Setting the maximum number of dynamic neighbor entries
The device can dynamically acquire the link-layer address of a neighboring node through NS and NA messages and add it into the neighbor table. When the number of dynamic neighbor entries reaches the threshold, the interface stops learning neighbor information. To prevent an interface from occupying too many neighbor table resources, you can set the maximum number of dynamic neighbors that an interface can learn.
To set the maximum number of dynamic neighbor entries:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter interface view. | interface interface-type interface-number | N/A |
3. Set the maximum number of dynamic neighbor entries that the interface can learn. | ipv6 neighbors max-learning-num max-number | By default, an interface can learn a maximum of 4096 dynamic neighbor entries. |
