Luke You must already have "APPN functionality" since you have a Network Node and 7 End Nodes.
In addition, you are already participating in border node behaviour. The adjacent topology subnetworks to which you are connected must already be performing border node functions. You participle in that, when you initiate a session with an LU in one of the adjacent topology subnetworks, you search each of the adjacent Network Nodes which appear as End Nodes - which have allowed themselves to be searched - to your Network Node. Also, when an LU in one of the adjacent topology subnetworks initiates a session with an LU in your topology subnetwork, the search emerges from one of the Network Nodes adjacent to your Network Node although the search appears to be coming from an End Node. When you change your Network Node also to appear to be a border node, and with BNDYN=FULL, processing in your network won't change at all. The main reason is that your have only one Network Node and so the logic affecting searches hasn't any chance to be any different. There may be some effects in the adjacent topology subnetworks so you should inform all your partners that you are making the change so they can look out for changes - although there shouldn't be any problems. The more you add Network Nodes to your topology subnetwork and the more these Network Nodes also become border nodes, the more you will need to get to grips with the implementation of border node architecture in VTAM. If you'd like to have some reading to give you greater confidence in what you are already doing and how this is changed when you "come clean" and admit your Network Node really is a border node, you can check out Chapter 6.
