interfaces, as governed by LSA’s flooding scope (see Section 13 of the RFC). When
multiple direct links connect two routers, the RFC-2328 flooding algorithm generates
significant redundant information across all links.
By default, Dell Networking OS implements an enhanced flooding procedure that
dynamically and intelligently determines when to optimize flooding. Whenever
possible, the OSPF task attempts to reduce flooding overhead by selectively flooding
on a subset of the interfaces between two routers.
When you enable flood-2328, this command configures Dell Networking OS to flood
LSAs on all interfaces.
graceful-restart grace-period
Specifies the time duration, in seconds, that the router’s neighbors continue to advertise the router as fully
adjacent regardless of the synchronization state during a graceful restart.
NOTE
: This command enables OSPFv2 graceful restart globally by setting the grace period (in seconds)
that an OSPFv2 router’s neighbors continues to advertise the router as adjacent during a graceful restart.
S6000–ON
Syntax
graceful-restart grace-period seconds
To disable the grace period, use the no graceful-restart grace-period
command.
Parameters
seconds Time duration, in seconds, that specifies the duration of the
restart process before OSPF terminates the process. The range is
from 40 to 1800 seconds.
Defaults Not Configured
