I believe that's correct. The remote side could have just one area configured. The core network could then provide area 0 and connectivity to other areas.
You could also have just one area completely- say area 1- across the entire network - as long as no other areas exist. If there are more than one areas, then you need an area 0 router to provide the ABR functionality and generate the Summary LSAs. I believe an exception would be - you could have multiple areas without area 0 connected by an MPLS VPN - since it provides the 'super backbone'. > From: [email protected] > To: [email protected] > Date: Mon, 3 Mar 2014 16:16:48 -0500 > Subject: [OSL | CCIE_RS] OSPF AREA > > Hi, > > This is probably a dumb question but I am confused.. can you have just one > ospf area configured, for example only area 1?
