Use the undo ipv6 neighbor command to remove a static neighbor entry. 

You can use a Layer 3 VLAN interface or a Layer 2 port in the VLAN to configure a static neighbor entry. 

z 

If the first method is used, the neighbor entry is in the INCMP state. After the device obtains the 

corresponding Layer 2 port information through resolution, the neighbor entry will go into the 

REACH state. 

z 

If the second method is used, the corresponding VLAN interface must exist and the port specified 

by port-type port-number must belong to the VLAN specified by vlan-id. After the static neighbor 

entry is configured, the device will relate the VLAN interface with the IPv6 address to identify the 

static neighbor entry uniquely and the entry will be in the REACH state. 

To remove a static neighbor entry, you only need to specify the corresponding VLAN interface and the 

neighbor address.

number: Maximum number of neighbors that can be dynamically learned by the interface, in the range 

of 1 to 2048. 

Use the ipv6 neighbors max-learning-num command to configure the maximum number of neighbors 

that can be dynamically learned on the interface. 

Use the undo ipv6 neighbors max-learning-num command to restore the default. 

By default, the maximum number of neighbors that can be dynamically learned on an interface is 2048.  

# Set the maximum number of neighbors that can be dynamically learned on VLAN-interface 100 to 10.
