Right now I have one ISP link. In future we are getting another ISP link. At present our all servers are using present ISP public IPs.
My doubt is even though getting second ISP link, if first link goes down, how second ISP route the traffic to our servers which are using first ISP public ISPs.
So we are planning to implement BGP on internet router. Then how to implement BGP on it. We didn't own public AS number.
