• This will advertise a default route to the BGP peer without a default route present in the RIB. The default route will be created to be announced to the BGP neighbor only.

Reference

• BGP – default-originate-routemap purpose

• Managing the ‘capability-default-originate’ BGP command

• Use BGP Weight attribute to prefer default route received from neighbor over ‘capability-default-originate’ route
