An anycast address is very different from an IPv4 broadcast address in that it can be assigned to many interfaces, but indicates the nearest interface. An IPv6 multicast address is similar to an IPv4 multicast and also indicates multiple interfaces. A unicast address indicates a single interface. The global unicast address is 2000::/3; the loopback address is ::: 1; the site-local private address is FEC::.FFF::; and the link-local address is FE8::. FEB::.IPv6 discards the fields in the IPv4 header and no longer uses them. IPv6 headers are simpler, which improves the efficiency of today's networks o IPv6 also discards protocols such as ARP and IGMP, whose functions are assumed by ICMPv6. ICMPv6 also adds a number of new features, including routers, DNS servers, and neighbor discovery.The most common way to assign static addresses to interfaces is to use the EUI-64 method. DHCPv6 and stateless autoconfiguration allow devices to dynamically acquire addresses, and in stateless autoconfiguration this is achieved by dynamically requesting subnet IDs from routers and generating interface IDs using EUI-64.Routing protocols supported by IPv6 include static, RIPng, 0SPFv3, IS-ISforIPv6.MP-BGP4, and EIGRPforIPv6o RIPng uses UDP port 521 in its connections, and its destination address is the multicast address FF02::9o When migrating from IPv4 to IPv6, the most common transition methods include dual-stack and 6to4 tunneling techniques. In dual-stack, the device runs two protocol stacks simultaneously; in 6to4 tunneling, IPv6 packets are encapsulated in IPv4 packets for transmission over the IPv4 backbone to another IPv6 network.The command ipv6 unicast-routing must first be executed to enable IPv6o for the interface to handle IPv6 packets, it must be assigned an IPv6 address, which is typically assigned using the EUI-64 method. You must first configure RIPng globally, then enable it on the interface and use a tag to specify the RIPng routing process to which the interface belongs. Like RIPng, OSPFv3 and EIGRP must also be configured globally before being enabled on the interface. In the OSPFv3 global configuration, specify the router ID and area number; then, associate the interface to the area and OSPF process. In the EIGRPfor IPv6 global configuration, the autonomous system number must be specified, and the routing process may also be enabled using no shutdown.
