Cisco :: Route traffic on the basis of source subnets

Hi there,

Guys I really need your help..

Actually I have Cisco 2800 series router that has two fast Ethernet interfaces, one of them is defined as internal network and the other one is as external. In our network there almost 15 subnets, and have two external links.
I want to route some selected VLANs to first external link, and rest of them should go through second external link.

For example:

172.30.0.0/24
172.30.1.0/24
172.30.2.0/24
172.30.3.0/24
172.30.4.0/24
172.30.5.0/24
172.30.6.0/24
(The above VLANs should be routed to router A which is my first ISP)


172.30.7.0/24
172.30.8.0/24
172.30.9.0/24
172.30.10.0/24
172.30.11.0/24
172.30.12.0/24
172.30.13.0/24
172.30.14.0/24
172.30.15.0/24
(The above VLANs should be routed to router B which is my second ISP)

All VLANS are connected to fast Ethernet 0/0, and both ISPs will be connected to fast Ethernet 0/1

My internal network has no issues; on external interface (fast Ethernet 0/1) I have defined networks for both ISPs (because I am having static pool of IPs)

Now my main question is how I can configure my Cisco router to route traffic on the basis of source subnets.

Ip route command is used to route traffic on destination basis. I am getting extremely confused in this thing.

Please help me out!
