Configuring a static neighbor entry
A neighbor entry stores information about a link-local node. The entry can be created dynamically
through NS and NA messages, or configured statically.
The device uniquely identifies a static neighbor entry by the IPv6 address and the local Layer 3
interface number of the neighbor. You can configure a static neighbor entry by using one of the
following methods:
• Method 1—Associate a neighbor's IPv6 address and link-layer address with the local Layer 3
interface.
If you use Method 1, the device automatically finds the Layer 2 port connected to the neighbor.
• Method 2—Associate a neighbor's IPv6 address and link-layer address with a Layer 2 port in a
VLAN.
If you use Method 2, make sure the Layer 2 port belongs to the specified VLAN and the
corresponding VLAN interface already exists. The device associates the VLAN interface with
the neighbor IPv6 address to identify the static neighbor entry.
Do not specify a Reth interface as the outgoing interface in IPv6 static neighbor entries if its member
interfaces contain subinterfaces. For more information about Reth interfaces, see High Availability
Configuration Guide.
To configure a static neighbor entry:
Step Command Remarks
1. Enter system view.

N/A
2. Configure a static
neighbor entry.

{ vlan-id port-type port-number |

By default, no static neighbor
entries exist.
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.

N/A
2. Enter interface view.

3. Set the maximum number of
dynamic neighbor entries that
the interface can learn.

By default, the maximum number of
dynamic neighbor entries that the
interface can learn is as follows:
• MSR954
(JH296A/JH297A/JH298A/JH2
99A/JH373A)/
MSR958(JH300A/JH301A):
2048.
• MSR2003: 2048.
• MSR2004-24/2004-48: 2048.
