Usage guidelines
This feature load shares flow traffic among multiple output interfaces based on their load percentages. The device calculates the load percentage for each output interface in terms of their expected bandwidths.
Devices that run load sharing protocols, such as Locator/ID Separation Protocol (LISP), implement load sharing based on the ratios defined by these protocols.
Examples
# Enable IPv4 load sharing based on bandwidth.
<Sysname> system-view
[Sysname] bandwidth-based-sharing

Parameters
ingress-port interface-type interface-number: Specifies an ingress port by its type and number.
packet-format { ipv4oe dest-ip ip-address [src-ip ip-address ] | ipv6oe dest-ipv6 ipv6-address [ flow-label flow-label | src-ipv6 ipv6-address ] * }: Specifies the packet encapsulation format.
· ipv4oe: Specifies the format of IPv4 over Ethernet.
· dest-ip ip-address: Specifies the destination IPv4 address in dotted decimal notation. If you do not specify this argument, the calculation uses 0.0.0.0 for path selection.
· src-ip ip-address: Specifies the source IPv4 address in dotted decimal notation. If you do not specify this argument, the calculation uses 0.0.0.0 for path selection.
· ipv6oe: Specifies the format of IPv6 over Ethernet.
· dest-ipv6 ipv6-address: Specifies the destination IPv6 address. If you do not specify this option, the calculation uses 0:0:0:0:0:0:0:0 for path selection.
· flow-label flow-label: Specifies the flow label of IPv6 packets. The value range for the flow-label argument is 0 to 1048575. If this parameter is not specified, the device uses a flow label value of 0 for ECMP route selection.
· src-ipv6 ipv6-address: Specifies the source IPv6 address. If you do not specify this option, the calculation uses 0:0:0:0:0:0:0:0 for path selection.
dest-port port-id: Specifies a destination port number in the range of 1 to 65535. If you do not specify this option, the calculation uses 0 for path selection.
ip-pro protocol-id: Specifies an IP protocol by its number in the range of 1 to 65535. If you do not specify this option, the calculation uses 0 for path selection.
source-port port-id: Specifies a source port number in the range of 1 to 65535. If you do not specify this option, the calculation uses 0 for path selection.
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. To display the path on the public network, do not specify this option.
Usage guidelines
The option settings in this command must match both the options displayed in the display ip load-sharing mode command and the field values in load shared packets. If the option settings do not meet the requirement, the path displayed by this command might be different from the real path for load sharing.
Examples
# Display the load sharing path selected for the flow with the following attributes: ingress port HundredGigE 1/0/3, destination IP address 10.110.0.2, source IP address 10.100.0.2, IP protocol number 153, destination port number 2000, source port number 2000.

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 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.

|
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 of next hops issued by the IPv6 RIB to the FIB.
receive: Displays the records of next hop operations performed by the IPv6 RIB upon reception of data from routing protocols.
add: Displays the records of added next hops.
delete: Displays the records of deleted next hops.
update: Displays the records of updated next hops. If you specify the flush keyword, records of added next hops are counted into records of updated next hops.
verbose: Displays detailed information about next hop operation records. If you do not specify this keyword, the command displays only brief information about next hop operation records.
Usage guidelines
If you do not specify the add, delete, or update keyword, the command displays the records of added, deleted, and updated next hops.
When a minor (level-1) memory alarm is present, the system does not generate next hop operation records. When a critical (level-3) memory alarm is triggered, the system clears existing next hop operation records. When the minor memory alarm is cleared, the system starts recording new next hop operations 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 displays routing information for the public network.
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.
verbose: Displays detailed routing table information, including information about both active and inactive routes. If you do not specify this keyword, the command displays only brief information about active routes.
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.

display rib nib record
Use display rib nib record to display next hop operation records for the RIB.
Syntax
display rib nib record flush [ delete | update ] [ verbose ]
display rib nib record receive [ add | delete | update ] [ verbose ]
Views
Any view
Predefined user roles
network-admin
network-operator
Parameters
flush: Displays the records of next hops issued by the RIB to the FIB.
receive: Displays the records of next hops received by the RIB from routing protocols.
add: Displays the records of added next hops.
delete: Displays the records of deleted next hops.
update: Displays the records of updated next hops. If you specify the flush keyword, records of added next hops are counted into records of updated next hops.
verbose: Displays detailed information about next hop operation records. If you do not specify this keyword, the command displays only brief information about next hop operation records.
Usage guidelines
If you do not specify the add, delete, or update keyword, the command displays the records added, deleted, and updated next hops.
When a minor (level-1) memory alarm is present, the system does not generate next hop operation records. When a critical (level-3) memory alarm is triggered, the system clears existing next hop operation records. When the minor memory alarm is cleared, the system starts recording new next hop operations 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.

Default
The device performs per-flow load sharing based on the following criteria: source IP address, destination IP address, source port number, destination port number, and IP protocol number.
Views
System view
Predefined user roles
network-admin
Parameters
per-flow: Implements per-flow load sharing.
level level-number: Specifies an algorithm level. The level-number argument can be set to 2 or 3. If you do not specify an algorithm level, the algorithm level is 1.
algorithm algorithm-number: Specifies an algorithm by its number for per-flow load sharing. The value range for the algorithm-number argument is 0 to 15. As a best practice, select a value in the range of 0 to 9. Values in the range of 10 to 15 are used in specific test environments. If you do not specify an algorithm, the default algorithm is algorithm 0.
seed seed-number: Specifies the seed value for the algorithm. The value range for the seed-number argument is 0 to FFFF.
shift shift-number: Specifies the shift value for the hash algorithm result. The value range for the shift-number argument is 0 to 15 and the default value is 0.
dest-ip: Identifies flows by destination IP address.
dest-port: Identifies flows by destination port.
flow-label: Identifies IPv6 flows by flow label. This keyword takes effect only on IPv6 traffic.
ip-pro: Identifies flows by protocol number.
src-ip: Identifies flows by source IP address.
src-port: Identifies flows by source port.
global: Configures the load sharing mode globally.
slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command configures the load sharing mode for all cards.
Usage guidelines
If traffic is not load shared well among interfaces, you can use the seed seed-number and shift shift-number options to adjust the algorithm result.
The following information applies when symmetric load sharing is enabled:
· The dest-ip and src-ip keywords are always used in pairs for load sharing.
¡ If you specify the dest-ip keyword, this command automatically specifies the src-ip keyword.
¡ If you specify the src-ip keyword, this command automatically specifies the dest-ip keyword.
· The src-port and dest-port keywords are always used in pairs for load sharing.
¡ If you specify the dest-port keyword, this command automatically specifies the src-port keyword.
¡ If you specify the src-port keyword, this command automatically specifies the dest-port keyword.
This command and the link-aggregation load-sharing mode command are mutually exclusive. If both commands are configured, the most recent configuration takes effect. For more information about the link-aggregation load-sharing mode command, see Ethernet link aggregation configuration in Layer 2—LAN Switching Configuration Guide.
Examples
# Configure per-flow load sharing for slot 1.
<Sysname> system-view
[Sysname] ip load-sharing mode per-flow slot 1
ip load-sharing symmetric 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.
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
ipv6 route-direct track
Use ipv6 route-direct track to associate the IPv6 direct routes on an interface with a track entry and apply a cost value to the IPv6 direct routes after the track entry changes to Negative state.

Predefined user roles
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 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 IPv6 direct routes on an interface, you must first execute the undo ipv6 route-direct track command to remove the original association. For more information about Track, see High Availability Configuration Guide.
Examples
# Associate the IPv6 direct routes on HundredGigE 1/0/1 with track entry 1 and apply cost 200 to the IPv6 direct routes after the track entry changes to Negative state.

Usage guidelines
Maintenance probe (MTP) helps troubleshoot routing protocol issues. It enables the device to automatically perform the following operations upon expiration of a neighbor's hold timer:
1. Ping the neighbor or trace the route to the neighbor.
2. Record the ping or tracert results.
To view data generated by MTP for a routing protocol, execute the troubleshooting commands for that routing protocol. For example, execute the display bgp troubleshooting command for BGP. To view detailed data generated by MTP, use the display logbuffer command.

Parameters
clear-interval interval: Specifies the interval for clearing the recursion loop counter, in the range of 1 to 65535 seconds.
Usage guidelines
Recursion loop suppression 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. When the suppression time expires, the system resets the counter and disables route recursion suppression.
Examples
# Set the interval for clearing the recursion loop counter to 100 seconds.

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.

# Disable the suppression for next hop recursion loop.

Syntax
primary-path-detect bfd { ctrl | echo } [ inter-protocol-frr | protocol-ecmp protocol ]
undo primary-path-detect bfd [ inter-protocol-frr | protocol-ecmp protocol ]
Default
BFD is not enabled to do quick next hop unreachability detection on the primary route for inter-protocol FRR or ECMP.

Parameters
ctrl: Specifies the BFD control packet mode.
echo: Specifies the BFD echo packet mode.
inter-protocol-frr: Specifies inter-protocol FRR.
protocol-ecmp protocol: Specifies 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 BFD to detect next hop unreachability of the primary route for quick switchover to the backup route by establishing an IPFRR-type BFD session.
· 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 you configure FRR for a routing protocol, the device uses 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 do detection on these backup ECMP routes.
This command enables the device to create a BFD session for a route only if it already has a backup next hop.
You can repeat this command to change the BFD mode (echo packet mode or control packet mode).
The following information applies if you execute this command or its undo form without the inter-protocol-frr or protocol-ecmp keyword:
· The command or its undo form applies to both inter-protocol FRR and ECMP routes.
· To change or remove the configuration, you can only use the command or its undo form without the inter-protocol-frr or protocol-ecmp keyword.
For example, if you have executed the primary-path-detect bfd ctrl command, you can use only the following commands to modify or remove the configuration, respectively:
¡ primary-path-detect bfd echo.
¡ undo primary-path-detect bfd.
In control packet mode, two ends of a connection must negotiate to establish a BFD session. If you use BFD control packet mode for detection, you must manually create a static BFD session on the next hop as follows for a successful BFD session establishment:
· Configure the static BFD session for single-hop detection.
· Use the destination and source IP addresses of the BFD session automatically created on the device as the source and destination IP addresses of the session, respectively.
· Set the remote discriminator to be the same as the local discriminator of the BFD session automatically created on the device.
For more information about creating a static BFD session, see BFD configuration in High Availability Configuration Guide.
Service modules (for example, BGP, OSPF, and IS-IS) other than the RIB module might also create BFD sessions to detect next-hop unreachability on the primary route. The device does not create two identical BFD sessions of the same type for different service modules. If the BFD session to be established for RIB is identical to an existing same-type BFD session, the device reuses the existing one.
Examples
# Enable control-mode BFD for next hop unreachability detection on 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.

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

Parameters
limit: Sets the maximum number of RIB operation records by operation type. The value range is 0 to 1000000. To disable recording a type of RIB operation, set the value to 0. When the record limit for a type of operation is reached, the device continues to record new operations of that type. The new records will overwrite the earliest records.
rib nib: Sets the maximum number of records for a type of next hop operation on the RIB.
routing-table: Sets the maximum number of records for a type of route entry operation on the RIB.
flush: Sets the maximum number of records for a type of operation flushed by the RIB to the FIB.
notify: Sets the maximum number of records for a type of operation reported by the RIB to routing protocols.
receive: Sets the maximum number of records for a type of operation performed by the RIB upon reception of data from routing protocols.
add: Sets the maximum number of add operation records.
update: Sets the maximum number of update operation records. If you specify the flush or notify keyword, add operation records are counted into update operation records.
delete: Sets the maximum number of delete operation records.
Usage guidelines
Repeat the command to set the maximum number of records for different types of RIB operations.
To set the same limit on the records for all types of RIB operations in bulk, execute the command without the rib nib or routing-table keyword.
To set the same limit for add, delete, and update operation records in bulk, execute the command without specifying the add, delete, or update keyword.
