I have One Mikrotik router running router OS v6.1. I have One ISP connected to it but i recently got another ISP as backup. I want to connect the second ISP to the router in such a way that if the first ISP fails, the second one will kick in immediately. The link from both ISPs are ethernet links> Does anybody have any idea how to do this ?.

It wasnt that difficult to figure out once i went into the Mikrotik router. I just configured 2 static routes pointing towards the ISPs with different administrative distances. The main ISP with a lower administrative distance and a ping check on it so that once it goes down, the second ISP kicks in. To this, i logged into the Mikrotik router with winbox and went to IP tab. I chose routes from the drop down menu. The rest was self explanatory. After configuring it, i pulled the cable from ISP1 and PCs on the LAN were still able to surf the internet. I ran a tracert 188.8.131.52 which returned the backup ISP's router. I plugged the cable from ISP1 back into the router and immediately ran a tracer 184.108.40.206 which returned ISP1's router. Thanks everybody for your help.
it was my problem too. you should create tow static route: one of them referred to ISP1 and another to ISP2 , but ISP1's distance is 1 and ISP2's distance is 2. in this situation all client go out through ISP1 and if ISP1 is failed it is transferred to ISP2 . I wish you good luck.
