IPv6 enabled devices automatically configure these addresses if other Unicast .Stiamo parlando dell’indirizzo link . The following example shows how to enable IPv6 processing on the interface and configure an address based on the general prefix called my-prefix and the directly specified bits: .hostname R3 ! ipv6 cef ! ipv6 unicast-routing ! interface Loopback10 no ip address ipv6 address FD01::/64 eui-64 ipv6 ospf 1 area 1! interface Loopback20 no ip address ipv6 address FD20::/64 eui-64 ipv6 ospf 1 area 2! interface Serial0/0 no ip address ipv6 address FE80::AB8 link-local ipv6 address 2002::2/124 ipv6 ospf 1 area 0 clock rate . The following code provides examples showing how to use the The .In diesem Artikel. Specifically, a node sends a neighbor solicitation message with an unspecified source address and a tentative link . We use different names for these but the idea is the same. Only the 64-bit network prefix for the address needs to be specified; the last 64 bits are .When IPv6 addresses are used in the context of a web address, they need to be encapsulated in square brackets: https://[dead:beef::]/ would be used in curl command or web browsers to contact dead:beef:: IPv6 address over HTTPS protocol.In IPv6, link-local addresses are always assigned, along with addresses of other scopes, and are required for the internal functioning of various protocol components. Unique local addresses can be routed, but only within one routing domain. Für IPv6-link-lokale Adressen (fe80::/10-Präfix) ist das .Die Link-Local-Adresse in IPv6 ist eine besondere Art von IP-Adresse, die nur innerhalb eines einzelnen Netzwerksegments (z.When using an IPv6 link-local address to connect to a host, a zone index must be added to the address so that the packets can be sent out on the correct interface. In generale, non vi è garanzia che un indirizzo link local sia univoco.Eine Link-Local-Adresse ist eine IPv6-Unicast-Adresse, die mit dem Link-Local-Präfix „FE80::/10 (1111 1110 10)“ und der Schnittstellen-ID im geänderten EUI-64-Format an jeder Schnittstelle automatisch konfiguriert werden kann. Beide Adressen gehören der Gruppe Unicast Adressen an und erstere sind mittlerweile auf fast allen Systemen zu finden. Ogni device e’ in grado di calcolare autonomamente un proprio indirizzo IPv6 per ogni interfaccia utilizzabile solamente all’interno di una rete broadcast (in soldoni una LAN), quindi non routato dai router IPv6. Und noch was: Windows fügt hinter der Adresse ein Prozentzeichen hinzu. Diese Adresslänge erlaubt eine unvorstellbare Menge von 2 128 oder 3,4 x 10 38 IPv6-Adressen.IPv6 link-local addresses are used to communicate with nodes (hosts and routers) on an attached link. 注意：在本链路上，路由表中看到的下一跳都是对端的Link Local地址,不是公网IP地址. The following image shows the structure of these addresses. Global Unicast. 其前缀64位为标准指定的，其后64位按EUI-64格式来构造.For IPv6 link-local addresses (fe80::/10 prefix), the sin6_scope_id member in the sockaddr_in6 structure is the interface number. If there is no answer after a predetermined number of .

In der Regel reicht der .2 Link-local addresses.IPv6 では IPv4 からの改良のため、ルーティングのネクストホップとして使われますが、その説明の前段として IPv4 での問題点を説明しておきます。. Link-Local-Adressen sind nicht unbedingt an die MAC-Adresse gebunden (konfiguriert im EUI-64-Format). Packets with these addresses are not forwarded by routers. It is valid in some circumstances to refer to a MAC address as a link-local address but it is a less common use of the term. These addresses are used to communicate between hosts on the same link. Ces adresses font uniquement référence à un lien physique particulier et sont utilisées pour les adresses sur un lien unique à des fins telles que la configuration automatique des .Firs, link-local address is alway an IP address.For MAC to IPv6, the 48-bit MAC address is split in half, 16 bits are inserted in the middle, those bits being ff:fe, then it is prepended by the 64-bit link-local prefix fe80::, and finally the 7th bit in the 5th IPv6 segment is flipped, to get the 128-bit IPv6 link-local address. 范围：只能在本地链路使用，不 . For this reason, ULAs are somewhat analogous to IPv4 private network addressing, but with significant differences.The link-local address can be used only to communicate with nodes on the same link.IPv6 Link Local Address is the address used between Point-to-Point interfaces and provide IPv6 Neigbor Discovery.

View the following output of show command show ipv6 interface gigabitEthernet 0/0, in a Cisco router. IPv6 looks different than IPv4 but there are some similarities.This interface ID is based on the interface’s hardware address.

IPv6 Addressing

IPv6 is enabled, link-local address is FE80::C800:EFF:FE74:8.Instead of getting an address via DHCP, a NIC will hop on the network with a link-local IPv6 address and with this will have to ability to do further configuration automatically (soliciting neighbors, router, et cetera). Esses endereços se referem apenas a um link físico específico e são usados para endereços em um único link para fins como a configuração de endereço automática e o protocolo de descoberta de vizinho. For example we have unicast addresses and we still have a “public” and “private” range. A Cisco IOS device by default uses the EUI-64 method to generate the link-local address. Packets sourced from or destined to a link-local address are not forwarded out of the layer two domain by routers. A Microsoft Windows device will generate the link-local . To sum up Interface ID Creation with EUI-64 Format, assume that we have a MAC address of 11-11-22-22-33-33.I tried to ping both ways (from machine to device and device from machine) but all I get is Destination unreachable: Address unreachable (Exact output is provided below). For example, two people with laptop computers supporting IEEE 802. This interface ID can be produced by EUI-64 format for IPv6 Link Local Address. A mac address is 48 bits, an IPv6 address is 128 bits. When they mean this the addresses are always IP addresses, either IPv4 or IPv6. Improve this answer.The “IPv6 Link-Local address” can be thought of as the equivalent to IPv4’s Automatic Private IP Address (APIPA), which is between 169. These multicast addresses vary by Thread network, because it is built on the unicast Mesh-Local prefix (see RFC 3306 for more details on unicast-prefix-based IPv6 multicast addresses).
