I am currently working on a solution where we need to route IP addresses directly via an interface rather than a gateway/next hop IP address.
I have very limited exposure to Cisco routers and my question is;
Is it possible to configure alternate routes if routing directly via an interface i.e. try interface-1 and then interface-2 (if the cal cannot be placed via interface-1).
Apologies if this sounds to trivial a question to ask!
The model of router that we are thinking of using is the 3640.
Thank you.

This is exactly what PBR (policy Based Routing) is
about .
In brief :
U apply the PBR to an interface ,where
all input packet are screened to a filter list
(ACL) , If match is found U specify which
interface(s) to use .
If no match the router return to the normal
DBR (Destination Based Routing)
pls refer to cisco web to get the detailes (
just search for "policy-based routing" ) .

you can configure a floatint static route for one interface. Lets say , like u said, that you have two interfaces on a router via which you want routing, if one fails, the other comes into action, rite?
I am assuming you are aware of your destination network i.e. its not the internet you are routing to. Well, you can use a dynamic routing protocol for one interface, configure the other interface to use a static or default route. Then that static or default route can be given a higher admnin distance and can also be redistributed into your dynamic routing table, for other routers to know about it.
