IPv6原理概IPv6InternetProtocolVersion6InternetProtocol譯為“互聯網協議”IPv6IETF（互聯網工程任務組，InternetEngineeringTaskForce）IP協議（IPv4）的下一代IPIP4（IPv4，它的下一個版本就是IPv6IPv4相比，IPv6具有以下特點IPV6128296IPIPV4中可變長度的選項字段。IPV6中選項部分的出現方式也有所變化，使路由器可以簡單路過選InternetIPv4用戶和設備，IPv4v6的過渡不可能實現。而且，許多企業和用戶的日常工作越來越依賴于Internet，它們無法在協IPv4v6IPv6帶來的好處的同時仍能與網絡中其余的IPv4用戶通信。能否順利地實現從IPv4到IPv6的過渡也是IPv6能否取得成功的一個重要因素。IPV4IPV6IETF組織專門實驗目IPv6掌握配置IPv6掌握配置IPv6ISIS掌握配置IPv6實驗內OSPFv30Router10.1.1.110.2.2.210.3.3.3；R4，R5R6ISISIPv6ID49.0001，并且都是Level-2R2R4間的網絡是一個純IPv4OSPFv2IDR6，R7IPv4ISISIPv4IDR1，R2R3IBGP4+IPv6鄰居關系，AS100R2通告默認路由；R4R5IBGP4IPv6鄰居關系，ASR2和R4之間通過直連IPv6地址建立EBGPIPv6鄰居關系；要求R2
