It will be really great if you can provide us little bit more information about your topology and protocol runing in your network as well as between you and your providers, as well as the subnets in your network...

Hi Devang
thank u about ur response , i attached my topology , my lan network 10.0.0.0 i want to divide this network to two groups , the first group routed to the 1 st isp and the second group routed to the second isp and if the first isp link fail the first group go to the second isp , i read that route map can divide the lan network to two groups and route each group to each isp but if the link fail the users group will bue routed to the second isp ???? and if it can't how can i achieve that ???
note : the protocol used between us and isp is RIPv2

There are a couple of ways.
Do you have one or two ethernet iterfaces?
If you have two then you can separate your groups there, then allow each group on a different block access to the internet out a specific interface there and also failover in the event one link goes down.
You would set up policy based routing. If traffic from one subnet enters the router sent it out one of the outbound interfaces.
