Currently we make use of a "VLAN and network per customer" model and NAT. I'm considering building a single routed network and making use of PVLANs to keep customer data separately for the smaller customers.
I'm familiar with PVLAN basic implementation, terminology and meanings however what I don't understand, and can't find any good guides on, is how PVLANs work between switches. For example of the lacking documentation, have a look at Dell's and Cisco's implementation guides on PVLANs.
In my scenario connectivity goes as follows:
Firewall <> Cisco 2960 <> Dell 6348 <> Vmware DVswitch (Currently 4.1, soon 5.0) <> Host
I understand the Firewall would be on a Promiscuous port (Primary VLAN) on the Cisco 2960, and I understand the Hosts would be on an Isolated VLAN on the Vmware DVswitch. My question however is how to I configure the interlinks between these switches to preserve my PVLAN environment? Also as an aside, what happens to traffic in a PVLAN when it hits a non PVLAN aware switch?
Thanks in advance for any advice or pointers!
