Hi
I need to set up an IPSec connection between 2 router for the traffic between 2 subnets behind. Besides, setting up the Phase 1, phase 2 including all the ACL, transform....., how should I set the route between the subnet? static route or eigrp? How should I set the access list to let the routing protocol get through the IPSec?
Thanks
create an ipsec encrypted gre tunnel betweeen the routers in order to exchange dynamic routing information, your ipsec-isakmp ACL will handle the LAN to LAN traffic over the tunnel
Is that means, if I just set up the Phase 1 and phase 2 and the eigrp, but no other things; the routing protocol will not go through. Then, the empty routing table is not able to direct the packets to the correct hop. Am I right?
Thanks

Yes. IPSec is IP only, no multicast. Since EIGRP uses multicast to exchange routing info, it won't work. As suggested, the solution is IPSec + GRE.
