Configuring a static neighbor entry
About static neighbor entries
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 using the neighbor's IPv6 address and the
number of the Layer 3 interface that connects to 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.
• Method 2—Associate a neighbor's IPv6 address and link-layer address with a Layer 2 port in a
VLAN.
Restrictions and guidelines
You can use either of the methods to configure a static neighbor entry for a VLAN interface.
• If you use Method 1, the device is required to resolve the Layer 2 port in the related VLAN.
• If you use Method 2, make sure the Layer 2 port belongs to the specified VLAN and the
corresponding VLAN interface already exists. After the configuration, the device associates the
VLAN interface with the neighbor IPv6 address to identify the static neighbor entry.
Procedure
1. Enter system view.
system-view
2. Configure a static neighbor entry.
ipv6 neighbor ipv6-address mac-address { vlan-id port-type
port-number | interface interface-type interface-number }
By default, no static neighbor entries exist.
Setting the dynamic neighbor learning limit on an
interface
About the dynamic neighbor learning limit on an interface
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 limit, the interface stops learning neighbor information.
This feature limits the neighbor table size. A large neighbor table will degrade the forwarding
performance.
Procedure
1. Enter system view.
system-view
2. Enter interface view.
interface interface-type interface-number
3. Set the dynamic neighbor learning limit on the interface.
