· display ip routing-table ip-address

¡ The system ANDs the entered destination IP address with the subnet mask in each active route entry.

¡ The system ANDs the destination IP address in each active route entry with its own subnet mask.

If the two operations yield the same result for an entry, the entry is displayed.

· display ip routing-table ip-address mask

¡ The system ANDs the entered destination IP address with the entered subnet mask.

¡ The system ANDs the destination IP address in each active route entry with the entered subnet mask.

If the two operations yield the same result for an entry and the entry has a subnet mask less than or equal to the entered subnet mask, the entry is displayed.

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

¡ The system ANDs the entered destination IP address with the subnet mask in each active route entry.

¡ The system ANDs the destination IP address in each active route entry with its own subnet mask.

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

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

¡ The system ANDs the entered destination IP address with the entered subnet mask.

¡ The system ANDs the destination IP address in each active route entry with the entered subnet mask.

If the two operations yield the same result for multiple entries and the entries have a mask less than or equal to the entered subnet mask, the one with the longest mask length is displayed.

Table 10 Command output

Field	Description
Max ECMP	Maximum number of ECMP routes supported by the system.
Max Active Route	Maximum number of supported routes.
Remain Active Route	Number of the remaining inactive routes.
Threshold value percentage of max active routes	Alarm threshold specified by using the routing-table limit number warn-threshold command in a VPN instance, in the range of 1 to 100 in percentage. When the percentage of active routes exceeds the alarm threshold, the system logs the event and sends traps. If the number of active routes reaches the maximum number, no more routes can be added. The percentage of active routes equals the number of active routes divided by the maximum number of active routes supported in a VPN instance. If the routing-table limit command is not configured for the VPN instance, this field displays the maximum number of active routes supported by the device.
Threshold value of active routes alert	Alarm threshold specified by using the routing-table limit number simply-alert command in a VPN instance. When the number of active routes exceeds the alarm threshold, the system logs the event and sends traps but still accepts active routes.

fib lifetime

Use fib lifetime to set the maximum lifetime for IPv4 or IPv6 routes in the FIB.

Use undo fib lifetime to restore the default.

Syntax

fib lifetime seconds

undo fib lifetime

Default

The maximum lifetime for IPv4 or IPv6 routes in the FIB is 600 seconds.

Views

RIB IPv4 address family view, RIB IPv6 address family view

Predefined user roles

network-admin

Parameters

seconds: Sets the maximum lifetime for routes in the FIB, in the range of 0 to 900 seconds. When this argument is set to 0, FIB entries immediately age out after a protocol or RIB process switchover.

Usage guidelines

When a protocol or RIB process switchover occurs and GR or NSR is not configured, FIB entries age out after the time specified in this command.

Examples

# Set the maximum lifetime for IPv4 routes in the FIB to 60 seconds.

<Sysname> system-view

[Sysname] rib

[Sysname-rib] address-family ipv4

[Sysname-rib-ipv4] fib lifetime 60

flush route-attribute

Use flush route-attribute to configure the RIB to flush route attribute information to the FIB.

Use undo flush route-attribute to remove the configuration.

Syntax

flush route-attribute protocol

undo flush route-attribute protocol

Default

The RIB does not flush route attribute information to the FIB.

Views

RIB IPv4 address family view

Predefined user roles

network-admin

Parameters

protocol: Specifies a protocol. Only BGP is supported.

Examples

# Configure the RIB to flush BGP route attribute information to FIB.

<Sysname> system-view

[Sysname] rib

[Sysname-rib] address-family ipv4

[Sysname-rib-ipv4] flush route-attribute bgp

protocol lifetime

Use protocol lifetime to set the maximum lifetime for IPv4 or IPv6 routes and labels in the RIB.

Use undo protocol lifetime to restore the default.

Syntax

protocol protocol lifetime seconds

undo protocol protocol lifetime

Default

The maximum lifetime for IPv4 or IPv6 routes and labels in the RIB is 480 seconds.

Views

RIB IPv4 address family view, RIB IPv6 address family view

Predefined user roles

network-admin

Parameters

seconds: Sets the maximum lifetime for routes and labels in the RIB, in the range of 0 to 900 seconds. When this argument is set to 0, RIB entries immediately age out when a protocol switchover occurs.

Usage guidelines

When GR is enabled, make sure the protocol can complete GR and install all route entries to the RIB within the lifetime configured in this command.

Examples

# Set the maximum lifetime for OSPF routes and labels in the RIB to 60 seconds.

<Sysname> system-view

[Sysname] rib

[Sysname-rib] address-family ipv4

[Sysname-rib-ipv4] protocol ospf lifetime 60

reset ip routing-table statistics protocol

Views

User view

Predefined user roles

network-admin

Parameters

vpn-instance vpn-instance-name: Clears the IPv4 route statistics for a VPN instance specified by its name, a case-sensitive string of 1 to 31 characters. If you do not specify this option, the command clears IPv4 route statistics for the public network.

protocol: Clears route statistics for a routing protocol. It can be bgp, direct, isis, ospf, rip, or static.

all: Clears route statistics for all IPv4 routing protocols.

standby slot slot-number: Clears backup IPv4 route statistics on the specified device. The slot-number argument specifies the IRF member device by its member ID. If you do not specify this option, the command clears IPv4 route statistics.

Examples

# Clear all IPv4 route statistics for the public network.

<Sysname> reset ip routing-table statistics protocol all

reset ipv6 routing-table statistics protocol

Use reset ipv6 routing-table statistics protocol to clear IPv6 route statistics.

Syntax

reset ipv6 routing-table statistics protocol [ vpn-instance vpn-instance-name ] { protocol | all } [ standby slot slot-number ]

Views

User view

Predefined user roles

network-admin

Parameters

vpn-instance vpn-instance-name: Clears route statistics for a VPN instance specified by its name, a case-sensitive string of 1 to 31 characters. If you do not specify this option, the command clears the IPv6 route statistics for the public network.

protocol: Clears route statistics for an IPv6 routing protocol. It can be bgp4+, direct, isisv6, ospfv3, ripng, or static.

all: Clears route statistics for all IPv6 routing protocols.

standby slot slot-number: Clears backup IPv6 route statistics on the specified device. The slot-number argument specifies the IRF member device by its member ID. If you do not specify this option, the command clears IPv6 route statistics.

Examples
