you can do it by creating one BVI bridge virtual interface... and with the help of it you can add to the perticular interface into the bridge group... and multiple interface in single bridge group will act as single interface...
Abdullah asks how to use the 2 LAN interfaces together and Andy has provided what is probably the technically correct solution of bridging the 2 interfaces (though his solution does not allow the router to recognize or process IP on those interfaces). Devang adds the helpful suggestion of using IRB in creating a BVI interface which would allow the use of IP routing over those interfaces.
But I am not sure that either of these will really get what Abdullah is asking for. He describes in one interface and out the other. But in either of these solutions there is the matter of spanning tree. When these interfaces are bridged together spanning tree will have one of the interfaces in blocking mode and no user traffic will pass through it.
Perhaps Abdullah can help us understand what he is attempting to accomplish and then we might be able to provide better assistance.
My problem is I have 2651 router (Voip)which is having two fast ethernet ports. fast ethernet 0/0 pluged to the lan. I want to use the other port to proviide the lan to other device. I can do it with using a switch but it's no worthed. I want to use this port instead.
Am I correct in understanding that you want to connect a single device on the other fast ethernet port? Is it a requirement that this device be in the same subnet (same VLAN) as the other devices? It would be fairly simple to connect the device to the other fast ethernet port and create a different subnet, give the device an address in the different subnet, and the router will route between the two subnets. This could work ok. But trying to put both fast ethernet interfaces into the same subnet and the same VLAN is an issue as the previous posts have discussed.
I have one Voip router with two fast ethernet. The first ethernet (f0/0) connected to the LAN with Dynamic ip ( DHCP ). I want to use the other port (f0/1) to connect another device (e.g PC). I tried to bridge the both fast ethernet but it doesn't work. The connected device didn't take an IP.
I want to try the BVI bridge but i don't Know how could you or any body give me the commands
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!

I am going to design and build an LAN network under a tunnel underground with long distance between the switches.
I will have 2 Catalyst switches and 8 Industrial IE3000, and they will be connected with fiber.
