If you are running Oracle 5 you are still in the wrong forum.
This is CentOS 6.

Yes i agree but network admin could be the same feature across different flavours of Unixes , i guess

5 does not equal 6, and RHEL5 netrwork admin is not the same as RHEL6 network admin.

IMHO a NIC is always a physical device (even if it is a VM it is a vNIC) and not to be mistaken with VLAning.
[quote]if single machine has 4 NICs [physical and virtual lan] and another machine has 4 NICs[physical and virtual]
How do i make interaction between them say example
gateway : 192.168.1.1 nic0 of box1 to nic0 of box2 --done working ex: 192.168.1.12, 255.255.255.0, 192.168.1.13, 255.255.255.0,
vlan120 of box1 to vlan130 of box2 not working ex: 192.168.100.2, 255.255.255.0, 192.168.100.3, 255.255.255.0
box1#ping 192.168.1.13 -- works well
box1#ping 192.168.100.3 -- network unreachable[/quote]
If you need bonding I would connect the 4 NICs from both machines to a switch. Depending of the bonding you might have to talk to the network admins to set up link aggregation if required. The the ping does not work because, if you setup VLAN-Interfaces you add VLAN-tags (802.1q) to the ethernet-frame. If the tag does not match (as in your case 120 !equal 130) there won't be any communication. If the tags would match it would work. You probably also need the network guys to setup the switch to use the right VLAN-tags.
