Setting an Aging Time for Neighbor Entries in the Stale State

This section describes how to set an aging time for neighbor entries in the stale state. A short aging time allows the device to delete neighbor entries in the stale state quickly.

Procedure

Set an aging time for a neighbor entry in the stale state in the system view.
1. Access the system view.
```
system-view
```
2. Set the aging time for a neighbor entry in the stale state.
```
ipv6 nd stale-timeout timeout-value
```
  The default aging time of neighbor entries in the stale state is 1200s in the system view.
Set an aging time for a neighbor entry in the stale state in the interface view.
1. Access the system view.
```
system-view
```
2. Access the interface view.
```
interface interface-type interface-number
```
3. Set the aging time for a neighbor entry in the stale state on the interface.
```
ipv6 nd stale-timeout timeout-value
```
  By default, no aging time is set for neighbor entries in the stale state in the interface view, and all interfaces use the global configuration.
