·          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 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 entry with the 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 with a mask not greater than the entered subnet mask, the entry with the longest mask length is 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.

Max ECMP: 32

Max Active Route: 262144

Remain Active Route: 262134

Threshold value of active routes alert: 65100

Table 4 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

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.

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

This command applies to a device that provides the same physical output interface for large numbers of routes, including ECMP routes and primary/secondary routes. When a link failure occurs on the interface, the device must perform the following tasks before switching the traffic to another route:

1.        Deletes all ARP entries for the link.

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

This procedure is time consuming and interrupts traffic for a long time. To resolve this problem, you can enable route fast switchover. This feature allows the device to first instruct the FIB to delete the invalid FIB entries for route switchover.

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.

Syntax

ipv6 route fast-switchover enable

undo ipv6 route fast-switchover enable

Default

IPv6 route fast switchover is disabled.

Usage guidelines

This command applies to a device that provides the same physical output interface for large numbers of routes, including ECMP routes and primary/secondary routes. When a link failure occurs on the interface, the device must perform the following tasks before switching the traffic to another route:

1.        Deletes all ND entries for the link.

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

This procedure is time consuming and interrupts traffic for a long time. To resolve this problem, you can enable route fast switchover. This feature allows the device to instruct the FIB to delete the invalid FIB entries for route switchover first.

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.

<Sysname> system-view

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.

Examples

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

<Sysname> system-view

[Sysname] rib

[Sysname-rib] address-family ipv4

[Sysname-rib-ipv4] protocol static nexthop recursive-lookup route-policy policy1
