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, 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.
