Field Description
Descriptions on the route state are as follows:
ActiveU Valid unicast route. “U” stands for unicast.
Blackhole
Blackhole route is the same as reject route except that a
router drops a packet traveling along a blackhole route
without sending ICMP unreachable messages to the
source of the packets.
Delete The route is deleted.
Gateway The route is not a direct route.
Hidden
The route is a hidden route. For routes that are
temporarily unavailable for some reasons (such as the
policy configured or the interface is down), you can hide
them for later use.
Holddown
The route is held down. Holddown is a kind of route
advertisement policy used in some D-V (distance vector)
routing protocols (such as RIP) to avoid the propagation
of some incorrect routes and improve the transmission
speed of route-unreachable information. For details,
refer to corresponding routing protocols.
Int
The route is discovered by the internal gateway protocol
(IGP).
NoAdvise
The route is not advertised when the router advertises
routes based on policies
NotInstall
The route are not loaded to the core routing table but can
be advertised. Normally, the routes with the highest
preference in the routing table are loaded to the core
routing table and are advertised.
Reject
The packets travel along the 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 route is not deleted when the routes read from the
core routing table are deleted. You can enable static
routes to remain in the core routing table by configure
them to be in retain state.
Static
The route is not lost when you perform the save
operation and then restart the router. Routes marked as
Static are configured manually.
State
Unicast The route is an unicast route.
Age
Time period during which the route is allowed in the routing table, in
the form of hh:mm:ss.
