ipv6 fast-forwarding load-sharing

Use ipv6 fast-forwarding load-sharing to enable IPv6 fast forwarding load sharing.

Use undo ipv6 fast-forwarding load-sharing to disable IPv6 fast forwarding load sharing.

Syntax

ipv6 fast-forwarding load-sharing

Usage guidelines

IPv6 fast forwarding load sharing enables the device to load share packets of the same flow. This feature identifies a data flow by using the packet information.

If IPv6 fast forwarding load sharing is disabled, the device identifies a data flow by the packet information and the input interface. No load sharing is implemented.

Examples

# Enable IPv6 fast forwarding load sharing.

<Sysname> system-Views

[Sysname] ipv6 fast-forwarding load-sharing

reset ipv6 fast-forwarding cache

Use reset ipv6 fast-forwarding cache to clear the IPv6 fast forwarding table.

Syntax

In standalone mode:

reset ipv6 fast-forwarding cache

In IRF mode:

reset ipv6 fast-forwarding cache [ slot slot-number ]

Views

Parameters

slot slot-number: Specifies an IRF member device by its member ID. If you do not specify a member device, this command clears the IPv6 fast forwarding table for all member devices. (In IRF mode.)

Examples

# Clear the IPv6 fast forwarding table.

<Sysname> reset ipv6 fast-forwarding cache
