I am working in company and they want to implement below thing, need ur help?in our branch there is one router and one unmanagable D link switch..OK...Router is connected to switch and switch is connected to Pc. and PC's default gateway is routers interface that is connecte to switch....NOW we have two WAN link one is coming from Tulip service provider and terminated on the router....and the other VSAT link is directly terminated to the LAN D link switch..so the problem is when my tulip link goes down then we have to change the gateway of all PC to divert the traffic from VSAT link. so I need a configuration on router so that we can switch over to
The only way I could think of is to change the switch to act as layer-3 switch.
You would set the PCs default GW to the SVI interface on the switch. then the switch could have HSRP , VRRP between the router , vasat router and the switch. Or the switch itself could have 2 routes pointing to the VSAT and the router as its next-hop with one be the prefered path.
This way, the switch would detect a failure on the upstream next-hop and would route the traffic across the desired path. therfore.
To achieve the desire you can also go Serial cable for VSAT , which you can connect to Routers serial interface port if you have two serial interfaces on router, after which you can configure higher metric route toward Vsat serial interface and primary towards ISP network.This cable is like normal V.35 cable and can be extended from VSAT IDU to Serial interface called V.24 .......As for as your LAN IPs are concerned you can configure same LAN IP pools for ISP and Vsat connectivity (If you don't have any limitations).
Can i use the same LAN subnet ip for serial interface where i connect Vsat IDU. and suppose if don't have then can i use WIC card....and is there any possiblity to use fast ethernet port. if yes then can i use the same subnet ip becaus my vsat ip is the ip from LAN subnet range.

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.
