Hello,
Please can somebody explain to me when it is necessary to use GRE tunnel for
IPSEC when using OSPF. I have seen examples where they used OSPF without GRE
tunnel and also seen were they used OSPF with GRE tunnel. Which is correct.
I have read that OSPF is not supported natively of IPSEC? Does this mean you
have to use GRE all the time you have OSPF?

Please help.

Peter
