I am working with a Juniper SRX 240 as an aggregation routing device, it connects a Desktop (Workstation) environment over an access switch port to several (4) server environments behind Cisco Layer 2 switches which are connected via trunk ports to the Juniper SRX. Hence
Laptop <-- access port --> Juniper SRX 240 <-- trunk port --> Cisco Layer 2 <-- trunk port --> Brocade Switch <-- access port --> Servers
I have configured the necessary RVIs for the VLANs, static routes for the VLANs and security policies and host-inbound-traffic etc. I can ping from the laptop to the RVIs only, on the Juniper CLI I can ping the laptop and can also ping the server gateways on the Brocade switch (Via the Trunk port over the Cisco switch).
My problem is this, I cannot ping from the laptop to the Servers hanging off the brocade switch. I am unsure what is causing this, do I need another security policy for the different VLANs residing on the Brocade switch?
