Specify a router as an Autonomous
System Boundary Router (ASBR).
An ASBR has at least one interface
into an external internetwork
(another autonomous system), such
as a non-OSPF network. The ASBR
redistributes non-OSPF network
information to the OSPF network,
and vice versa.
The
no form disables ASBR status.

Modify the metric type for external
routes to type1 or type2. The

The no form restores the default for
the specified external route.

SPF paths OSPF can use. The default
