Main 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.
