How are the routes outside ara 1 going to appear, as i L2 or i *L1 in the routing table of router A and through which interface. Please see picture attached.
it will appear as L2 as it is connecetd to other area.
*L1 are used for default gateway. Suppose you have one router E connected to A and one router F to C. As E and F are in different area and are like stub area in OSPF and need a default gateway to reach out to F. When you see the ip route in E & F you will get an entry like *L1.
