ccnp實驗手冊-IPV6

1、IPV6中OSPFv3實驗注意講組播Ipv6地址長度128bit，每4bit轉(zhuǎn)換成一個16進制，32個16進制，每四個16用“：”隔開。Ipv6的地址配置非常繁瑣，所以ipv6同樣支持自動的地址分配：1. 有狀態(tài)：DHCPv6 2. 無狀態(tài)：每個pc自己生成ipv6地址，每個pc自己生成的地址不會重疊，網(wǎng)絡(luò)自動相同。1. 網(wǎng)絡(luò)位64：每個pc會自動發(fā)送請求到網(wǎng)關(guān)，通過icmp-v6來實現(xiàn)，以此來同步網(wǎng)絡(luò)位。2. 主機位64：直接用mac地址來替換主機位地址，為了把mac地址填充成64位，采用EUI64標準，就是在mac中間插入FFFE，原有mac地址第二位bit反轉(zhuǎn)。Ipv6傳輸1. 單播2.

2、 組播3. 任意播 anycast：所有的服務(wù)器使用相同地址，可以訪問時找到最近。FE80地址就是本地鏈路地址，使用此地址發(fā)送的數(shù)據(jù)只能在直連網(wǎng)段和鏈路上傳輸，相當ttl為1的意思；路由之間交互傳遞動態(tài)路由就是通過自身FE80地址發(fā)送，所以對端的下一跳自然也是本端的FE80地址。Ipv6支持的路由協(xié)議主要有：OSPF v3RIP ngR1(config)#ipv6 router rip df 建立rip進程，df為進程名R1(config-rtr)#exitR1(config)#int lo 0R1(config-if)#ipv6 rip df enable 啟動接口，通告此接口路由R1(co
