cisco ccna zertifizierung.When using a multicast address, packets are typically delivered to all interfaces identified by that identifier.IPv6 does not have the concept of a broadcast address as previously mentioned for IPv4. To send packets in a broadcast fashion, theIPv6 hosts are to use multicast addresses. Several types of IPv6 addresses are also defined within the three main types of IPv6 addresses mentioned above. This book will not cover all types of IPv6 addresses, but will focus on two special types of IPv6 unicast addresses: public network unicast addresses and local link unicast addresses (LLAs)./iiH Simply put, the difference between a public unicast address and a local link unicast address is that the former can be used on the Internet1.7 IPv6 Basics 86routed over the Internet, whereas the latter's scope is limited to local links, which IPv6 hosts use to perform special functions, such as,performing neighbor discovery. The concept that an IPv6 host can have multiple IPv6 addresses on a single interface is unique to IPv6. For example, the same interface can have both an IPv6 local link address and a public unicast address. In fact, this is a common situation. According to the IPv6 specification, all interfaces of an IPv6 host should have at least one local link address.An IPv6 public unicast address is similar to an IPv4 public address. An IPv6 public unicast address consists of 3 parts, as Figure 1-70Assigned by the IP address assignment authority Assigned by the network administratorshown./with fit
