SW3模拟办事处产品和营销接口配置为loopback，模拟接口up。SW3模拟办事处与FW2之间运行OSPFv2协议，进程2，区域2，SW3模拟办事处发布loopback2、产品和营销。SW3模拟办事处配置ipv6默认路由；FW2分别配置到SW3模拟办事处loopback2、产品和营销的ipv6明细静态路由，FW2重发布静态路由到OSPFv3协议

RT1、FW2之间OSPFv2和OSPFv3协议，进程2，区域2；RT1发布loopback4路由，向该区域通告type1默认路由；FW2发布loopback1路由，FW2禁止学习到集团和分公司的所有路由。RT1用prefix-list匹配FW2 loopback1路由、SW3模拟办事处loopback2和产品路由、RT1与FW2直连ipv4路由，将这些路由重发布到区域0。

修改ospf cost为100，实现SW1分别与RT2、FW2之间ipv4和ipv6互访流量优先通过SW1_SW2_RT1链路转发，SW2访问Internet ipv4和ipv6流量优先通过SW2_SW1_FW1链路转发。
