Route Selection section.
Enhanced IGRP uses three kinds of routes: internal, external, and summary. Internal routes are routes that are learned from Enhanced IGRP. External routes are routes that are learned from another protocol and then redistributed into Enhanced IGRP. Summary routes are routes that Enhanced IGRP may dynamically create due to auto summarization, or due to an explicit summary route configuration. Route selection is based on administrative distance. The default administrative distance for Enhanced IGRP is 90 (internal), 170 (external), or 5 (summary). For IGRP, the default administrative distance is 100 because internal Enhanced IGRP routes take precedence over IGRP routes, and IGRP routes are preferred to external Enhanced IGRP routes. | |

Anything redistributed into IGRP would be advertised as an exterior route...ie statics, another AS or another routing protocol.
