongure an OSPFv3 router to function in a “restarting-only” role.
ipv6 ospf hello-interval
Specify the time interval between the hello packets sent on the interface.
Syntax
ipv6 ospf hello—interval seconds
To return to the default time interval, enter no ipv6 ospf hello—interval.
