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 displays routing information for the public network.
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

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. |

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

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.

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

Parameters
protocol: Specifies a routing protocol.
instance instance-name: Specifies a BGP instance by its name, a case-sensitive string of 1 to 31 characters. This argument applies only to the BGP protocol. If you do not specify a BGP instance, this command sets the maximum lifetime for all BGP routes and labels in the RIB.
seconds: Specifies the maximum lifetime for routes and labels in the RIB, in the range of 1 to 6000 seconds.
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 RIP routes and labels in the RIB to 60 seconds.

protocol nexthop recursive-lookup
Use protocol nexthop recursive-lookup to configure routing policy-based recursive lookup.
Use undo protocol nexthop recursive-lookup to remove the configuration.
Syntax
protocol protocol nexthop recursive-lookup route-policy route-policy-name
undo protocol protocol nexthop recursive-lookup route-policy
Default
Routing policy-based recursive lookup is not configured.

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.

Parameters
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters.
all-routes: Clears route statistics for the public network and all VPN instances.
all-vpn-instance: Clears route statistics for all VPN instances.
protocol: Clears route statistics for a routing protocol.
all: Clears route statistics for all IPv4 routing protocols.
Usage guidelines
This command clears IPv4 route statistics for the public network if you do not specify the all-routes, vpn-instance, or all-vpn-instance keyword.
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 }
reset ipv6 routing-table [ all-routes | all-vpn-instance ] statistics protocol { protocol | all }

Parameters
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters.
all-routes: Clears route statistics for the public network and all VPN instances.
all-vpn-instance: Clears route statistics for all VPN instances.
protocol: Clears route statistics for an IPv6 routing protocol.
all: Clears route statistics for all IPv6 routing protocols.
Usage guidelines
This command clears IPv6 route statistics for the public network if you do not specify the all-routes, vpn-instance, or all-vpn-instance keyword.
Examples
# Clear all IPv6 route statistics for the public network.
<Sysname> reset ipv6 routing-table statistics protocol all

routing-table limit
Use routing-table limit to set the maximum number of active IPv4/IPv6 routes supported by the device.
Use undo routing-table limit to restore the default.
Syntax
routing-table limit number { warn-threshold | simply-alert }
undo routing-table limit
Default
The maximum number of active IPv4/IPv6 routes is not set for the device.

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.
