IPv4 neighbor function IPv6 neighbor function Description
ARP Request message Neighbor solicitation
message
A node sends this message to
determine the link-layer address of a
neighbor or to verify that a neighbor is
still reachable through a cached link-
layer address. You can also use
neighbor solicitations for duplicate
address detection.
ARP Reply message Neighbor advertisement A node sends this message either in
response to a received neighbor
solicitation message or to
communicate a link layer address
change.
ARP cache Neighbor cache The neighbor cache contains
information about neighbor types on
the network. See
Neighbor discovery
cache on page 25.
Gratuitous ARP Duplicate address
detection A host or node sends a request with its
own IP address to determine if another
router or host uses the address. The
source receives a reply from the
duplicate device. Both hosts and
routers use this function.
Router solicitation
message (optional) Router solicitation
(required) The host sends this message upon
detecting a change in a network
