The IPv6 Neighbor Discover (ND) is a set of messages and processes used to manage the interactions between neighbor nodes. The Neighbor Discovery Protocol (NDP) performs functions for IPv6 similar to the way the Address Resolution Protocol (ARP) and ICMP Router Discovery and Router Redirect protocols do for IPv4. However, it provides many improvements over its IPv4 counterparts. Based on the ICMPv6, the IPv6 NDP provides a series of functions such as address resolution, verifying whether a neighbor is accessible, repeated address detection, route discovery/prefix discovery, automatic address configuration, and redirection. For a node, when an IPv6 address is configured, the node check whether the IPv6 address is available and does not conflict with other addresses. If the node is a host, the router notifies the host of a better next hop address for forwarding packets to the destination address; if the node is another router, the router advertises its address, address prefix, and other configuration parameters to guide the host on parameter configuration. During the IPv6 packet forwarding process, the node needs to determine the link layer address and accessibility of a neighbor node.

What is LLDP
The Link Layer Discovery Protocol (LLDP) is a standard Layer 2 topology discovery protocol defined in IEEE 802.1ab. LLDP collects local device information including the management IP address, device ID, and port ID, and advertises the information to neighbors. Neighbors save the received information in their management information bases (MIBs). The network management system (NMS) can then use data in MIBs to query link status. LLDP is also used for neighbor discovery and neighbor link status query.
