35.1.5 NDP
The formats and settings of NDP frames sent by the Switch conform to RFC4861.
- <Structure of this section>
(1) NDP entry-deletion criteria
If an NDP entry satisfies any of the condition below, that entry is deleted. (Note, however, that static NDP entries specified in the configuration are not deleted.)
-
The communication with the IPv6 address indicated in the NDP entry has stopped and 10 minutes have elapsed.
-
When the communication with the IPv6 address indicated in the NDP entry in stale status is resumed, the neighbor is no longer reachable.
-
All NDP entries indicate neighbors that exist on interfaces that are down.
(2) Configuring Static NDP
To connect the Switch to a product that does not use NDP, use the ipv6 neighbor configuration command to associate Ethernet MAC addresses and IPv6 addresses (static NDP information).
(3) Viewing NDP Info
You can execute the show ipv6 neighbors command on an operation terminal to check NDP information. By checking NDP information, you can determine the association between the IPv6 address and the MAC address for a specific interface.
