Hi Marcelo ,

idea ?

As you will be served by two different ISPs , the optimum solution is use
BGP .

With Netflow you will get a clear view of your traffic distribution (
volumes destination , source , application , etc )  and based on your
analysis to the output of the netflow  you can implement ur traffic policy

With ur  ISPs you have two 3 options
  a.. Receive full BGP table
  b.. Partial with default
  c.. just defaults
In ur case ( Cisco 3600 ) , you can receive just default and configure
Multipath // Maximum-Paths 2 you will achieve loadbalancing upstream
for down stream you can break ur prefixes into 2 groups ( approximately
traffic destined to each one equal ) and this can be discovered by netflow ,
one group preferred from ISP1 and the other preferred from ISP2 and that by
using AS-PREPEND .

As for CISCO 7200 router with the edge router , you may run RIP , or IGRP or
just configure static routes .
