IPv6 Neighbor Discovery Process
- Determines the link-local address of a neighbor-devices (all devices on the same link/LAN)
- Verifies the reachability of a neighbor
- Keeps track of neighboring devices
IPv6 Neighbor Solicitation Message
- Sent on the local link when a node wants to determine the link-layer address of another node on the same local link (see the figure below). When a node wants to determine the link-layer address of another node, the source address in a neighbor solicitation message is the IPv6 address of the node sending the neighbor solicitation message. The destination address in the neighbor solicitation message is the solicited-node multicast address that corresponds to the IPv6 address of the destination node. The neighbor solicitation message also includes the link-layer address of the source node.
IPv6 Link-layer addresses appear to be the same as Link-local addresses (are they TECHNICALLY the same?)
