Usage
In OSPF, flooding is the most resource-consuming task. The flooding algorithm,
Information
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, the system 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 the system to flood LSAs
on all interfaces.
