How to set up IPv6 service on the TP-Link wireless router
IPv6 Link Local addresses are used by devices for communicating with other nodes on the same link. The scope of an IPv6 Link Local address is the local link. IPv6 Link Local addresses are auto-generated and many international technology leaders generate IPv6 Link Local addresses from MAC Address of the interface. When private (cluster only) networks with multiple NICs are detected, the cluster will automatically recognize IPv6 Link Local (fe80) IP addresses for each NIC on each subnet. This saves administrators time since they no longer have to manually configure IPv6 Link Local (fe80) IP Address resources. A device may only need a link-local address because it only needs to communicate with other devices on its same network. Or it can use its link-local address to communicate with a device where it can obtain information for getting or creating a global unicast address, such as an IPv6 router or a DHCPv6 server. Explanation: Link-local addresses refer only to a particular physical link and are used for addressing on a single link for purposes such as automatic address Link-local or global anycast addresses can be "baked in the code". Further study is required on the need for anycast addresses with scope between link- local and global. 4. Deprecation This document formally deprecates the IPv6 site-local unicast prefix defined in , i.e., 1111111011 binary or FEC0::/10. The special behavior of this prefix MUST Statically defined IPv6 link-local. Like most defaults, we can override them. For example, below I am assigning FE80::1 as the IPv6 link-local address for Router A and FE80::2 as the IPv6 link-local address for Router B. All devices using IPv6 will have at a minimum a link-local address. These are easy to spot, they start with an F. Like the name suggests, link local is only local to the link - the address will not be available from other networks. Link local addresses are generated automatically, and cannot be removed or disabled. Just let them be and ignore
IPv4 vs IPv6: What's The Difference, And Should You Care
Configuring an IPv6 link-local address The undo ipv6 address auto link-local command can only remove the link-local addresses generated through the ipv6 address auto link-local command. However, if an IPv6 global unicast address is already configured for an interface, the interface still has a link-local address because the system automatically generates one for the interface.

Local subnetwork Addresses in the range of 224.0.0.0 to 224.0.0.255 are individually assigned by IANA and designated for multicasting on the local subnetwork only. For example, the Routing Information Protocol (RIPv2) uses 224.0.0.9, Open Shortest Path First (OSPF) uses 224.0.0.5 and 224.0.0.6, and Multicast DNS uses 224.0.0.251.
Solved: EIGRP IPv6 Link-Local Only Routing - Cisco Community Re: EIGRP IPv6 Link-Local Only Routing But if you need to route to that specific subnet configured using the "ipv6 nd" command, you need to have the route in the routing table anyway. And as far as the the configuration is concerned, it is not that big of a deal to add the "ipv6 address" under the interface. What You Need to Know about IPv6 Link-Local Addresses An IPv6 multicast address for well-known link-local messages would start with “FF02” and you may recognize that FF02::1 is the all-nodes link-local multicast group address. Only IPv4 has broadcast as a method of sending one packet to ALL nodes on the current LAN. IPv6 Link Local Address Explained | Dotcom-Monitor Tools Blog
