Subject: [PATCH] lib: Routemap is not getting applied upon changing the
routemap action
Description:
This looks broken after NB changes in routemap. When routemap
action modified from permit to deny, it is expected to apply
the new action on the filtered routes before the action in the
routemap data structure has been changed. But currently this is
not handled by the corresponding northbound API.
