I have one cisco 1700 series router with 2T WAN interface card,currently we using only one WAN interface point to point link,speed 1 mbps. I have one 2 mbps RF link witch is directly terminate on LAN switch and router's fastethernet is also connecting the same switch, both link use for data. If one link goes down we have to change ip addresses of the pcs manually.
My question is that can I connect this RF link to second WAN port of cisco 1700 router and do the routing? So if one link goes down no need to change ip address of pc.
Point to point leased line link and RF link each are of different service providers
