ccna 200 301 complete course.If the host uses the EUI-64 option, the address constructed by the host is predictable. The prefix portion of the address is the prefix defined by the local IPv6 router. The host's MAC address is then added to some EUI-64 rules to change the 48-bit MAC address to a 64-bit interface ID, as follows.(1) Divide the 6-byte (12 hex digits) MAC address into two halves (each with 6 hex digits). [. (2) Insert FFFE between the two halves, so that the interface ID now has 16 hex digits (64 bits).(3) Convert the seventh bit of the first byte.Figure 16-8 shows the main components of forming an address. Figure 16-8 IPv6 Address Format Using Interface ID and EUI-64Calculated by the router as informed by the NDPRouter Addresses and Static Route Configuration So far, you have reviewed IPv6 addresses, IPv6 subnetting, and how to assign addresses to hosts. The next section will cover how to assign addresses to routers, enable IPv6 routing, and configure static IPv6 routes. Converting Bit 7 of Byte 1Configuring IPv6 Routing and Addresses on a Router (read from left to right) In order to enable IPv6 on a router, two basic tasks need to be completed.12.2 Basics 335Turtle iH Step 1 Use the ipv6 unicast-routing global command to start IPv6 routing. Step 2 In interface configuration mode, use the ipv6address address/length subcommand to start IPv6 on each desired interface,set the IPv6 address and prefix length of the interface.In many cases within the enterprise, IPv6 implementation plans use a dual stack strategy, at least on the router and, if possible, on the host. That is, the router still sends IPv4 packets and still has an IPv4 address on its interface. The configuration adds IPv6 routing as a second Layer 3W that can be routed by this router, thus becoming "dual stack".
