I have my current network where I am doing bridging over WAN using GRE and IRB. Works perfectly fine. I have a additional requirement whereby I need to use duplicate IP addressing scheme on the same router. I was looking at VRFs for such a implementation. I have seen a scenario on Cisco's site whereby they are implementing GRE Tunnel with VRF configuration. But is it possible to run bridging, GRE and VRF together. Any issues.
