ipv6 nd neighbor-limit

Function

The ipv6 nd neighbor-limit command configures the maximum number of dynamic neighbor entries that can be learned by a specified interface.

The undo ipv6 nd neighbor-limit command restores the default value.

By default, a specified interface can learn a maximum of 1024 dynamic neighbor entries.

Parameters

Parameter	Description	Value
limit-number	The maximum number of dynamic neighbor entries that can be learned by a specified interface.	For USG6630E/6650E, USG6635E/6655E, USG6680E and USG6712E/6716E: the value is an integer ranging from 2 to 4096. For other models: the value is an integer ranging from 2 to 1024.

Usage Guidelines

If an interface learns too many neighbor entries, the processing load for the device will be increased and the performance of the device will be degraded. You can run the ipv6 nd neighbor-limit command to configure the maximum number of dynamic neighbor entries that can be learned by a specified interface.

Example

# Set the maximum number of dynamic neighbor entries that can be learned by the VLANIF100 interface to 10.

<sysname> system-view

[sysname] interface vlanif 100
