· 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.

Threshold value percentage of max active routes: 100%

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 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 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.

Syntax

display ipv6 rib nib record flush [ delete | update ] [ verbose ]

display ipv6 rib nib record receive [ add | delete | update ] [ verbose ]

Views

Any view

Predefined user roles

network-admin

network-operator

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.

· 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.

Parameters

ignore-preference: Allows routes with different preferences to form ECMP routes. If you do not specify this keyword, only routes with the same preference can form ECMP routes.

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 routes from different protocols in the public network to form ECMP routes.

Usage guidelines

By default, routes from different protocols have different preferences, and the route costs are calculated in different ways. Such routes cannot form ECMP routes. Configure this command to ignore the costs for routes from different protocols, so that they can form ECMP routes.

For routes from multiple protocols with the same destination to form ECMP routes, follow these restrictions and guidelines:

· If you do not specify the ignore-preference keyword, routes with the highest priority will form ECMP routes. You can edit the preferences for routes from different protocols to the same value, so that they can form ECMP routes.

· If you specify the ignore-preference keyword, multiple routes will form ECMP routes.

If you configure both this command and the inter-protocol fast-reroute command, only this command takes effect.

Parameters

ecmp-shared: Specify a shared next hop for ECMP routes. Multiple ECMP routes use the same backup next hop. If you do not specify this keyword, the device performs backup next hop calculation for only non-ECMP routes.

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.

If you specify the ecmp-shared keyword, the device calculates a shared backup next hop for multiple ECMP routes with the same destination. This backup next hop is from a different protocol than the ECMP routes. When all next hops of the ECMP routes fail, RIB replaces them with the backup next hop, and issues the backup next hop to the FIB as an ECMP route. You can view the detailed route information with the display ip routing-table command. The route with the Backup state in the output indicates the backup next hop. If the backup next hop is the same as a next hop of an ECMP route, RIP will not issue the backup next hop to the FIB. In this case, the backup next hop will not take effect.

If you configure both this command and the inter-protocol ecmp command, this command will not take effect.

network-admin

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 IPv6 direct route after the track entry changes to Negative state. The value range for the cost-value argument is 1 to 4294967295.

Usage guidelines

On a network where an IPv6 VRRP group is used as the default gateway, upstream traffic is always forwarded through the master device in the IPv6 VRRP group. The corresponding downstream traffic might take a different path because the route selection is determined by the configured dynamic routing protocol. The mismatching forwarding paths might cause the traffic to be blocked by firewalls (if configured), and increase the complexity and overhead for traffic monitoring and statistics collection operations.

You can resolve the issue by configuring IPv6 direct route-Track-IPv6 VRRP collaboration. The collaboration ensures that the upstream traffic and the corresponding downstream traffic are forwarded through matching paths (both through the master device in the IPv6 VRRP group).

To configure IPv6 direct route-Track-IPv6 VRRP collaboration, perform the following tasks on each member device of the IPv6 VRRP group:

1. Create a track entry associated with the IPv6 VRRP group member device so the track entry state changes according to the status of the device in the IPv6 VRRP group.

¡ If the device state is Backup or Initialize, the track entry state changes to Negative.

¡ If the device state is Master, the track entry state changes to Positive.

¡ If the device state is Inactive or the IPv6 VRRP group does not exist, the track entry state changes to NotReady.

2. Associate the track entry with the IPv6 direct route on the interface connected to the downstream device. The cost value of the IPv6 direct route on the interface changes according to the status of the track entry.

¡ If the track entry does not exist or the track entry is in NotReady or Positive state, the cost of the IPv6 direct route changes to 0.

¡ If the track entry is in Negative state, the cost of the IPv6 direct route changes to the value configured by using the ipv6 route-direct track command.

IMPORTANT:

The IPv6 direct route that has a lower cost value is preferentially used.

3. Enable IPv6 direct route redistribution on the IPv6 VRRP group member device for the dynamic routing protocol.

For more information about associating Track with an IPv6 VRRP group, see Track configuration in High Availability Configuration Guide.

The IPv6 direct route on an interface can be associated only with one track entry. To change the track entry associated with the IPv6 direct route on an interface, you must first execute the undo ipv6 route-direct track command to remove the original association.

Examples

# Associate track entry 1 with the IPv6 direct route on Ten-GigabitEthernet 3/1/1 and apply cost 200 to the IPv6 direct route after the track entry changes to Negative state.

Parameters

maximum-interval: Specifies the maximum suppression timer in the range of 1 to 60 seconds.

minimum-interval: Specifies the minimum suppression timer in the range of 10 to 60000 milliseconds. The default value is 50.

incremental-interval: Specifies the incremental timer in the range of 10 to 60000 milliseconds. The default value is 200.

millisecond interval: Specifies a fixed suppression timer in the range of 10 to 10000 milliseconds.

Usage guidelines

A change of a related route or tunnel obtained through nexthop recursion triggers another recursion for the recursive route. When the network changes frequently, the route recursion is performed repeatedly, which causes high CPU usage. To solve this issue, use this command for the RIB to wait for the suppression timer to expire before obtaining the recursion result. In this way, the route recursion is performed less often and the CPU usage can be reduced. However, this command can result in lower route recursion efficiency and slow route convergence. Use this command as needed make sure the parameters are appropriate.

After you use this command, no matter how the route recursion results change within the suppression timer, the RIB always obtains the most recent results after the suppression timer expires.

To dynamically suppress route recursion, configure at least the maximum suppression timer. If the route recursion results keep changing, the suppression time increases until the maximum suppression timer expires or the recursion results stop changing.

The dynamic suppression time (T) is calculated based on the number of route recursions (N), as follows:

· When N = 1, T = minimum-interval.

· When N ≥ 2, T = minimum-interval + incremental-interval × [ 2 ^ ( N - 2 ) ], and T ≤ maximum-interval.

· When T reaches maximum-interval for three consecutive times, T = minimum-interval in the next recursion, and N becomes 1.

· If the recursion results have not changed in two times the maximum-interval, T = minimum-interval in the next recursion, and N becomes 1.

The value for the minimum-interval or incremental-interval argument cannot be greater than that for the maximum-interval argument.

The suppression timer settings apply to only the next route recursion.

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

The actual suppression timer equals the sum of the suppression timer configured in this command and the timer configured in any of the following commands:

· nexthop recursive-lookup restrain (BGP instance view/BGP-VPN instance view)

· nexthop recursive-lookup delay (BGP address family view)

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: Detects the next hop availability of the primary route for inter-protocol FRR.

protocol-ecmp protocol: Detects the next hop availability of the primary route 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

This command enables the device to automatically create an IPFRR type of BFD session. The device uses this BFD session to detect the next hop availability of the primary route to speed traffic switchover when the next hop of the primary route fails.

· 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 can take effect and automatically establish the IPFRR type of BFD session only when a primary route exists and the primary route has backup next hops.

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.

When you use a BFD session in control packet mode to detect the next hop availability of the primary route, you must manually create a static BFD session on the next hop device. The reason is that the BFD session in control packet mode requires negotiation of both ends for successful establishment. The local device can use the BFD session in control packet mode to detect the next hop availability of the primary route only when the static BFD session created on the next hop device of the primary route meets the following requirements:

· The static BFD session is a single-hop BFD session in control packet mode.

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

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

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

For more information about static BFD session creation, see BFD configuration in High Availability Configuration Guide.

When service modules other than RIB, for example, BGP, OSPF, or IS-IS, use BFD to detect the next hop availability of the primary route, they also automatically create a BFD session. If the BFD session automatically created by these service modules detects the availability of the same next hop as RIB, the device does not automatically create the same type of BFD session for RIB. Instead, RIB will use the existing BFD session.

Examples

# Use BFD in control packet mode to detect the next hop availability of the primary route for 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.

The routing policy does not apply to routes received from directly connected BGP neighbors.

route-direct track

Use route-direct track to associate a track entry with the IPv4 direct route on an interface and apply a cost value to the IPv4 direct route after the track entry changes to Negative state.

Use undo route-direct track to restore the default.

Syntax

route-direct track track-entry-number degrade-cost cost-value

undo route-direct track

Default

No track entry is associated with the IPv4 direct route on an interface.

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 route after the track entry changes to Negative state. The value range for the cost-value argument is 1 to 4294967295.

Usage guidelines

On a network where an IPv4 VRRP group is used as the default gateway, upstream traffic is always forwarded through the master device in the IPv4 VRRP group. The corresponding downstream traffic might take a different path because the route selection is determined by the configured dynamic routing protocol. The mismatching forwarding paths might cause the traffic to be blocked by firewalls (if configured), and increase the complexity and overhead for traffic monitoring and statistics collection operations.

You can resolve the issue by configuring IPv4 direct route-Track-IPv4 VRRP collaboration. The collaboration ensures that the upstream traffic and the corresponding downstream traffic are forwarded through matching paths (both through the master device in the IPv4 VRRP group).

To configure IPv4 direct route-Track-IPv4 VRRP collaboration, perform the following tasks on each member device of the IPv4 VRRP group:

1. Create a track entry associated with the IPv4 VRRP group member device so the track entry state changes according to the status of the device in the IPv4 VRRP group.

¡ If the device state is Backup or Initialize, the track entry state changes to Negative.

¡ If the device state is Master, the track entry state changes to Positive.

¡ If the device state is Inactive or the IPv4 VRRP group does not exist, the track entry state changes to NotReady.

2. Associate the track entry with the IPv4 direct route on the interface connected to the downstream device. The cost value of the IPv4 direct route on the interface changes according to the status of the track entry.

¡ If the track entry does not exist or the track entry is in NotReady or Positive state, the cost of the IPv4 direct route changes to 0.

¡ If the track entry is in Negative state, the cost of the IPv4 direct route changes to the value configured by using the route-direct track command.

IMPORTANT:

The IPv4 direct route that has a lower cost value is preferentially used.

3. Enable IPv4 direct route redistribution on the IPv4 VRRP group member device for the dynamic routing protocol.

The IPv4 direct route on an interface can be associated only with one track entry. To change the track entry associated with the IPv4 direct route on an interface, you must first execute the undo route-direct track command to remove the original association.

Examples

# Associate track entry 1 with the IPv4 direct route on Ten-GigabitEthernet 3/1/1 and apply cost 200 to the IPv4 direct route after the track entry changes to Negative state.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 3/1/1

[Sysname-Ten-GigabitEthernet3/1/1] route-direct track 1 degrade-cost 200
