I am currently trying to advertise routes to our VPN connected sites using EIGRP on our 55xx firewalls. For most sites RRI is our first option since it provides the most dynamic routing in the event of a failover for the remote sites.
The problem is that some of our remote sites are not manned and its my understanding that if the tunnel drops after a certain time the reverse route will drop and routing will not come back up unless initiated by the remote side.
I am looking for something more permanent, other than a static route on the local router, that will "hold" this route in place in case the VPN needs to be brought up from the local side.
Our goal is removal of all static routes on the internal LAN.
