Configuring Static Neighbors

Context

To communicate with a destination host, a host needs to obtain the destination host's link-layer address. The link-layer address of a neighbor node can be obtained using the neighbor discovery mechanism, or by manually configuring static neighbor entries. A device identifies a static neighbor entry based on the IPv6 address of this neighbor and number of the Layer 3 interface connected to this neighbor. To filter invalid packets, you can create static neighbor entries, binding the destination IPv6 addresses of these packets to nonexistent MAC addresses.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The specified interface view is displayed.
(Optional) On an Ethernet interface, run undo portswitch
The interface is switched to Layer 3 mode.

By default, an Ethernet interface works in Layer 2 mode.

Only the S5720-EI, S5720-HI, S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-EI, S6720-HI, S6720S-EI, S6730-H, S6730S-H, S6730-S, and S6730S-S support switching between Layer 2 and Layer 3 modes.
Run ipv6 enable
The IPv6 function is enabled.
Run the following commands to configure static neighbors based on the interface type.
- For the Ethernet interface, run the ipv6 neighbor ipv6-address mac-address command.
- For a VLANIF interface, run the ipv6 neighbor ipv6-address mac-address vid vlan-id interface-type interface-number command.
