VLANS on 6500

I have a CAT-6500 with a 6348.


Ports 1-6 on VLAN100

Ports 7-12 on VLAN200

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

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

The problem I'm having is that on these 2 VLANS I also have to run a "sub-network" in the 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

VLAN100.2 with an ip of

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

VLAN200.1 with an ip of

VLAN200.2 with an ip of

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

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

ip address secondary

and then configure a routing Protocol to route between these Vlans
