we are getting a new ISP whereby we get 2 E1 links in to our building. both these plug in to the same router and are load balanced (non-BGP). We were wondering if it is possible, without the use of BGP (or just using private BGP routes within our own network), to add a second router to the configuration... plug one line in to each router and have a floating ip address between the 2 on the internal interfaces... but still load balance the 2 lines. obviously this means if one router fails we will loose a link. also if one of the links dies, all traffic should be routed through the router that still has the active line.
please note the pair of routers should be in a spanning tree config with 2 cisco pix
