SPF runs in small routing domains
We should not be suggesting that SPF is the Internet-wide routing algorithm, or, indeed, that there is any one algorithm. SPF is quite effective in networks, or hierarchical subareas of networks. Even real-world intradomain routing protocols such as OSPF use distance vector routing for their inter-area and external routes. The overall Internet (and large private system) Border Gateway Protocol uses path vector routing with a considerable number of policy extensions, the policy so dominating that BGP is not infrequently called a reachability protocol rather than a routing protocol.
