Table 2 Command output

Field	Description
Destination	Destination address/mask length.
Protocol	Protocol that presents the route.
Process ID	Process ID.
Preference	Priority of the route.
Cost	Cost of the route.
IpPrecedence	IP precedence.
QosLcId	QoS-local ID.
NextHop	Address of the next hop on the route.
Interface	Output interface for packets to be forwarded along the route.
BkNextHop	Backup next hop.
BkInterface	Backup output interface.
RelyNextHop	Recursive next hop.
Neighbor	Neighboring address.
Tunnel ID	Tunnel ID.
Label	Label.
BKTunnel ID	Backup tunnel ID.
BKLabel	Backup label.
State	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. · Holddown—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 a Holddown route during a period regardless of whether a new route to the same destination is found. For detailed information, see corresponding routing protocols. · Int—The route was discovered by an Interior Gateway Protocol (IGP). · NoAdv—The route is not advertised when the router advertises routes based on policies. · NotInstall—In normal cases, among routes to a destination, the route with the highest priority is installed into the core routing table and advertised, while a NotInstall route 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 sources of the dropped packets. The Reject routes are usually used for network testing. · Static—A static route is not lost when you perform the save operation and 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.
Age	Time for which the route has been in the routing table, in the sequence of hour, minute, and second from left to right.
Tag	Route tag.

regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.

Description

Use display ip routing-table ip-address to display information about routes to a specified destination address.

Executing the command with different parameters yields different output:

· display ip routing-table ip-address

¡ The system ANDs the input destination IP address with the subnet mask in each route entry;

¡ The system ANDs the destination IP address in each route entry with its corresponding subnet mask;

¡ If the two operations yield the same result for an entry and this entry is active, it is displayed.

· display ip routing-table ip-address mask

¡ The system ANDs the input destination IP address with the input subnet mask;

¡ The system ANDs the destination IP address in each route entry with the input subnet mask;

¡ If the two operations yield the same result for an entry and the entry is active with a subnet mask less than or equal to the input subnet mask, the entry is displayed.

Only route entries that exactly match the input destination address and mask are displayed.

· display ip routing-table ip-address longer-match

¡ The system ANDs the input destination IP address with the subnet mask in each route entry;

¡ The system ANDs the destination IP address in each route entry with its corresponding subnet mask;

¡ If the two operations yield the same result for multiple entries that are active, the one with longest mask length is displayed.

· display ip routing-table ip-address mask longer-match

¡ The system ANDs the input destination IP address with the input subnet mask;

¡ The system ANDs the destination IP address in each route entry with the input subnet mask;

¡ If the two operations yield the same result for multiple entries with a mask less than or equal to the input subnet mask, the one that is active with longest mask length is displayed.

Use display ip routing-table ip-address1 { mask-length | mask } ip-address2 { mask-length | mask } to display route entries with destination addresses within a specified range.

Description

Use display ipv6 routing-table ipv6-address to display routing information about the specified destination IPv6 address.

Executing the command with different parameters yields different outputs:

· display ipv6 routing-table ipv6-address

¡ The system ANDs the input destination IPv6 address with the prefix length in each route entry;

¡ The system ANDs the destination IPv6 address in each route entry with the prefix length in each entry;

¡ If the two operations yield the same result for an entry and this entry is active, it is displayed.

· display ipv6 routing-table ipv6-address prefix-length

¡ The system ANDs the input destination IPv6 address with the input prefix length;

¡ The system ANDs the destination IPv6 address in each route entry with the input prefix length;

¡ If the two operations yield the same result for an entry and the entry is active with a prefix length less than or equal to the input prefix length, the entry is displayed.

Only route entries that exactly match the input destination address and prefix length are displayed.

· display ipv6 routing-table ipv6-address prefix-length longer-match

¡ The system ANDs the input destination IPv6 address with the input prefix length;

¡ The system ANDs the destination IPv6 address in each route entry with the input prefix length;

¡ If the two operations yield the same result for multiple entries with a prefix length less than or equal to the input prefix length, the one that is active with the longest prefix length is displayed.

Use display ipv6 routing-table ipv6-address1 ipv6-address2 to display routes whose destinations are in the specified IPv6 address range.
