Briefly describe the following ICMPv6 message types: Neighbor Solicitation and Neighbor Advertisement.
What will be an ideal response?
Neighbor Solicitation (NS) (ICMPv6 type 135)-A node can send a Neighbor Solicitation message to find (or verify) the link-layer address for a local node, to see if that node is still available, or to check that its own address is not in use by another node, which is known as Duplicate Address Detection (DAD).
Neighbor Advertisement (NA) (ICMPv6 type 136)-When requested, or when its own link-layer address changes, a node sends a Neighbor Advertisement message that includes its IPv6 address and its link-layer address. This helps to establish physical adjacency (which is often more important than logical adjacency by address) to neighboring nodes.
