External NIC cards not pinging with each other in RHEL 5.1

We have a setup of two nodes which has two NIC cards in each. One is built in and another is D-Link (external NIC card). We are unable to ping to the external NIC cards in both. Eg: Node A has two IPs 192.168.1.10 (eth0) and 192.168.2.10 (eth1) and Node B has two IPs 192.168.1.20 (eth0) and 192.168.2.20 (eth1). These setup has two switches, where 192.168.1.10 and 192.168.1.20 is connected to Switch A, 192.168.2.10 and 192.168.2.20 is connected to Switch B.

The problem here is from 192.168.1.10 is able to ping 192.168.1.20 but not to 192.168.2.20 same with the Node B 192.168.1.20 is able to ping 192.168.1.10 but not 192.168.2.10. when all are placed in same network then all IPs are pinging with each other.

All Linux gurus please help me .. pls treat this request as high prioprity!!
