ccnp实验手册-IPV6

1、IPV6中OSPFv3实验注意讲组播Ipv6地址长度128bit，每4bit转换成一个16进制，32个16进制，每四个16用“：”隔开。Ipv6的地址配置非常繁琐，所以ipv6同样支持自动的地址分配：1. 有状态：DHCPv6 2. 无状态：每个pc自己生成ipv6地址，每个pc自己生成的地址不会重叠，网络自动相同。1. 网络位64：每个pc会自动发送请求到网关，通过icmp-v6来实现，以此来同步网络位。2. 主机位64：直接用mac地址来替换主机位地址，为了把mac地址填充成64位，采用EUI64标准，就是在mac中间插入FFFE，原有mac地址第二位bit反转。Ipv6传输1. 单播2.

2、 组播3. 任意播 anycast：所有的服务器使用相同地址，可以访问时找到最近。FE80地址就是本地链路地址，使用此地址发送的数据只能在直连网段和链路上传输，相当ttl为1的意思；路由之间交互传递动态路由就是通过自身FE80地址发送，所以对端的下一跳自然也是本端的FE80地址。Ipv6支持的路由协议主要有：OSPF v3RIP ngR1(config)#ipv6 router rip df 建立rip进程，df为进程名R1(config-rtr)#exitR1(config)#int lo 0R1(config-if)#ipv6 rip df enable 启动接口，通告此接口路由R1(co
