that an interface can dynamically learn. When the number of dynamically learned neighbors reaches
the threshold, the interface stops learning neighbor information.
To configure the maximum number of neighbors dynamically learned:
Step
1.
Enter system view.
2.
Enter interface view.
3.
Configure the maximum
number of neighbors
dynamically learned by an
interface.
Setting the age timer for ND entries in stale state
ND entries in stale state have an age timer. If an ND entry in stale state is not refreshed before the timer
expires, it transits to the delay state. If it is still not refreshed in five seconds, the ND entry transits to the
probe state, and the device sends an NS message for detection. If no response is received, the device
removes the ND entry.
To set the age timer for ND entries in stale state:
Step
1.
Enter system view.
2.
Set the age timer for ND
entries in stale state.
Configuring parameters related to RA messages
You can enable an interface to send RA messages, and configure the interval for sending RA messages
and parameters in RA messages. After receiving an RA message, a host can use these parameters to
perform corresponding operations.

Description
When sending an IPv6 packet, a host uses the value to fill the Hop Limit field in IPv6
headers. The value is also filled into the Hop Limit field in the response packet of a
device.
After receiving the prefix information, the hosts on the same link can perform
stateless autoconfiguration.
Guarantees that all nodes on a link use the same MTU value.
