Detailed explanation-1: -Typically, link-local IPv6 addresses have “FE80” as the hexadecimal representation of the first 10 bits of the 128-bit IPv6 address, then the least-significant 64-bits of the address are the Interface Identifier (IID).
Detailed explanation-2: -An IPv6 link-local address consists of the link-local prefix FE80::/10 (the 10 most significant bits are 1111111010) and an interface ID in the IEEE EUI-64 format (an EUI-64 interface ID can be created from an extended EUI-48 bit MAC address).
Detailed explanation-3: -Enter global configuration mode. device# configure terminal. Enter interface configuration mode. device(config)# interface ethernet 3/1. Configure a link-local IPv6 address for the interface. device(config-if-e1000-3/1)# ipv6 address FE80::240:D0FF:FE48:4672 link-local.
