I have setup an IPSEC GRE Tunnel between two routers over a wireless connection and running EIRGP routing protocol over this link. The problem I am having is that the GRE tunnel stays up all the time regardless of whether the wireless connection is available. If the wireless connection goes down the GRE tunnel stays up even if I don't have connectivity over the encrypted link.
When the link goes down, my EIGRP neighbors drop as expected, however when the wireless link comes back up, my eigrp neighbors and routes do not re-establish automatically. They only re-establish if I manually shutdown the GRE tunnel and then bring it back up.
What can I do to address these two issues that I think are related. I would like the GRE tunnels to track the actual connectivity and the EIGRP routes to re-establish automatically.
