6.2. 48-bit MAC algorithm to convert 64-bit To create EUI-64 addresses from vendor MAC addresses, perform the following steps: 1. Insert ff-ee between the third and fourth bytes of the MAC address. 2. Complement the "Universal / Local" (U / L) bit. (The U / L bit is the 'u' bit in IEEE EUI-64 terminology. Complementing this bit means to invert the bit from the original value and set it to either a 0 or 1. Setting the bit to 0 means that the interface identifier is locally administered; setting it to 1 indicates a globally unique interface identifier.) 6.3. Ipv6.exe rough solution http://www.6test.edu.cn/ In WindowsXP, the like of all the work on the configuration of IPv6 through ipv6.exe to complete. Open cmd window, and the implementation of ipv6, you can see some help to intercept are as follows: usage: ipv6 [-v] if [ifindex] ipv6 [-p] ifcr v *** v4src v4dst [nd] [pmld] ipv6 [-p] ifcr 6over4 v4src ...... This article is to introduce the ipv6.exe use. 1. Ipv6 install / uninstall WindowsXP, IPv6 protocol stack is the need to manually install, the installation method is the implementation of "ipv6 install". Of course, when IPv6 if you do not want to play, you can run "ipv6 uninstall" the IPv6 protocol stack dismantled. Note that sometimes a removable IPv6 protocol stack is necessary, because the WindowsXP brought to IE6 is to support IPv6, and If your machine installed on the IPv6 protocol stack, then when using IE to access some both IPv4 to IPv6 addresses and The site when the site, IE will first connect via IPv6, only if it fails to connect via IPv4, which IPV6 basic theory and tunnel access to P. 57 Connecting The IP World Kind of delay on the big, sometimes feel very bad mood.
2. Ipv6 if [ifindex] The ipv6.exe, all interfaces are identified through the interface index, the implementation of the "ipv6 if" will be able to see the All the interfaces to support IPv6 and its related information (including interface index). If you need to look at a specific interface, For example interface 4, then the implementation of the "ipv6 if 4" on it. 3. Ipv6 adu ifindex / address [life validlifetime] Through this command to an interface, you can add the IPv6 address, for example, if the interface 4 to add IPv6 to give Address 3ffe: 321f:: 1 / 64, you need to execute the following command: ipv6 adu 4/3ffe: 321f:: 1 Some people may ask why you do not specify a subnet mask is no way ah, ipv6 adu this command is You can not specify the subnet mask ah. So, you must specify a route, indicating what kind of interface are four sub-networks: ipv6 rtu 3ffe: 321f:: / 64 4 This is actually very normal, in the old versions of Linux, you specify the IPv4 in addition to a network card to Sites, need to use the "route" command to manually add a route to illustrate the piece of card is hanging on what kind of a sub-network On. Remove an IPv6 address method is too complicated, and I look for a long time finally understood how get - is the The address of a lifetime set to 0! For example, to delete the IPv6 address specified above, you can perform the following life Order: ipv6 adu 4/3ffe: 321f:: 1 life 0 4. Ipvt6 rt This command is used to look at IPv6 routing table, there is nothing a lot to say. 5. Ipv6 rtu prefix ifindex [/ address] [life validlifetime] This command is used to process IPv6 routing table. Note that the prefix is used to "address / prefixlen" form. For example, if you want to add the default route, gateway 3ffe: 321f:: 1111, You need to execute the following command: ipv6 rtu:: / 0 4/3ffe: 321f:: 1111
The deletion of the routing table entry deleted and interface addresses the same way as, the lifetime can be set to 0. For example, To remove the default route specified above, you can perform the following command: ipv6 rtu:: / 0 4/3ffe: 321f:: 1111 life 0 IPV6 basic theory and tunnel access to Page 58 Connecting The IP World Please note that I have written in the command line, "[/ address]" that the address can be omitted. In the following circumstances Next, the interface behind the address of the index can be omitted: (a) of this route that is that this interface where the local area network (for example, as shown in the previous section ipv6 adu) (b) the interface is a point-to-link interface (eg, IPv6/IPv4 tunnels, will explain later) 6. Ipv6 ifcr v *** v4src v4dst This command is used to create IPv6/IPv4 tunnel (tunnel). For example, you want to build with another machine IPv6/IPv4 tunnel, your IPv4 address is 166.111.8.28, the other side of the IPv4 address is 202.38.99.9, Then you can execute the following command: ipv6 ifcr v *** 166.111.8.28 202.38.99.9 Implementation of the End of this command, the system will tell you that the newly created index of the value of the interface. Right side of this interface, the configuration Law and other interface exactly the same, only need to note that it is a point-to-link interface. 7. Ipv6 ifd ifindex This command is used to delete an interface. For example, you have built an IPv6/IPv4 tunnel, its interface index To 5, and back you do not want this tunnel, and then you can execute the following command will delete it: ipv6 ifd 5 IPV6 basic theory and tunnel access to Page 59, Connecting The IP World About Allied Telesyn (Allied Telesyn) Allied Telesyn (Allied Telesyn) as the world's leading networking products and solutions provider, with over 200 all over the world Number of companies and branches.
