【正文】 tly discarded the current agreement to use IPv4 INTERNET, use IPv6 prehensive agreement. Therefore, the IPv6 network construction must be considered with the current IPv4 protocol patible, there must be a transition from IPv4 to IPv6. This transition will be the key to the development of IPv6. China included IP expert, scholars are constantly practice and research, to solve various problems. Although, IPv6 implementations also exist many difficulties, but the powerful function of IPv6 and people on the Internet is the constant demand, will promote the IPv6 replace IPv4.Nowadays more and more people think, future telemunication network is the network based on IP technology. People trying to free IP network into an orderly, management, QoS security, to provide various valueadded business network. IPv6 as the future of the internet protocol, will bee the core technology of next generation network, will have tremendous development foreground.附 錄 II：譯文淺談ipv6近年來互聯(lián)網(wǎng)中出現(xiàn)了“IPv6”這個新名詞，我在借鑒許多專家學(xué)者的基礎(chǔ)上，簡單表述一下我對“IPv6”的認(rèn)識和理解。最后，再一次對所有給予我關(guān)心和幫助的老師、同學(xué)們表示誠摯的謝意，祝愿大家工作順利，健康快樂！參 考 文 獻(xiàn)[1] [美]Cprian Popoviciu． 部署IPv6網(wǎng)絡(luò)[M]． 北京：人民郵電出版社，2006.[2] 高陽 王建強(qiáng) [M]. 北京：清華大學(xué)出版社，2009.[3] 雷震甲 編著. 網(wǎng)絡(luò)工程師教程第三版[M]. 北京：清華大學(xué)出版社，2010.[4] 楊軼 蘇嘯鳴 吳越 編著. 深入解析IPv6第二版[M] ．北京：人民郵電大學(xué)出版社，2005.[5] 謝希仁 （第5版）[M]. 北京：電子工業(yè)出版社，2008.[6]（加）Regis Desmeules.

IPv6 is called the next generation Internet protocol, IPv6 is an acronym for Internet Protocol version sixth ( Internet Protocol Version 6 ). With the wide application of internet protocol pared with IPv4, IPv6 can provide abundant address resources, will be able to fully satisfy the future digital life needs, and IPv6 will provide more secure, more broad application and service.The address will be depleted, distribution is very unevenThis is our current work is facing the problem. The IPv4 protocol in IP address length of 32 bits, the theory about 4300000000 ( 232) address, but uses A, B, C addressing mode, the available number of addresses to sell at a discount greatly, in the increasingly expansion before the network, IP address has been scarce. Forecast according to the expert, in the next two years IP address will be allocated. Although the NAT and CIDR methods, but those in the original space of potential approaches still can not change the address to be exhausted to the reality。再次我要感謝我的指導(dǎo)老師劉君玲老師，是她給了我這個畢業(yè)設(shè)計課題，同時在我的整個畢業(yè)設(shè)計過程中，劉老師給我提出了許多具有指導(dǎo)性的建議，并給予了我耐心的指導(dǎo)和督促，使我能順利完成畢業(yè)設(shè)計。在這里我實現(xiàn)了自己的理想，在以后的路上我將帶著您們教給我的一切去繼續(xù)努力奮斗。他們在我的學(xué)習(xí)和生活中，給了我最大的關(guān)懷和幫助，在四年的大學(xué)學(xué)習(xí)中是在你們的指導(dǎo)下，我才打下了扎實的基礎(chǔ)知識，成為一個合格的本科畢業(yè)生。我想這是我生命中一段美好、難忘的時光，是我不斷超越自我的歷程。Ipv6作為下一代互聯(lián)網(wǎng)的核心協(xié)議，將會涉及到多種層面，會需要更多不同部門和服務(wù)商的參與，共同推動ipv6 技術(shù)向著一個嶄新的網(wǎng)路時代發(fā)展。雖然Ipv6內(nèi)置了對IPSec（一種互聯(lián)網(wǎng)安全標(biāo)準(zhǔn)，可在兩個端點之間進(jìn)行授權(quán)和加密通信）的支持，長期來看，IPv6是會極大地提升互聯(lián)網(wǎng)的安全性，因為每個端點都能夠加密。總體來說IPv6與IPV4相比具有以下幾個優(yōu)勢：(1)IPv6具有更大的地址空間；(2)IPv6使用更小的路由表；(3)IPv6加入了對自動配置(Auto Configuration)的支持；(4)IPv6具有更高的安全性。IPv6和IPv4部分能夠很好的兼容工作。 R2(config)ipv6 route 2001:1:2:1::0/64 2001:1:2:2::1（5）步驟5：查看RR2路由表信息： 使用命令：show ipv6 route圖424 R1的路由表信息圖425 R2的路由表信息（6）步驟6：在客戶機(jī)PC3上 ping DNS、WEB服務(wù)器地址通，訪問WEB。第4章 詳細(xì)設(shè)計與實現(xiàn)過程 IPV6的RIP實現(xiàn) 拓?fù)浣Y(jié)構(gòu)圖圖41 拓?fù)浣Y(jié)構(gòu) IPv6地址規(guī)劃表41 IPv6地址規(guī)劃Pc12001:1:1::2/64Rb f0/12001:1:2::2/64R1 f0/0 2001:1:1::1/64Rb f0/02001:1:3::1/64R1 f0/12001:1:2::1/64Pc22001:1:3::2/64 配置過程（1）步驟1：配置PC機(jī)的ipv6地址及默認(rèn)網(wǎng)關(guān)圖42 配置ipv6地址圖43 配置默認(rèn)網(wǎng)關(guān) （2）步驟2：配置路由器Ra R1 (config)ipv6 unicastrouting //啟用IPV6單播服務(wù) R1 (config)ipv6 router rip 1 //啟動IPv6 RIPng 進(jìn)程 R1 (config)interface f0/0 R1 (configif)ipv6 address 2001:1:1::2/64 R1 (configif)ipv6 rip 1 enable //在接口上啟用RIPngR1 (configif)no shutdownR1 (config)interface f0/1R1 (configif)ipv6 address 2001:1:2::1/64 R1 (configif)ipv6 rip 1 enableR1 (configif)no shutdown（3）步驟3：配置路由器RbR2 (config)ipv6 unicastroutingR2 (config)ipv6 router rip 1R2 (config)interface f0/0R2 (configif)ipv6 address 2001:1:3::1/64R2 (configif)ipv6 rip 1 enableR2 (configif)no shutdownR2 (config)interface f0/1R2 (configif)ipv6 address 2001:1:2::2/64R2 (configif)ipv6 rip 1 enableR2 (configif)no shutdown（4）步驟4：測試及抓包過程圖44路由器使用icmp協(xié)議請求邏輯地址和物理地址 圖45路由器使用rip協(xié)議通信（5）步驟5：查看路由表 圖46 RA路由表圖47 R B路由表 Ipv6的Ospfv3實現(xiàn) 拓?fù)浣Y(jié)構(gòu)圖圖48 拓?fù)浣Y(jié)構(gòu)圖 IPv6地址規(guī)劃 表42 IPv6地址規(guī)劃Pc12012:1:1::2/64R2 f0/02012:1:3::1/64R1 f0/02012:1:1::2/64R3 f0/02012:1:3::2/64R1 f0/12012:1:2::1/64R3 f0/12012:1:4::2/64R2 f0/12012:1:2::2/64Pc22012:1:4::1/64 配置過程（1）步驟1：配置PC機(jī)的ipv6地址及默認(rèn)網(wǎng)關(guān)圖49配置pc的ipv6地址圖410配置pc的默認(rèn)網(wǎng)關(guān)（2）步驟2：配置路由器R1R1(config)ipv6 unicastroutingR1(config)ipv6 router ospf 1 //啟動OSPFv3 路由進(jìn)程R1(configrtr)routerid //定義路由器IDR1(config)interface f0/0R1(c
