Hello Mani,

In general, RFC 2328 doesn't deal with origination of external
defaults or the redistribution (aka, import) of routes from
other protocols. However, it does describe the composition of
an OSPF AS external LSA for a default route.

Most OSPF implementations provide the capability to
originate a default route under configuration control.

It depends on the situation. In any case, this should be a
configurable option.
