Iwan,
Staying away from any argument..
There is a third way to do this that does not use floating statics. That is
to use route a route map.
NOTE: I don't have a router in front of me right now so there could be a
few errors in the commands.. But it should look something like this.
------
! assuming the traffic is coming from e0 apply a route map to it
Interface e0
ip policy route-map FR_backup
! the router map will send the traffic specified traffic to the frame relay
interface (S0) UNLESS it is down. Then it is sent to the dialup interface
(BRI0)
route-map FR_backup
match ip address 105
set interface Serial0 BRI0
! specific the traffic into e0 that would go out the FR interface match
the route map
access-list 105 permit ......
