How Does Scope Relate to SLP?

Communications Server scope relates directly to SLP scope. Therefore, SLP Service Agents and Directory Agents need to reside in the network that support these configured scopes. If you plan to allow clients to locate services based on scopes, keep in mind how scope relates to the network as a whole. If there are unscoped services in a network where scopes are also used, then these services are eligible to satisfy any scoped requests, which can potentially put a burden on those service agents and directory agents that support the unscoped services. For this reason, we recommend that every reachable server either have scope configured, or no server has scope configured. If directory agents are to be used in the site network (for upward scaling), then they should be configured to handle the same scopes as are configured for the servers. In addition, if unscoped services are to be used in networks with directory agents, at least one unscoped directory agent should be set up.
