Valid unicast route. U stands for

unicast.
Blackhole
Blackhole route is similar to Reject
route, but it will not send the ICMP
unreachable message to the source end

Delete
The route is deleted
Gateway
Indicates that the route is not directly
reachable
reachable
Hidden
The route exists, but it is unavailable
temporarily for some reasons (e.g.,
configured policy or interface is Down).
Moreover, you do not wish to delete it.
Therefore, you need to hide it, so as to
restore it again later

Holddown
Holddown is one kind of route
redistribution policy adopted by some
distance-vector (D-V) routing protocols
(e.g., RIP), through which these routing
protocols can avoid the flooding of
error routes and deliver the routing
unreachable message accurately. For
example, the RIP imports a certain
route every a period of time regardless
of whether the actually found routes
destined for the same destination
change. For more details, refer to the
specific routing protocols.

NotInstall
The routing protocol generally selects
the route with the highest precedence
from its routing table, then places it in
its core routing table and imports it.
Although the NotInstall route cannot
be placed in the core routing table, it is
possibly that it is selected and
imported.

Reject
Unlike the normal routes, the Reject
route will discard the packets that
select it as their route, and the router
will send ICMP unreachable message to
the source end. Reject route is usually
used for the network test
