Hello @akazadmanik095 ,
we need more info to able to help you:
Multihomed ISR 4221
Are using full speed 1 GE links to each provider ?
one provider can be providing the best path to some of your business partners .
I guess you are receving only a default route and selected routes as I do no expect your router to be able to support full BGP tables.
