Can anyone please explain me the use of this policy?
You can't receive the route from protocol static (it's statically configured not advertised or received)
you can't use this policy as an import-policy because we received the route from dynamic protocol not static.
You can apply this policy as an export policy but the preference value is locally significant so no use of "then preference" statement
You can apply this policy in "instance-import" but "from instance <instance name>" statement is missing. without which this policy will not work.
It could be a childish question but I am curious to know.
Is there any other use of this policy?
