Routing: OSPF routing inside GRE tunnels.
GRE tunnels inside IPSEC tunnels with OSPF routing.......
GRE tunnel support is a separate feature request. In the mean-time, Site-to-site RED tunnels may be used, rather than IPsec tunnels, to achieve the same effect in a simpler manner.

I do not agree as third-party WAN vendors only support GRE tunnels.

This should be merged with this thread that is asking for the same thing but with BGP:
BGP inside GRE is needed as well.

please keep in mind this idea not only OSPF routing

This makes easier to do interop with Cisco who are using IPsec over GRE and doing OSPF routing for failover, like us.
