4.公司内部有两个网段,192.168.1.0/24和192.168.2.0/24,使用三层交换机SwitchB实现VLAN间路由。为提高用户体验,网络管理员决定带宽要求较高的192.168.1.0网段的的数据通过高速链路访问互联网,带宽要求较低的192.168.2.0网段的数据通过低速链路访问互联网。请根据描述,将以下配置代码补充完整。

【问题2】(2分)
在问题1的配置代码中,配置ACL 3000的作用是:(14)。
【问题3】(5分,每空1分)
公司需要访问Intermet公网,计划通过配置NAT实现私网地址到公网地址的转换,ISP1公网地址范围为202.100.1.1~202.100.1.5;ISP2公网地址范围为104.114.128.1~104.114.128.5。
请根据描述,将下面的配置代码补充完整。
