5.4.2 Importing Routes
With BGP employed, an AS can send its interior routing information to its neighbor ASs.
However, the interior routing information is not generated by BGP, it is obtained by
importing IGP routing information to BGP routing table. Once IGP routing information is
imported to BGP routing table, it is advertised to BGP peers. You can filter IGP routing
information by routing protocols before the IGP routing information is imported to BGP
routing table.

Caution:
z If a route is imported to the BGP routing table through the import-route command,

through the network command is IGP.
