ISP redundancy

[Ruben Harutyunyan]

Hi guys 

Need your advice , here is the scenario

I have an CISCO 2911 router and 2 ISP links  and really often problems with internet speed 

is there any way to track one ISP's performance lets say when  delays are high to force router to change on second ISP's link

Thank you!

I'm going to assume you are running a Cisco router that uses IOS or IOS-XE.  In which case, check out Pfr (Performance based routing).
