  2. I thought since there is no keyword “always” in the command, the router will only advertise a default route if it actually has one in its routing table. Otherwise, it won’t

  3. Agreed with Wanna-Be-CCIE that without “ALWAYS” keyword, the router will not advertise default route if its already not in routing table.
