Could you be more specific with what you are trying to do here?

You cannot add another router with the same address to the same subnet, but you could use HSRP for redundancy to have a virtual address that both routers shared on the same subnet. This may or may not be what you are looking to accomplish.

Please post with more details.

As there are no empty serial ports are available,I want to place another router and provide the conectivity.

How ever we can purchase the NM 4T which will take more time to get approvals.

Meanwhile can I connect the other router to the switch where the main router was connected and assign the other free ip from the same subnet which is using for the 1st router fastethernet and route the traffic through the main router.

1. Yes, you can connect another router to the switch & assign IP from same subnet.

2. If you are running routing protocol between the 2 routers & the switch, then no manual intervention required for route selection.

3. However, if you are using static routes then you have to add a couple of routes on the switch & old router for destinations connected to new switch.

You may revert for further assistance.

pls rate if helped.
