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

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

The system displays active route entries with destinations in the range of ip-address1/32 to ip-address2/32.

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 brief routing table information for the public network.

Examples

# Display brief routing table information for the public network.

<Sysname> display ip routing-table summary

 

Max ECMP: 32

Max Active Route: 262144

Remain Active Route: 262126

# Display brief routing table information for the MPLS L3VPN instance vpn1.

<Sysname> display ip routing-table vpn-instance vpn1 summary

 

Max ECMP: 32

Max Active Route: 262144

Remain Active Route: 262134

Threshold value percentage of max active routes: 100%

Table 6 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

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.

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.

Parameters

per-flow: Implements per-flow load sharing.

level level-number: Specifies an algorithm level. The value for the level-number argument can be 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.

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 dest-ip and src-ip keywords are specified in pairs.

·     If you specify the dest-ip keyword, this command automatically adds the src-ip keyword.

·     If you specify the src-ip keyword, this command automatically adds the dest-ip keyword.

The src-port and dest-port keywords are specified in pairs.

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

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.

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 BGP routes.
