Description When the router is in an overload state, the router is used only if there is no other router to reach the
destination. This command configures the IGP upon bootup in the overload state until one of the
following events occur:
• The timeout timer expires.
• A manual override of the current overload state is entered with the no overload command.
The no overload command does not affect the overload-on-boot function.
The no form of the command removes the overload-on-boot functionality from the configuration.
Default no overload-on-boot
Parameters timeout seconds — Specifies the number of seconds to reset overloading.
Values 60 —1800

preference
Syntax preference preference
no preference
Context config>service>vprn>ospf
This command configures the preference for OSPF internal routes.
A route can be learned by the router from different protocols in which case the costs are not
comparable, when this occurs the preference is used to decide to which route will be used.
Different protocols should not be configured with the same preference, if this occurs the tiebreaker is
per the default preference table as defined in the following table. If multiple routes are learned with
an identical preference using the same protocol, the lowest cost route is used.
If multiple routes are learned with an identical preference using the same protocol and the costs
(metrics) are equal, then the decision of what route to use is determined by the configuration of the
ecmp in the config>router context.
The no form of the command reverts to the default value.
Default preference 10 — OSPF internal routes have a preference of 10.
Parameters preference — The preference for internal routes expressed as a decimal integer. Defaults for different
route types are listed in the following table.
