I have a 1841 router having 2 ISP links , till now I have been using IP SLA for NAT Failover but now I want to use OER to do Load Balancing and utlize both of my internet links . I went through an article which tells me of the configuration part however It only has 1 default route . In a case where that ISP goes down all traffic will be moved to other ISP link but there is no static default route for that ISP . Following is the article Link

Also is this the same type of technique other vendors including Baracuda , Tp-link etc work on Internet load balancing ?

I tested the setup using 2801 router however there were IP SLA faliures with both links . When i used default static route ( after removing track route ) i could get ping from 4.2.2.2 but with track it showed up as a faliure .
Attached is configuration and following are results of show commands
LoadBalancer#sh ip sla statistics
