Basic IP forwarding commands

display fib

Use display fib to display FIB entries.

Syntax

display fib  [ ip-address [ mask | mask-length ] ]

Views

Any view

network-operator

Parameters

ip-address: Displays the FIB entry that matches the specified destination IP address.

mask: Specifies the mask for the IP address.

mask-length: Specifies the mask length for the IP address. The value range is 0 to 32.

Usage guidelines

If you specify an IP address without a mask or mask length, this command displays the longest matching FIB entry.

If you specify an IP address and a mask or mask length, this command displays the exactly matching FIB entry.

Examples

# Display all FIB entries of the public network.

<Sysname> display fib

Destination count: 5 FIB entry count: 5

Table 1 Command output

Load sharing commands

bandwidth-based-sharing

Use bandwidth-based-sharing to enable IPv4 load sharing based on bandwidth.

Use undo bandwidth-based-sharing to disable IPv4 load sharing based on bandwidth.

Syntax

bandwidth-based-sharing

undo bandwidth-based-sharing

Default

The IPv4 load sharing based on bandwidth is disabled.

Predefined user roles

network-admin

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 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

ip load-sharing mode

Use ip load-sharing mode to configure the load sharing mode.

Use undo ip load-sharing mode to restore the default.

Syntax

ip load-sharing mode { per-flow [ dest-ip | dest-port | ip-pro | src-ip | src-port ] * | per-packet } global

undo ip load-sharing mode global

Default

The device performs per-flow load sharing.

Parameters

per-flow: Implements per-flow load sharing.

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.

per-packet: Implements per-packet load sharing.

Usage guidelines

The per-packet load sharing mode does not take effect in fast forwarding.

Examples

# Configure per-flow load sharing.

<Sysname> system-view

[Sysname] ip load-sharing mode per-flow global
