Routing loop redistributing a longer prefix static route
I have what seems a simple problem and I must be overlooking a simple solution.
Please see the attached diagram for details. I have 3 typical routers all successfully participating in a single EIGRP process. Currently, all traffic flows through the higher bandwidth connections as it should. My goal is to have all traffic from a single host A to single host B go a different route via the T1.
All this is shown in my attached diagram. I am trying to make this traffic flow change by creating a static route in Router B which is redistributed into EIGRP.
The problem is a routing loop is formed because Router C thinks that the more specific route is at Router A when it really is on its local Connected interface.
How can I have Router C ignore/overcome the more specific route to Host B and use its connected interface? I am open to a better way to make this happen, too.
I have tried a distribute-list out filter at Router A to stop the advertisement of the static route (within EIGRP). This did not work because Router C now has a route back to Router B for the more specific route. (Note: this is not indicated in the diagram)
