NoAdv
NOADVISE route is not broadcast when each routing protocol is broadcast routes
according to Routing policy.
Int
The route is identified through IGP
Ext
The route is identified through EGP
Del Route
deleted
Active
Actually valid route
Retain
Usually, when a certain routing protocol is normally exiting, all the routes identified
by it will be deleted. However, those routes labeled with Retain will not be deleted.
Rej
These routes do not forward packets as normal routes do. Packets selecting routes
with the label of REJECT will be dropped, and such routes will send ICMP
unreachable message to the source of the packet. REJECT routes are usually
used for network tests or experiments.
Route state

Black
BLACKHOLE route is similar to REJECT route. The difference is that it does not
send the ICMP unreachable message to the source end of the packet.
Holddown
Holddown route means: a route broadcast policy adopted by some distance vector
routing protocols (like RIP) to avoid the broadcast of error routes and improve the
fast and accurate broadcast of the route unreachable message. Usually it
broadcasts a certain route regularly during an interval, no matter what change has
occurred to the route to the same destination currently retrieved. For detail, please
consul the routing protocols. The routing table statistics display the number of
routes held down currently.
Delete
Number of routes deleted.

Hidden
Some routes can not be used for a certain reason (like interface Down), but we do
not want them to be deleted. Therefore we hide them so that they can be
recovered. The routing table statistics display the number of currently hidden
routes.
