IP Routing Basics Configuration Commands display ip routing-table
Syntax display ip routing-table [ verbose ] View Any view Default Level 1: Monitor level Parameters verbose: Displays detailed routing table information, including that for inactive routes. With this keyword absent, the command displays only summary information about active routes. Description Use the display ip routing-table command to display brief information about active routes in the routing table. This command displays brief information about a routing table, with a routing entry contained in one line. The information displayed includes destination IP address/mask length, protocol, preference, cost, next hop and outbound interface. This command only displays the routes currently in use, that is, the optimal routes.

Label Label
Route status:
Active This is an active unicast route.
Adv This route can be advertised.
Delete This route is deleted.
Gateway This is an indirect route.
Number of holddown routes. 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. It distributes Holddown a Holddown route during a period regardless of whether a new route to the same destination is found. For details, refer to corresponding routing protocols.
Int The route was discovered by an Interior Gateway Protocol (IGP).
The route is not advertised when the router advertises routes based NoAdv on policies.
Normally, among routes to a destination, the route with the highest State preference is installed into the core routing table and advertised, NotInstall while a NotInstall route cannot be installed into the core routing table but may be advertised.
The packets matching a Reject route will be dropped. Besides, the router sends ICMP unreachable messages to the sources of the Reject dropped packets. The Reject routes are usually used for network testing.
A static route is not lost when you perform the save operation and Static then restart the router. Routes configured manually are marked as static.
Unicast Unicast routes
Inactive Inactive routes
Invalid Invalid routes
WaitQ The route is the WaitQ during route recursion.
TunE Tunnel
GotQ The route is in the GotQ during route recursion.
Time for which the route has been in the routing table, in the sequence of hour, minute, Age and second from left to right.

5 IPv6 Static Routing Configuration Commands
z The term router in this document refers to both routers and APs configured with routing capabilities.
z Support for IPv6 static routing commands depends on the AP model.
IPv6 Static Routing Configuration Commands ipv6 route-static
Syntax For a broadcast interface (Ethernet interface, VLAN interface), or NBMA interface (X25 or frame relay interface): ipv6 route-static ipv6-address prefix-length nexthop-address [ preference preference-value ] undo ipv6 route-static ipv6-address prefix-length [ nexthop-address ] [ preference preference-value ] View System view Default Level 2: System level Parameters ipv6-address prefix-length: IPv6 address and prefix length. nexthop-address: Next hop IPv6 address. preference-value: Route preference value, in the range of 1 to 255. The default is 60. Description Use the ipv6 route-static command to configure an IPv6 static route.
5-1
Use the undo ipv6 route-static command to remove an IPv6 static route. An IPv6 static route that has the destination address configured as ::/0 (a prefix length of 0) is the default IPv6 route. If the destination address of an IPv6 packet does not match any entry in the routing table, this default route will be used to forward the packet. While configuring a static route, specify the next hop address as needed. If the output interface of the static route is a broadcast interface, such as an Ethernet interface or a VLAN interface, you must specify the next hop address. Related commands: display ipv6 routing-table (IP Routing Basics in the Layer 3 – IP Routing Command Reference). Examples # Configure a static IPv6 route, with the destination address being 1:1:2::/24 and next hop being 1:1:3::1.

6 Static Routing Configuration Commands
The term router in this document refers to both routers and APs configured with routing capabilities.
Static Routing Configuration Commands ip route-static
Syntax ip route-static dest-address { mask | mask-length } next-hop-address [ preference preference-value ] undo ip route-static dest-address { mask | mask-length } [ next-hop-address ] [ preference preference-value ] View System view Default Level 2: System level Parameters dest-address: Destination IP address of the static route, in dotted decimal notation. mask: Mast of the IP address, in dotted decimal notation. mask-length: Mask length, in the range 0 to 32. next-hop-address: IP address of the next hop, in dotted decimal notation. preference preference-value : Specifies the preference of the static route, which is in the range of 1 to 255 and defaults to 60.
6-1
Description Use the ip route-static command to configure a unicast static route. Use the undo ip route-static command to delete a unicast static route. When configuring a unicast static route, note that: 1) If the destination IP address and the mask are both 0.0.0.0, the configured route is a default route. If routing table searching fails, the router will use the default route for packet forwarding. 2) Different route management policies can be implemented for different route preference configurations. For example, specifying the same preference for different routes to the same destination address enables load sharing, while specifying different preferences for these routes enables route backup. 3) Do not specify the IP address of a local interface as the next hop address. Otherwise, the route configuration does not take effect. Related commands: display ip routing-table (IP Routing Basics in the Layer 3 – IP Routing Command Reference).
The static route does not take effect if you specify its next hop address first and then configure the address as the IP address of a local interface, such as a VLAN interface.
Examples # Configure a static route, whose destination address is 1.1.1.1/24, and next hop address is 2.2.2.2.
