Overview IPv6

IPv6 (Internet Protocol Version 6) is the second generation standard protocol of the network layer protocol, also known as IPng (IP Next Generation). It is a set of specifications designed by IETF (Internet Engineering Task Force) and an upgraded version of IPv4.

L3 interface ND proxy

L3 interface ND proxy is used to realize interworking of different network segments connected through two interfaces. Generally, the device will not respond to the NS request whose target is not the network segment corresponding to the packet receiving interface, so different network segments cannot directly communicate with each other. When the ND proxy function is enabled on the L3 interface, if the device receives NS belonging to other interface network segments from the interface, it can also respond to NA. Thus, the hosts belonging to different network segments can also establish neighbor entries and communicate normally. Its typical application scenario is the networking of large and small network segments.
