display ip routing-table ip-address

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

Use display ip routing-table ip-address1 to ip-address2 to display information about routes to a range of destination addresses.

Syntax

display ip routing-table [ vpn-instance vpn-instance-name ] ip-address [ mask-length | mask ] [ longer-match ] [ verbose ]

display ip routing-table [ vpn-instance vpn-instance-name ] ip-address1 to ip-address2 [ verbose ]

Views

Any view

Predefined user roles

network-admin

network-operator

Parameters

ip-address: Specifies a destination IP address in dotted decimal notation.

mask-length: Specifies the mask length, an integer in the range of 0 to 32.

mask: Specifies the IP address mask in dotted decimal notation.

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

ip-address1 to ip-address2: Specifies a destination IP address range.

verbose: Displays detailed routing table information, including information about both active and inactive routes. If you do not specify this keyword, the command displays brief information about active routes.

Usage guidelines

Executing the command with different parameters yields different outputs.

· 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.

Parameters

flush: Displays the records for the route entries issued by the RIB to the FIB.

notify: Displays the records for the route entries notified by the RIB to the routing protocol.

receive: Displays the records for the route entries received by the RIB from the routing protocol.

add: Displays the records for the added route entries.

delete: Displays the records for the deleted route entries.

update: Displays the records for the updated route entries. If you specify the flush or notify keyword, the system takes added route entries as updated route entries when displaying the associated records.

verbose: Displays detailed information about IPv4 route entry records. If you do not specify this keyword, the command displays only brief information about IPv4 route entry records.

Usage guidelines

If you do not specify the add, delete, or update keyword, the command displays records for the added, deleted, and updated route entries.

When the system enters the level-1 memory threshold alarm status, it stops recording new route entry information. When the system enters the level-3 memory threshold alarm status, it clears existing route entry records. When the system exits the level-1 memory threshold alarm status, it starts recording new route entry information again.

Table 13 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 xxx	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 routing-table limit number simply-alert command is not configured or when the alarm threshold is specified by using the routing-table limit number warn-threshold command. The value range for the alarm threshold is 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

flush: Displays the records for the next hops issued by the IPv6 RIB to the FIB.

receive: Displays the records for the next hops received by the IPv6 RIB from the routing protocol.

add: Displays the records for the added next hops.

delete: Displays the records for the deleted next hops.

update: Displays the records for the updated next hops. If you specify the flush keyword, the system takes added next hops as updated next hops when displaying the associated records.

verbose: Displays detailed information about next hop records. If you do not specify this keyword, the command displays only brief information about next hop records.

Usage guidelines

If you do not specify the add, delete, or update keyword, the command displays records for the added, deleted, and updated next hops.

When the system enters the level-1 memory threshold alarm status, it stops recording new next hop information. When the system enters the level-3 memory threshold alarm status, it clears existing next hop records. When the system exits the level-1 memory threshold alarm status, it starts recording new next hop information again.

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 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.

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.

Syntax

undo ipv6 route fast-switchover enable

Default

IPv6 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 ND 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 ND entries to be deleted.

Examples

# Enable IPv6 route fast switchover.

<Sysname> system-view

[Sysname] ipv6 route fast-switchover enable

Usage guidelines

A recursion loop occurs when a route recurses to a related route that recurses back to the route. It causes a route recursion failure and further lookup for a related route. If recursion loop persists, continuous route flapping will cause high system resource consumption and CPU utilization.

This command enables the system to use a counter to record the number of route recursion failures. When the counter reaches 20, the system suppresses route recursion for a specified period of time to save system resources on the device.

Parameters

ctrl: Specifies the BFD control packet mode.

echo: Specifies the BFD echo packet mode.

inter-protocol-frr: Enables primary route next hop detection for inter-protocol FRR.

protocol-ecmp protocol: Enables primary route next hop detection for ECMP routes of a routing protocol.

· In RIB IPv4 address family view, the value for the protocol argument can be bgp, isis, ospf, or static.

· In RIB IPv6 address family view, the value for the protocol argument depends on the BFD mode.

¡ In BFD control packet mode, the value can be bgp4+, isisv6, ospfv3, or static.

¡ In BFD echo packet mode, the value can be bgp4+ or static.

Usage guidelines

After you configure this command, device automatically creates an IP FRR BFD session to detect the next hop availability of the primary route. Upon primary route next hop failure, traffic can be immediately switched to the backup route next hop for fast convergence.

· For inter-protocol FRR, the primary route is the route with the highest preference among the routes to the same destination.

· For ECMP routes of a routing protocol, the primary route is each ECMP route. If you specify the ecmp-shared keyword when configuring FRR for a routing protocol, the device will use the LFA algorithm to calculate backup next hops for each ECMP route. The routes destined for the backup next hops are also added to the routing table as ECMP routes and the state of these routes is backup. BFD does not detect these backup ECMP routes.

This command takes effect and automatically creates a BFD session only when the primary route exists and a backup next hop is generated for it.

You can execute this command multiple times to change the BFD mode (echo packet mode or control packet mode).

If you do not specify the inter-protocol-frr or protocol-ecmp keyword, the command applies to both inter-protocol FRR and ECMP routes. The command without the inter-protocol-frr and protocol-ecmp keywords takes precedence over that with the inter-protocol-frr or protocol-ecmp keyword. For example, if you have used the primary-path-detect bfd ctrl command, you can use only the following commands to modify or cancel the command configuration:

· primary-path-detect bfd echo.

· undo primary-path-detect bfd.

A control-packet-mode BFD session can be successfully established through negotiation between the two ends. To use a control-packet-mode BFD session to detect the primary route next hop availability, you must create a static BFD session that meets the following requirements on the next hop device:

· Create a single-hop BFD session in control packet mode.

· The source IP address of the BFD session is the destination IP address of the BFD session automatically created by the local end.

· The destination IP address of the BFD session is the source IP address of the BFD session automatically created by the local end.

· The remote discriminator of the BFD session is the local discriminator of the BFD session automatically created by the local end.

The local device can use a control-packet-mode BFD session to detect the primary route next hop only after you create the static BFD session on the primary route next hop device. For more information about creating static BFD sessions, see BFD configuration in High Availability Configuration Guide.

When another protocol (for example, BGP, OSPF, and IS-IS) uses BFD to detect the primary route next hop, it also automatically create a BFD session. If the next hop to be detected is the same as the next hop of the RIB primary route, the device does not repeatedly create the same type of BFD sessions. Instead, the device reuses the BFD session of other protocols.

Examples

# Enable control-mode BFD for primary link availability detection of IS-IS ECMP routes.

Parameters

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

Usage guidelines

Repeat the command to set the maximum number for different types of records.

If you do not specify the rib nib or routing-table keywords, the command sets the maximum number for all types of RIB next hop and route entry records.

If you do not specify the add, delete, or update keyword, the command sets the maximum number for records that contain the add, delete, and update actions.

Parameters

track-entry-number: Specifies a track entry ID in the range of 1 to 1024.

degrade-cost cost-value: Specifies a cost value to apply to the IPv4 direct routes after the track entry changes to Negative state. The value range for the cost-value argument is 1 to 4294967295.

Usage guidelines

To change the track entry associated with the IPv4 direct routes on an interface, you must first execute the undo route-direct track command to remove the original association. For more information about Track, see High Availability Configuration Guide.

Examples

# Associate the IPv4 direct routes on Ten-GigabitEthernet 0/0/6 with track entry 1 and apply cost 200 to the IPv4 direct routes after the track entry changes to Negative state.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 0/0/6

Parameters

number: Specifies the maximum number of active IPv4/IPv6 routes supported by the device, in the range of 1 to 4294967295.

warn-threshold: Specifies an alarm threshold in the range of 1 to 100, in percentage. When the percentage of active routes exceeds the alarm threshold, the system generates a system log message but still accepts active routes. You can take relevant actions based on the message to save system resources. If the number of active routes reaches the maximum number, no more routes can be added and new routes are discarded.

simply-alert: Enables the device to still accept active routes but generate a log message when the number of active IPv4/IPv6 routes exceeds the maximum number.

Usage guidelines

Configuration in RIB IPv4 address family view limits the number of active IPv4 routes for the public network and all VPN instances.

Configuration in RIB IPv6 address family view limits the number of active IPv6 routes for the public network and all VPN instances.

If you execute this command multiple times in the same view, the most recent configuration takes effect.

Examples

# In RIB IPv4 address family view, set the maximum number of active IPv4 routes to 1000 for the public network and all VPN instances. The device still accepts new active routes but generates a system log message when the maximum number of active routes is exceeded.
