VLANS on 6500

I have a CAT-6500 with a 6348.

Scenario:

Ports 1-6 on VLAN100

Ports 7-12 on VLAN200

In MLS Card the virtual interface for VLAN100 I have a network in the 215.128.3.0

In MLS Card the virtual interface for VLAN200 I have a network 215.128.4.0

The problem I'm having is that on these 2 VLANS I also have to run a "sub-network" in the 10.0.0.1 block for management purposes.

So what I'm thinking is that on the MLS card on the virtual interface for VLAN100, I assigned it no IP Address and created 2 sub-interfaces

VLAN100.1 with an ip of 215.128.3.1

VLAN100.2 with an ip of 10.0.1.1

On the virtual interface for VLAN200, I assigned it no IP address and created 2 sub-interfaces

VLAN200.1 with an ip of 215.128.4.1

VLAN200.2 with an ip of 10.0.2.1

But I can't get the VLAN100.1 to talk to VLAN200.1 to talk to eachother.

What am I doing wrong, or am I going about this the wrong way.

Re: VLANS on 6500

i have never worked with Sub-Interfaces on Vlans, so i would use one Interface like that:

interface Vlan100

ip address 215.128.3.1 255.255.255.0

ip address 10.0.0.1 255.255.255.0 secondary

and then configure a routing Protocol to route between these Vlans
