ipv6 prefix-list

IPv6 Prefix List是一种IPv6路由过滤机制,它可以根据IPv6地址前缀来过滤路由。与IPv6 ACL不同,IPv6 Prefix List只有命名方式,没有数字形式,也只有扩展格式,没有标准格式。IPv6 Prefix List可以用于过滤路由,也可以用于路由策略。在配置IPv6 Prefix List时,可以使用deny或permit语句来拒绝或允许特定的IPv6地址前缀。同时,可以使用seq命令来指定每个语句的顺序。IPv6 Prefix List的应用需要与路由协议配合使用,例如在EIGRP协议中,可以使用distribute-list命令将IPv6 Prefix List应用到路由分发中。

.RT1串行链路、RT2串行链路、FW1、AC1之间分别运行RIP和RIPng协议,FW1、RT1、RT2的RIP和RIPng发布loopback2地址路由,AC1 RIP发布loopback2地址路由,AC1 RIPng采用route-map匹配prefix-list重发布loopback2地址路由。RT1配置offset值为3的路由策略,实现RT1-S1/0_RT2-S1/1为主链路,RT1-S1/1_RT2-S1/0为备份链路,ipv4的ACL名称为AclRIP,ipv6的ACL名称为AclRIPng。RT1的S1/0与RT2的S1/1之间采用chap双向认证,用户名为对端设备名称,密码为Key-1122。
以下是配置示例:

注意:以上配置仅供参考,实际配置需要根据网络拓扑和需求进行调整。
ipv6 nat v6v4 source list nat64 interface GigaEthernet0/3
抱歉,我之前的回答有误。在 IPv6 中,没有像 IPv4 中的 NAT(网络地址转换)功能,因为 IPv6 的地址空间足够大以满足全球需求。因此,`ipv6 nat v6v4 source list nat64 interface GigabitEthernet0/3` 这样的命令是不存在的。
IPv6 使用不同的机制来实现类似于 NAT 的功能,例如,IPv6使用网络前缀转换(Network Prefix Translation,NPT)来实现类似于 IPv4 NAT的转换功能。
