State Route status:
ActiveU This is an active unicast route. U means unicast.
Blackhole A blackhole route is similar with a reject route except that a
router drops packets matching a blackhole route without
sending ICMP unreachable messages to the source of the
packets.
Delete This route is deleted.
Gateway This is an indirect route.
Hidden This route is hidden. For routes that are temporarily unusable for
some reasons (because of a policy configured or because the
interface is down), you can hide them for later use.
Holddown The route is suppressed. Holddown is a route advertisement
policy used in some distance vector (D-V) routing protocols, such
as RIP, to avoid the propagation of some incorrect routes and
improve the transmission speed of unreachable route
information. It distributes a certain route during a period
regardless of whether a new route to the same destination is
found. For details, refer to “IS-IS Configuration Commands” on
page 1037 and “Multicast Routing and Forwarding
Configuration Commands” on page 1327.
Int The route was discovered by an Internal Gateway Protocol (IGP).
NoAdvise The route is not advertised when the router advertises routes
based on policies.
NotInstall Normally, the routes with the highest preference in the routing
table are installed into the core routing table and are advertised,
while the NotInstall routes cannot be installed into the core
routing table but can be advertised.
Reject The packets matching a Reject route will be dropped. Besides,
the router sends ICMP unreachable messages to the source of
the dropped packets. The Reject routes are usually used for
network testing.
Retain The Retain routes are not deleted when the routes read from the
core routing table are deleted. You can keep static routes in the
core routing table by configuring them as Retain routes.
Static A Static route are not lost when you perform the save operation
and then restart the router. Routes configured manually are
marked as static.
Unicast Unicast routes
Age Age of the route in the routing table, in the form of hh:mm:ss.
