WebAs IGP is quite chatty (i.e. in fact not designed for handling a large number of routes), one can say IGP is an intra-AS protocol and cares about the internal network (topology) and abstracted from external/global network, but it does have provision to leak few global prefixes in the IGP domain. WebTo solve this, IGP is used in the ISP network to exchange specific topology information for reaching the next-hops within the ISP core. BGP advertises the external prefix with next-hop and IGP advertises the route to reach the next-hop. IGP handles all internal routes and BGP handles all global internet routes.
