Field Description
Route state description:
ActiveU The route is selected and is optimum
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 Identifies that the route is not an interface route
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 redistributes 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.
Int
The route is discovered by interior gateway protocol
(IGP).
NoAdvise
The routing protocol does not redistribute NoAdvise
route when it redistributes routes based on the policy.
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 redistributes it.
Although the NotInstall route cannot be placed in the
core routing table, it is possibly that it is selected and
redistributed.
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
Retain
When the routes from the routing table are deleted, the
routes with Retain flag will not be deleted. Using this
function you can set Retain flag for some static routes,
so that they can exist in the core routing table.
Static
The route with Static flag will not be cleared from the
routing table after you save it and reboot the router.
Generally, the static route configured manually in the
router belongs to a Static route.
State
Unicast Unicast route
