Configuration 1: Single Subnet with Link-local Addresses
Apr 28, 2011 · Issuing the no form of the ipv6 address command will replace a manually configured link-local address with an automatically configured one. Note that, due to the nature of link-local addresses, the fe80::/10 prefix does not appear in the routing table; it is considered available via all IPv6 interfaces. The link-local address of a node is the combination of the prefix fe80::/64 and the 64-bit interface identifier expressed in IPv6 colon-hexadecimal notation. Therefore, the link-local address of this example node with the prefix fe80::/64 and the interface identifier 02-60-08-ff-fe-52-f9-d8 is fe80::260:8ff:fe52:f9d8. Aug 09, 2017 · One method to make things easier is to manually assign the link-local address to the upstream router’s interfaces. If you assign the link-local address FE80::1 on each of its interfaces and if that link-local address is unique on each of those LAN segments, then this becomes the default gateway for the hosts on those LANs. El propósito de este documento es proporcionar una mejor comprensión de la dirección local de link IPv6 en una red. Una dirección local de link es una dirección unicast IPv6 que se puede configurar automáticamente en cualquier interfaz mediante el prefijo local de link FE80::/10 (1111 1110 10) y el identificador de interfaz en formato EUI-64 modificado. Oct 25, 2018 · So now, what to do about any other interfaces on the DHCP server machine? If those interfaces have only link-local addresses (i.e. belonging to fe80::/10 prefix), the server will complain about not being able to detect to which subnet they are connected. You can do one of 3 things here: Disable the interface (ifconfig eth0 down). Aug 07, 2013 · In IPv6 Link-Local addresses are mandatory addresses according to RFC 4291. This means that all interfaces are required to have at least one Link-Local unicast address from the address block fe80::/10, which has been reserved for link-local unicast addressing. The actual link-local addresses are though assigned with the prefix fe80::/64.
ipv6 - Why is fe80::/10 reserved for link local addresses
IPv6 Link-Local Addressing - J-Net Community But, section 2.5.6 restricts Link-Local address as FE80::/64 which would mean addresses from FE80:: through FE80::FFFF:FFFF:FFFF:FFFF . Not true. RFC 4291 section 2.5.6 only says is that the first 10 bits are FE80 and subsequent 54 bits are 0. It does not say what the mask is and You are not restricted to using /64 netmask for link local windows - My dns server default to link-local IPv6 address

The actual link-local addresses are though assigned with the prefix fe80::/64. The Link-Local is however a fully functional address which you can use for multiple things. Using Link-Local. Here at the office my colleague has a desktop and his Link-Local Address is fe80::821f:2ff:fed6:5f08. So can I ping the address? wido@wido-desktop:~$ ping6 fe80::821f:2ff:fed6:5f08 connect: Invalid argument wido@wido-desktop:~$
