· 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 with a subnet mask not greater than 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 the following way:

- If the entered IP address belongs to class A, B, or C, the system ANDs it with the default subnet mask of the corresponding class.

- If the entered IP address is 0.0.0.0, the system ANDs it with the subnet mask 0.0.0.0.

- Except the previous cases, for example, if the entered IP address is a multicast address or loopback address, the system ANDs it with the subnet mask 255.255.255.255.

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

If the two operations yield the same result for multiple entries, all the entries are 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, all the entries are displayed.

· display ip routing-table ip-address1 to ip-address2

The system displays active route entries with destinations in the range of ip-address1/32 to ip-address2/32.

Table 5 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 of active routes alert	Alarm threshold of active routes specified by using the routing-table limit command in a VPN instance: · Threshold value of active routes alert—This field is displayed when the alarm threshold is specified by using the routing-table limit number simply-alert command. When the number of active routes exceeds the alarm threshold, the system logs the event and sends traps but still accepts active routes. · Threshold value percentage of max active routes—This field is displayed when the alarm threshold is specified by using the routing-table limit number warn-threshold command, 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 but still accepts active routes. 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, and multiplied by 100.

Parameters

ipv6-address: Specifies a destination IPv6 address.

prefix-length: Specifies the prefix length in the range of 0 to 128.

longer-match: Displays the route entries that meet the matching rules as described in the usage guidelines.

ipv6-address1 to ipv6-address2: Specifies a destination IPv6 address range.

Usage guidelines

Executing the command with different parameters yields different output.

· display ipv6 routing-table ipv6-address

¡ The system ANDs the entered destination IPv6 address with the prefix length in each active route entry.

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

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

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

¡ The system ANDs the entered destination IPv6 address with the entered prefix length.

¡ The system ANDs the destination IPv6 address in each active route entry with the entered prefix length.

If the two operations yield the same result for an entry with a prefix length not greater than the entered prefix length, the entry is displayed.

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

If you do not specify the prefix-length argument, the command yields the same result as the display ipv6 routing-table command.

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

¡ The system ANDs the entered destination IPv6 address with the entered prefix length.

¡ The system ANDs the destination IPv6 address in each active route entry with the entered prefix length.

If the two operations yield the same result for multiple entries, all the entries are displayed.

· display ipv6 routing-table ipv6-address1 to ipv6-address2

The system displays route entries with destinations in the range of ipv6-address1/128 to ipv6-address2/128.

ecmp mode

Use ecmp mode to configure the ECMP mode.

Use undo ecmp mode to restore the default.

Syntax

ecmp mode enhanced

undo ecmp mode

Default

The normal ECMP mode is used.

Views

System view

Predefined user roles

network-admin

Parameters

enhanced: Specifies the enhanced ECMP mode.

Usage guidelines

An ECMP route group contains ECMP routes to the same destination. The following ECMP modes are supported:

· Normal mode—When one or multiple ECMP routes in an ECMP group fail, this mode enables the device to reallocate all traffic to the remaining routes in the ECMP group.

· Enhanced mode—When one or multiple ECMP routes in an ECMP group fail, this mode enables the device to reallocate only the traffic of the failed routes to the remaining routes.

An ECMP route group contains ECMP routes to the same destination. Changing the ECMP mode also changes the number of supported ECMP groups. Make sure you understand the potential impact on the network before executing the command.

· In normal ECMP mode, the number of supported ECMP groups varies by the number of ECMP routes. The more ECMP routes, the less ECMP groups supported by the device (the minimum number of ECMP groups is 128).

· In enhanced ECMP mode, the device supports a fixed number of 128 ECMP groups.

This command takes effect after a device reboot. Before you reboot the device, make sure you understand the potential impact on the network.

If you execute the command multiple times, the most recent configuration takes effect.

This command applies to both IPv4 and IPv6 ECMP routes.

Examples

# Enable the enhanced ECMP mode.

<Sysname> system-view

[Sysname] ecmp mode enhanced

The configuration will take effect at the next reboot. Continue? [Y/N]:y

Reboot device to make the configuration take effect.

inter-protocol fast-reroute

Use inter-protocol fast-reroute to enable IPv4 or IPv6 RIB inter-protocol FRR.

Use undo inter-protocol fast-reroute to disable IPv4 or IPv6 RIB inter-protocol FRR.

Syntax

inter-protocol fast-reroute [ vpn-instance vpn-instance-name ]

undo inter-protocol fast-reroute [ vpn-instance vpn-instance-name ]

Default

Inter-protocol FRR is disabled.

Views

RIB IPv4 address family view

RIB IPv6 address family view

Predefined user roles

network-admin

Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, the command enables IPv4 or IPv6 RIB inter-protocol FRR for the public network.

Usage guidelines

This command allows a device to perform fast rerouting between routes of different protocols. A backup next hop is automatically selected to reduce the service interruption time caused by unreachable next hops. When the next hop of the primary link fails, the traffic is redirected to the backup next hop.

This command uses the next hop of a route from a different protocol as the backup next hop for the faulty route, which might cause loops.

Inter-protocol FRR cannot select a backup next hop from routes in the RIB that have the same next hop, output interface, and destination as those of the faulty route.

Examples

# Enable IPv4 RIB inter-protocol FRR for the public network.

<Sysname> system-view

[Sysname] rib

ip route fast-switchover enable

Use ip route fast-switchover enable to enable IPv4 route fast switchover.

Use undo ip route fast-switchover enable to disable IPv4 route fast switchover.

Syntax

ip route fast-switchover enable

undo ip route fast-switchover enable

Default

IPv4 route fast switchover is disabled.

Views

System view

Predefined user roles

network-admin

Usage guidelines

Use this command if a physical interface is the output interface for a large number of routes, including ECMP routes and primary/secondary routes. When a link failure occurs on an interface, the device typically performs the following operations before switching the traffic to a valid route:

1. Deletes all ARP entries for the link.

2. Instructs the FIB to delete the associated FIB entries.

This process is time-consuming and interruptive if a large number of routes traverse the interface. Route fast switchover minimizes traffic interruption by instructing the FIB to delete the affected FIB entries immediately without having to wait for the ARP entries to be deleted.

Examples

# Enable IPv4 route fast switchover.

<Sysname> system-view

[Sysname] ip route fast-switchover enable

ipv6 route fast-switchover enable

Use ipv6 route fast-switchover enable to enable IPv6 route fast switchover.

Use undo ipv6 route fast-switchover enable to disable IPv6 route fast switchover.

Parameters

protocol: Specifies a routing protocol, which can be bgp or static in RIB IPv4 address family view or bgp4+ or static in RIB IPv6 address family view.

route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters.

Usage guidelines

Configure routing policy-based recursive lookup to control route recursion results. For example, when a route changes, the routing protocol has to perform a route recursion if the next hop is indirectly connected. The routing protocol might select an incorrect path, which can cause traffic loss. To prevent this problem, you can use a routing policy to filter out incorrect routes. The routes that pass the filtering of the routing policy will be used for route recursion.

The apply clauses in the specified routing policy cannot take effect.

Make sure a minimum of one related route can match the routing policy for correct traffic forwarding.

Examples

# Configure recursive lookup based on routing policy policy1 for static routes.
