I have two different links in my office (factory) to connect to Head office from factory. One is 3Mb and another one is 2Mb which is used only for backup purpose when the primary 3Mb goes down. Otherwise the backup 2Mb link remains useless. Both of them are provided by same vendor. I am thinking to aggregate these two different links bandwidth together. Both link will be live together and serves as a single one providing 5Mb at a time. When the primary 3Mb falls another one will route data packet to the destination and vice versa.
Now the question is it possible?? If possible how?
Please help with details answer with necessary links and if any devices needed.

Dear Sayeed ,
since both of your connections are from same ISP ,you can tell your ISP to make the load balancing for you. No need to do anything on your side
Let's say you have 8 public IP's from the ISP,devide them to two subnets and then tell ISP to route first subnet thru one link and second subnet through other link
the ISP side config will be as given below
***********************************8
ip sla monitor 16
type echo protocol ipIcmpEcho 10.100.110.210 source-ipaddr 10.100.110.209
ip sla monitor schedule 16 life forever start-time now
track 138 rtr 16 reachability
ip sla monitor 17
type echo protocol ipIcmpEcho 10.100.111.210 source-ipaddr 10.100.111.209
ip sla monitor schedule 17 life forever start-time now
track 138 rtr 16 reachability
track 139 rtr 17 reachability
ip route 78.87.87.0 255.255.255.252 10.100.110.210 track 138
ip route 78.87.87.4 255.255.255.252 10.100.111.210 track 139
ip route 78.87.87.0 255.255.255.248 10.100.111.210 200
ip route 78.87.87.0 255.255.255.248 10.100.110.210 200

what type of link coming to the factory... we are using a linksys RV042 aggregator for this kind of thing but that is in ADSL i think that can work with ur scenario also.. give a shot
