IPv6地址分为单播地址、任播地址(Anycast Address)、组播地址三种类型。和IPv4相比,取消了广播地址类型,以更丰富的组播地址代替,同时增加了任播地址类型。 IPv6单播地址 IPv6单播地址标识了一个接口,由于每个接口属于一个节点,因此每个节点的任何接口上的单播地址都可以标识这个节点。发往单播地址的报文,由此地址标识的...

任意播地址通常用于特定服务(如DNS根服务器),且**子网路由器任意播地址(Subnet-Router Anycast Address)**是RFC 4291定义的唯一标准任意播地址(格式为 ::/64)。 2、报文路由机制 当客户端发送数据包到任意播地址时,路由协议(如BGP)自动将请求导向拓扑位置最近或路由成本最低的节点(基于AS路径、延迟等指标)。
例如,用户通过ipv6 address命令配置IPv6地址为2001:db8:5::10,前缀长度为124,则该IPv6地址对应的网络前缀也为2001:db8:5::10,属于子网路由器任播地址类型,无法配置为全球单播地址。如果用户需要配置任播地址,请执行ipv6 address anycast命令 接口上最多可配置10个全球单播地址 在同一设备的不同接口上,不支持...
Example The following example enables IPv6 processing on the interface, assigns the prefix 2001:0DB8:1:1::/64 to the interface, and configures the IPv6 Anycast address 2001:0DB8:1:1:FFFF:FFFF:FFFF:FFFE: switchxxxxxx(config)# interface vlan 1 ...
An anycast address is used for one-to-one-of-many communication, with delivery to a single interface. IPv6 addresses always identify interfaces, not nodes. A node is identified by any unicast address that is assigned to one of its interfaces. Note RFC 3513 does not define a broadcast ...

You implement this capability by configuring anycast addresses to identify the set of routers that belongs to Internet service providers. For example, you can configure one anycast address per Internet service provider. You can use the anycast addresses as intermediate addresses in an IPv6 routing ...
