Change interface virtual router cause network down

My network has 2 outgoing data lines. Using one virtual router and set static default route for the 2 interfaces. The 1st interface has its Metric set to higher priority. As I want to divide the traffic. Some zones were force to use the 2nd interface by setting "Police Based Forwarding".

Above settings work until I found that the 2nd interface was unable to reach internet due to asymmetric routing. So I create a new virtual router and a static default route for the 2nd interface.With the new virtual router. The 2nd interface can contact from/to internet. But those zones rely on it to reach internet were all down.

Some policies (Security, NAT, PBF) were review. I still have no idea what cause the problem.

Are the interfaces associated with the down zones included in the second VR configuration?

hello rmfalconer,

Yes. When I create the new VR. I add the 2nd interface to this VR + the new default route.

No policies changed. Those zones are associate to the 2nd interface (in PBF). This work before even using only 1 VR.
