ospfv3 双栈 1
实验目的：使用ospfv3 传递ipv4/ipv6 路由，观察路由表，db，报文
拓扑如下：
地址规划： R1 lo0 1.1.1.1/32，2000::1/64 ，r1-r2互联地址2012::1/64 ，其他地址类似
R6 引入lo1 66.6.6.6/32 和2066::6/64 模拟外部路由
1 ： 启用ipv6 单播路由，配置ospfv3 1 ，router-id ，以R1为例，其他类似
ipv6 unicast-routing router ospfv3 1 router-id 1.1.1.1
2 ： 配置地址, 接口宣告ospfv3 。 以R1: lo 0 为例， 其他类似
interface Loopback0 ip address 1.1.1.1 255.255.255.255 ipv6 address 2000::1/64 ipv6 enable ospfv3 1 ipv6 area 1 ospfv3 1 ipv4 area 1
3 ： 修改R1 R2 互联网络类型 p2p
int e/1
ospfv3 1 network point-to-point
4 : 检查 邻居： 可以看出， ospfv3 使用 ipv4 /ipv6 地址族分别建立了邻居

5 R6 重分布 lo1
定义两条前缀列表：
ip prefix-list con-6 seq 5 permit 66.6.6.6/32
ipv6 prefix-list con-6 seq 5 permit 2066::/64
定义route-map
route-map Con permit 10
match ipv6 address prefix-list con-6
route-map con permit 10
match ip address prefix-list con-6
重分布 lo1

r1#sh ip route ospf // ospfv2 啥也没有
r1#sh ipv6 rou ospf
