1-5Field DescriptionDescription of route state:ActiveU An active unicast route, where “U” represents unicast.Blackhole A blackhole route is similar to a reject route, but no ICMPunreachable message is sent to the source.Delete A route is to be deleted.Gateway An indirect route.HiddenAn existing route that is temporarily unavailable for some reason (forexample, suppressed by a routing policy or down interface).However, deletion is not expected. It is therefore hidden so that itcan recover later.HolddownNumber of routes that are held down. Holddown is a routeadvertisement policy that some D-V based routing protocols (forexample, RIP) use to avoid the spread of wrong routes but speed upthe correct spread of ICMP unreachable messages. A certain routeis advertised at intervals, no matter whether the currently discoveredroute to the same destination changes. For details, refer to thespecific routing protocols.Int A route discovered by IGP.NoAdvise A routing protocol does not advertise any NoAdvise route whenadvertising routes in accordance with a routing policy.NotInstallA NotInstall route cannot be added to the core routing table, but maybe advertised. A route with the highest priority is generally selectedfrom the routing table, added to the core routing table, and thenadvertised.RejectThe routes marked with reject do not guide the router to forwardpackets as a normal route does. The router discards the packetsmatching reject routes and sends an ICMP unreachable message tothe source.Reject routes are usually used for network tests.RetainThe routes marked with retain will not be deleted when you deleteroutes in the core routing table. You can mark static routes withretain to make them stay in the core routing table.StaticThe routes marked with static will not be deleted from the routingtable after you perform a save operation and restart the router. Theroutes manually configured on a router are marked with static.StateUnicast A unicast route.Age Lifetime of a route in the routing table, in the format of HH:MM:SS.Cost Cost of a route.display ip routing-table ip-addressSyntaxdisplay ip routing-table ip-address [ mask | mask-length ] [ longer-match ] [ verbose ]ViewAny view
