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:
If a route is imported to the BGP routing table through the import-route command,
its Origin attribute is Incomplete.
The network segment route to be advertised must be in the local IP routing table.
You can use routing policy to control route advertising with more flexibility.
The Origin attribute of the network segment routes advertised to BGP routing table
through the network command is IGP.
