vrf-lite across multiple 6500 and 4500 switches?

Hi.

We have multiple edge 4500 switches terminating into two 6500 switches configured as VSS.

We are planning to set up dedicated test network on all switches.

This test network has to be only able to talk to each other.

Currently, 4500 to 6500 is configured as layer 3 connection.

my question is if I were to put Gi1/1-10 interfaces on 4500 as part of vrf test on each of the edge switches,

how do I have to configure the layer 3 link between 4500 and 6500?

is the only solution to get the vrf-lite working is to turn that link into 802.1q trunk?

or do I have to create something like vrf over GRE?

anyone has any idea or link, I would appreciate it.

Thank you

You can create subinterfaces on the inter-switch link and assign VRF TEST to the intended subnets while leaving other subnets/subinterfaces in the global routing table.
