Setting The Maximum Number Of Dynamic Neighbor Entries; Setting The Aging Timer For Nd Entries In Stale State - H3C MSR 2600 Configuration Manual

If you use Method 2, make sure the corresponding VLAN interface exists and the Layer 2 port
specified by port-type port-number belongs to the VLAN specified by vlan-id. The device associates
the VLAN interface with the neighbor IPv6 address to identify the static neighbor entry.
To configure a static neighbor entry:
Step
1. Enter system view.
2. Configure a static
neighbor entry.

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
1. Enter system view.
2. Enter interface view.
3. Set the maximum number of
dynamic neighbor entries that
the interface can learn.

Setting the aging timer for ND entries in stale state

ND entries in stale state have an aging timer. If an ND entry in stale state is not refreshed before the timer
expires, the ND entry changes to the delay state. If it is still not refreshed in 5 seconds, the ND entry
changes to the probe state, and the device sends an NS message three times. If no response is received,
the device removes the ND entry.
To set the aging timer for ND entries in stale state:
Step
1. Enter system view.
2. Set the aging timer for ND
entries in stale state.
