I assume it is the Internet connection that you want to make redundant.

If you have any inbound connections, you will have to have a router 
running BGP and your two providers will have to co-operate to get this 
setup and working properly. We have two connections from the same 
provider and it did not cost us anything to add BGP support.

The router can be a dedicated device such as from Cisco, et al or can be 
a Linux-based machine running Zebra.

There are other "budget" methods to create a form of redundancy but they 
have drawbacks (see post from GH)
