address of other nodes, find routers, and maintain reachability information.
The Neighbor Discovery protocol uses Neighbor Solicitation (ICMPv6 type 135)
to query target nodes for their link-layer addresses.

IPv6 routers may allow on-link IPv6 nodes to create and update the
router's neighbor cache and forwarding information.  A malicious IPv6 node
sharing a common router but on a different physical segment from another
node may be able to spoof Neighbor Discovery messages, allowing it to update
router information for the victim node.");
