In the figure, only Router 5 is an ASBR.
The following parameters apply only to Autonomous System Boundary Routers .
Originate Default
Gateway
Advertisement Router will advertise itself as the Default Gateway (DG).
Default Gateway
External Metric Applies when Originate Default Gateway Advertisement is set to Yes . Defines the
metric that will be advertised by OSPF.
Default Gateway
External Metric-Type Applies when Originate Default Gateway Advertisement is set to Yes. For Type 1 , the
total metric of this route is composed of the internal metric (inside the autonomous
system) and the external metric (provided in the previous parameter). For
Type 2 , the
total metric of this route is the value provided in the previous parameter.
