某企业全网使用了的设备,网络拓扑图如下。L3SW1 和 L3SW2 为内网核心设备, RSR 为出口器, L2SW 为接入交换机。内网双核心采用 MSTP+VRRP,正常情况下内网用户 VLAN10 的网 S5750E-A,VLAN20 的网 S5750E-B,当网络链路或内网核心设备出现问题时用户的网关自动切换到另外一条链路或设备上,实现内网的冗余和分流。内网双核心和出口器使用 OSPF 作为协议,保证全网可达。出口器使用静态 IP 连接运营商,配置地址转换实现内网用户访问互联网。内网有一台服务器,对外发布 http 服务。根据上述描述,请您回答下列问题。 为了让内网用户访问互联网,以下关于器的配置正确的是( )
