Field Description
Holddown
Number of currently hold down routes –
Holddown refers to a route advertising
policy used by some distance vector
(D-V) routing protocols (such as RIP) in
order to avoid expansion of error routes
and improve fast and correct
transmission of unreachable routing
information. It usually advertises a route
fixedly at an interval no matter what
changes have happened to the routes to
the same destination, which have been
learned actually. For details, refer to the
specific routing protocol.
Delete
Number of routes that have been
deleted currently.
Hidden
Number of currently hidden routes --
Some routes are not available at present
for some reason (e.g., the interface is
Down) but are not expected to be
deleted. They can be hidden for future
restoration.
