[f-nsp] Policy based routing question

Ok,

I now have a little more idea on what is causing my problems.  Its VRRP
causing my ip policy route-map to not work.  When I remove VRRP from a VLAN
I am testing with my route-map works properly but stops working when I
re-apply the VRRP Config.

Any ideas on why VRRP would break a ip policy route-map?

Thanks everyone

Joe
