I have 2 ethernet cards at my server,OEL5.5. One is for Public LAN and another is for private to install Oracle RAC. I am facing the following problem
[root@itdb1 ~]# ping 192.168.165.120

When I want to ping any IP like 192.168.163.X, it is using my second ethernet card which is configured for private VLAN/Interconnect.
How can i get rid of this problem?
Regards
What's your routing table look like?
