Scenario is as follows:
1 PIX that will be utilizing an IPSEC tunnel to an ASA at another site.
1 router behind the PIX needs to tunnel GRE to a router behind the ASA. (for EIGRP routing updates)
This will be utilized in a DR scenario where our core connection goes away.
Any assistance in pointing me in the right direction is appreciated. I know there are some issues routing GRE over IPSEC and I'd like to avoid them if possible.
