Chapter 6. Link-Local Unicast Address
Link-local addresses (LLA) are unicast addresses that are confined to a single link. The term link refers to a network segment or subnet. Therefore, link-local addresses are local only to a particular link or subnet and not routable off the link. Link-local addresses need only be unique on that link because these packets are not routable off the link. This is true of both source and destination link-local addresses. In other words, routers should not forward any packets with link-local source or destination addresses.
Figure 6-1 illustrates link-local addresses as one type of unicast address.
