neighbors, in the range from 0 to the number
supported by the device. 0 indicates the number is not
limited.
Interface configuration mode
This function can prevent neighbor entries generated by malicious neighbor attacks from consuming
memory. limit must be no smaller than the number of neighbors learned on the interface. Otherwise,
the configuration does not take effect.
The following example sets the number of neighbors learned on the interface to 100.
Ruijie(config)# interface GigabitEthernet 0/1
Ruijie(config-if-GigabitEthernet 0/1)# ipv6 nd cache interface-limit 100
3.10 ipv6 nd dad attempts
Use this command to set the number of the NS packets to be continuously sent for IPv6 address
collision check on the interface. Use the no form of this command to restore it to the default setting.
ipv6 nd dad attempts value
no ipv6 nd dad attempts value
Number of the NS packets. If it is set to 0, it indicates that the IPv6
address collision check is disabled on the interface. The range is 0 to 600.
Interface configuration mode.
When the interface is configured with a new IPv6 address, the address collision shall be checked
before the address is assigned to the interface, and the address shall be in the ”tentative” status. After
the address collision check is completed, if no collision is detected, the address can be used
normally; if collision is detected and the interface ID of the address is an EUI-64 ID, it indicates that
