R1(config)#ipv6 unicast-routing R1(config)#interface FastEthernet0/0 IPv6 Addresses with an Embedded IPv4 Address All devices on a network need some way to identify themselves as a specific host. Early networks simply used a naming format, and a server on the network kept a map of MAC addresses to host names. Tables quickly grew very large and with this grew issues such as consistency and accuracy (see Figure 2.5 below). IP addressing effectively resolved this issue. Upon receiving the RS message, routers advertise their presence using RA messages, which typically include prefix information for the local link as well as any additional configuration, such as suggested hop limits. The information contained within the RA is illustrated in Figure 3.13 below: An IPv6 address is 128 bits in length and this is broken down into eight sets of 16 bits each separated by a colon when written in full format. Every 4 hex bits can range from 0000 to FFFF,ciscokits ccna complete lab workbook full version, with F being the highest digit available in hex numbering: In order to interface with the upper and further subdivided into the Logical Li Media Access Control (MAC) Sublaye the Network Layer and the MAC Subla Access switches send and receive traffic from endpoints; Distribution switches are the intelligence of the network, providing redundancy, QoS, and filtering; and In the first step of creating the EUI-64 address, the value FFFE is inserted into the middle of the MAC address, thereby expanding the MAC address from 48 bits, which is 12 hexadecimal characters, to 64 bits, which is 16 hexadecimal characters. The conversion of the 48-bit MAC address into the 64-bit EUI address is illustrated in Figure 3.18 below: IPv6 Routing Table - 13 entries valid lifetime 2591967 preferred lifetime 604767 End Device - a PC Next-hop router determination The second method of IPv6 compressed address representation is applicable to each 16-bit field and allows leading zeros to be omitted from the IPv6 address. When using this method, if every bit in the 16-bit field is set to 0, then one zero must be used to represent this field. In this case, not all of the zero values can be omitted. Table 3.2 below shows IPv6 addresses in the preferred form and how they can be compressed using the second method of IPv6 compressed form representation.
