overload-include-stub
Syntax [no] overload-include-stub
Context config>service>vprn>ospf
Description This command is used to to determine if the OSPF stub networks should be advertised with a 
maximum metric value when the system goes into overload state for any reason. When enabled, the 
system uses the maximum metric value. When this command is enabled and the router is in overload, 
all stub interfaces, including loopback and system interfaces, will be advertised at the maximum 
metric.
Default no overload-include-stub
overload-on-boot
Syntax overload-on-boot [timeout seconds]
no overload
Context config>service>vprn>ospf
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.
