SLP Service Scope Option (Option 79)
Services are grouped together using 'scopes'. These are strings that identify a set of services that form an
administrative grouping. Service Agents (SAs) and Directory Agents (DAs) are always assigned a scope
string.
A User Agent (UA) is normally assigned a scope string (in which case the User Agent will only be able
to discover that particular grouping of services). This allows a network administrator to provision
services to users. The use of scopes also allows the administrator to scale SLP deployments to larger
networks.
The Scope-List String is a comma-delimited list of the scopes that a SLP Agent is configured to use. The
Length value must include one for the 'Mandatory' byte.
The 'Mandatory' byte determines whether SLP Agents override their static configuration for scopes with
the <Scope List> string provided by the option. This allows DHCP administrators to implement a policy
of assigning a set of scopes to Agents for service provision. If the Mandatory byte is 0, static
configuration takes precedence over the DHCP provided scope list. If the Mandatory byte is 1, the
<Scope List> provided in this option must be used by the SLP Agent.
The Scope List String usage is defined in the SLPv2 specification (RFC2608).
