It seems to me that an offset list applied outbound
on one of the routers could make its routes less
attractive than the routes from the other router.
This should give you 1 primary set of routes and 1
backup set of routes. And does not require any
special configuration on the ASA.

Thanks!

Yes of course, if the ASA has to do EIGRP my suggestion is irrelevant. I
overlooked that somewhat since I'm not used to thinking about having
firewalls do dynamic routing. :-)

The HSRP thing would of course be with the ASA not participating in the
EIGRP. On the ASA side you would use static routes pointing at the HSRP
IP. On the router side you would use static routes pointing at the ASA
primary IP.
