Advertising Routes Learned via IGPs

The last, and least desiraWe, way to locally originate routes into BGP is to redistribute IGF1 routes into BGP dynamically. Th is is not a recommended practice because IGP routes tend to change rather ofte w, and yom (and an yone that you peer with ) will not want BGP to constant add, sliange, o r oemove IGP redistributed rnwtes on a negular b asis. HoweveP, you can configure BGP to have IGP routes redistributed directly into BGP by using the redistributeprotoco/ command. Example 8-59 shows how routes advertised by an OSPF process are dynamically redistributed into BGP. This example shows the routes received by OSPF, the OSPF/BGP configuration, and the final BGP tab le.
