Hi, Need help on cisco router...

[lamsf]

Hi,
Need help on cisco router...
I hv 4 routers, as below:

- router1 and router2 are both connected to router3 (via switch)
- router3 is then connected to router4

I hv created the following tunnels:
1. tunnelA - from router1 to router3
2. tunnelB - from router2 to router3
3. tunnelC - from router3 to router4

traffic from router1 will go to router4 via tunnelA-tunnelC
traffic from router2 will go to router4 via tunnelB-tunnelC

I would like to configure VRF at router3. How do I configure it? Should there be one VRF table for both tunnelA & tunnelB to tunnelC, or there should be 2 VRF tables for tunnelA-tunnelC and tunnelB-tunnelC, or I can't do it that way at all?

Pls help.

Thanks.
