Indirect Source Advertisement into BGP

BGP can advertise routes learned from multiple sources, such as static routes, EIGRP, OSPF and more.

Every network learned from an indirect sourced needs to be advertised via it’s own network statement, though this can seem tedious for many networks

router bgp 65200
 network 192.168.1.0 mask 255.255.255.0
 network 192.168.2.0 mask 255.255.255.0
...

Route summarisation is a valid method of reducing this overhead.
