What I thought...
I am setting up all my branch servers as distrubution points so local clients download updates from their local servers instead of back at the main office. All the main office will do is push out the updates to the branch servers in the mornings. In order for updates to DL to branch servers using SEPM, All I have to do is add the server locations in SEPM/ADMIN/Local Site Properties/LiveUpdate and add the source servers, correct?
