为了测试我刚刚设置的新防火墙，我正在尝试在我们的核心交换机上实施基于策略的路由。我希望来自某些 vlan 的流量被路由到新防火墙，而其他一切继续通过旧防火墙路由。我正在尝试使用本指南。除了尝试在接口配置模式下运行“ip policy route-map”命令外，该指南中的所有内容都工作正常。IOS 告诉我这样的命令不存在。“show ip interface vlan”命令表示策略路由已禁用。有任何想法吗？
“show ver”的输出：

您有一个“IPBASEK9”映像，但您需要“ENTERPRISESERVICES”才能使用基于策略的路由；您可能需要 ENTERPRISESERVICESK9，因为原始图像是加密图像（K9 后缀）。
