• SPF Hold Time (seconds) – The hold time between making two
consecutive shortest path first (SPF) calculations. (Range: 0-65535;
Default: 10)
• Area Numbers – The number of OSPF areas configured on this router.
(This parameter is read only.)
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 through RIP
or static configuration, and such a route is known. (See
“Redistributing External Routes” on page 460.)
• 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.
(Range: 1-65535; Default: 10)
Note: The AS Boundary Router and Default Route Information parameters
can be configured with the
default-information originate
