Hi Kiran

I am not sure I understand your problem?

Any Linux box with 2 NIC's and IP Forwarding enabled on those NIC's will route between the VLAN's.

i.e. NIC1 eth0 --> & IP Forwarding enabled

NIC2 eth1 --> & IP Forwarding enabled

Connect a cable from each NIC to a switch. Connect other equipment to each switch and give then the relevant IP addresses and default gateway information.

i.e. equipment connected to the switch which is connected to eth0 get IP addresses in the 172.16.0.x/24 subnet and as the default gateway.

Now equipment connected to each switch should be able to ping equipment connected to the opposite switch, which is on a different subnet.

Zebra is only required if you want to run routing protocols such as RIP or OSPF on Linux.

what you said is right.

i have a 2950 switch and i dont have a cisco router for Inter-VLAN Communication.i have a Linux box with 1 eth0 port.

Know i want to do eth0.1--for VLAN2 and eth0.3---for VLAN-3.

for that i need a router right so do u know any Linux based router which can do dot 1Q encapsulation .
