An IGP such as OSPF or IS-IS have a main role for exchange of routing information within each AS. BGP is very scalable and stable routing, therefore bgp in most cases is deployed to improve/enhanced the existing network.

BGP can scale to million of routes and multiple copies of the Internet route table.
