Does VRF depends on MPLS or they are separate entity?
Here is the senario, my client is co-lo with us at our spoke site, our spoke router is a 2620XM router and has a T1 link connect to our hub. To separate our my client's traffic, I run VRF on 2620XM. So my question is, do I need to enable MPLS on 2620XM in order to have VRF work? How does VRF traffic reach the hub? via MP-BGP?
