Table 204 Description on the fields of the display ip routing-table command
Field	Description
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.
Cost	Route cost
