Default Route Information –
• Originate Default Route – Generates a default external route into an
autonomous system. Note that the AS Boundary Router field must be
enabled, and the Advertise Default Route field properly configured.
(Default: Disabled)
• Advertise Default Route – The router can advertise a default external
route into the autonomous system (AS). (Options: NotAlways, Always;
Default: NotAlways)
-
Always – The router will advertise itself as a default external route for
the AS, even if a default external route does not actually exist.
- NotAlways – It can only advertise a default external route into the AS
if it has been configured to import external routes via RIP or static
configuration, and such a route is known. (See “Redistributing
External Routes” on page 3-327.)
• External Metric Type – The external link type used to advertise the
default route. Type 1 route advertisements add the internal cost to the
external route metric. Type 2 routes do not add the internal cost metric.
When comparing Type 2 routes, the internal cost is only used as a
tie-breaker if several Type 2 routes have the same cost. (Default: Type 2)
• Default External Metric – The Metric assigned to the default route.
