[c-nsp] Question about VRF

Hello,

Can anyone advise on this situation?

Topology:
Picture a Firewall at the Top of the network, this has 3 interfaces on it.
each interface goes to a router (logical) so 2 VRF's and one native routing
domain.
So theres 3 logical routers, each router has a VLAN on it which is trunked
to a switch, that is divided into those 3 vlans...(3 logical switches)

If you draw this out it's all separate right. Is this a valid setup? It
seems if you dont physically separate each VRF'ed VLAN you get stuck.

The switch tries to send the traffic to its native router and not the VRF'ed
Vlans, or its default gateway. Theres no way to specify i want traffic to be
sent to a different gateway. Although it should send the traffic within its
VLAN.

I need to be able to logically divide my router, then have vlans within each
"router" which are trunked to a switch, which then use each different path
to get out.

Please advise.

Thank you,
