Advertise ibgp routes over bgp with Palo alto

I have two sites that are similar, Palo alto fw behind a Cisco router. These two sites have a radio link between the two firewalls. The virtual routers in the firewalls have ebgp connection to their respective routers. The firewalls also have ibgp peering over the radio link. The firewalls have learned the ibgp routes for all of the virtual routers on each fw. The problem is, we want the traffic to go from one site through the radio to the other site's router. The fw is not advertising the ibgp route into ebgp to route. How do I get the Palo Alto fw to advertise the ibgp route?
