I have a Cisco 1811 wired router which i would like to configure WAN redundancy. But i do not have the IOS that has that capability. Where should i search and what should i search for. My ios version is 12.4(2)t. Should i be looking for ios with BGP as the routing protocol to make is possible?
12.4 is the latest version, you need to search for IOS release that has advanced IP services that support BGP for your hardware. This can be done at cisco site. However as for your redundancy you may not even need to run BGP for that. BGP is generally useful for multi homed connections to ISP's or if you are establishing peering with ISP/NSP.
Depending on your how your WAN sites are interconnected, what type of circuit is the ISP delivering the WAN interconnects etc etc... depending on all those you can run OSPF EIGRP for next-hop redundancy....
