Notifying Default Route

When a router uses redistributed routes it becomes an ASBR. ASBR
does not automatically advertise the default route to the whole
OSPF area by default.

Configuring Virtual Link

All areas on an OSPF network must directly connect to the back-
bone area, which will set a limit to the layout of areas especially
when the network is very large. To overcome this problem, a vir-
tual link can be used to connect a remote area to the backbone
area through another area. The area that the virtual link crosses
must have complete routing information, so it cannot be a stub
area.
area < area-id> virtual-link
Redistributing Other Routing
Protocols
Different dynamic routing protocols can share routing information
through route redistribution. In OSPF the routing information of
other routing protocols is the external routing information of an AS.
Only when the AS's external routing information is redistributed to
OSPF then it can spread it to the whole OSPF network.
