type 1 external paths are preferred over type 2 external paths, using
cost only to break ties (RFC 2328).
◆ All routers in an OSPF routing domain should use the same RFC for
calculating summary routes.
◆ If there are any OSPF routers in an area exchanging summary
information (specifically, ABRs) which have not been upgraded to
OSPFv2, this command should be used on the newly upgraded OSPFv2
routers to ensure compatibility with routers still running older OSPFv2
code. Once all systems have been upgraded to newer OSPFv2 code, use
the no form of this command to restore compatibility for all systems
with RFC 2328.

default external route into the AS if it has been configured to import
external routes through other routing protocols or static routing, and
such a route is known. (See the redistribute command.)
