Note RTF’s routing table which indicates that networks local to
AS300 such as 192.208.10.0 are to be reached via RTB. Other known
networks such as 200.200.0.0 are to be reached via RTA. The
gateway of last resort is set to RTB. In case something
happens to the connection between RTB and RTD, then the default
advertised by RTA will kick in with a metric of 2000.
