Usage
Information
In OSPF, flooding is the most resource-consuming task. The flooding algorithm, described in
RFC-2328, requires that OSPF flood LSAs (Link State Advertisements) on all 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, FTOS 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 FTOS to flood LSAs on all
interfaces.
graceful-restart grace-period
Specifies the time duration, in seconds, that the router’s neighbors will continue to advertise the router as fully adjacent
regardless of the synchronization state during a graceful restart.

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 40 to 1800
seconds.
Defaults
Not Configured
