Juniper SRX 240路由配置

Question

我正在使用Juniper SRX 240作为聚合路由设备，它通过访问交换机端口将Desktop (工作站)环境连接到Cisco第2层交换机后面的多个服务器环境，这些交换机通过中继端口连接到Juniper SRX。因此

笔记本电脑<--访问端口--> Juniper SRX 240 <--主干端口--> Cisco Layer 2 <--主干端口--> Brocade交换机<--访问端口-->服务器

我已经为VLAN配置了必要的RVI，为VLAN配置了静态路由和安全策略以及主机-入站流量等等。我只可以从笔记本电脑到RVI，在Juniper CLI上可以平分笔记本电脑，也可以在Brocade交换机(通过Cisco交换机上的中继端口)上平服务器网关。

我的问题是，我不能从笔记本电脑切换到挂在织锦开关上的服务器。我不知道是什么导致了这一点，我是否需要为驻留在Brocade交换机上的不同VLAN提供另一种安全策略？

Answer 1

所以我看到了一些奇怪的事情：

• 您有一个静态路由(192.168.33.0/24)到同一直接连接子网(vlan.33)中的主机--删除它。
• 您还在区域安全区(ge-0/0/1-5)下配置了L2接口，删除这些良好的安全区域只需要L3接口。

如果您的服务器位于192.168.208.0/24范围内，而在Brocade的另一端，则需要确保Brocade具有指向膝上型计算机VLAN 192.168.32.0/24的静态路由，返回流量下一跳为192.168.33.1。
