Cisco 3660 and two 3500XL

I have a 3660 configured with two FastEthernet interfaces and one Ethernet.

The Ethernet is directly connected to the Internet.

FastEthernet0/0 is connected to a server network, actually it is split into several VLANs. Physically the FastEthernet0/0 is connected to a 3512XL which connects all the servers together.

The other FastEthernet interface, 1/0, is connected to a 3548 where the clients are connected. This interface is split into several VLANs as well, one for "normal" users, one for Wireless Clients and so forth.

Now, we're doing a testing with VoIP clients. Of course, the clients will be connected to the 3548 switch and into FastEthernet1/0.x

The H.323 Gatekeeper on the other hand is housed in the server rack and so is connected to the 3512 switch. Now, I want the server and clients to be on the same subnet.

Is this possible?

I thought of creating say subinterface for the VoIP network for the clients and then another for the server and doing a ip unnumbered on that one.

example config:

! Interface connected to 3512

interface FastEthernet0/0.5

encapsulation dot1q 5

ip address 192.168.50.1 255.255.255.0

cdp enable

interface FastEthernet1/0.5

encapsulation dot1q 5

ip unnumbered FastEthernet0/0.5

is the above possible?

I understand that one way would be to connect the two switches directly, but I do not wish to do that (long distance among other things)...

thanks

Re: Cisco 3660 and two 3500XL

I strongly believe that this configuration won't work according to your requirement. Because, in routers the configuration for Inter-VLAN routing is applicable to that configured interface only.
