I have a single Cisco 3845 as my Internet router. Currently I have two 100 Mbps Ethernet circuits from the same ISP, and both of those circuits terminate on the same router at the ISP. We have BGP in place for load balancing and failover. I am changing out one of the two circuits so that I'll have diverse routes into my core, so looking forward the two circuits will still terminate on the same single router on my end but will terminate on two different routers at the ISP in different cities. The ISP is telling me they can no longer offer me BGP as a load balancing solution. What options do I have to ensure I have load balancing and failover (if one of the two circuits fail) of these circuits?
