The doc. should fix the problem, it was because the router is ourside the firewall and not the termination points of the VPN. You simple build the GRE between two routers, ensure the traffic of the GRE tunnel will pass via IPSEC tunnel, and enable the OSPF (or other routing protocol or application) in the GRE tunnel. Then it will be no problem.
The routers just treat the connection to the firewall is a path to remote side.
However, if you want to use router for the IPSEC tunnel at the same time, it should work too but it is more complicated and difficult to troubleshoot. And you already have the IPSEC at firewall, so just keep it and modify the router is simplier.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
