Configuring SCCM Discovery
Configure discovery methods to find resources to manage from from network and Active Directory. Discovery creates a discovery data record (DDR) for each discovered object and stores this information in the SCCM database. When a resource is discovered the information about the resource is put in a file that is referred to as a discovery data record (DDR).

Active Directory Forest Discovery – This method discovers Active Directory sites and subnets.
Active Directory Group Discovery – This method discovers groups from the defined location in the Active Directory.
Active Directory System Discovery –This method discovers the computers in your organization from specified AD locations.
Configuration Manager Active Directory User Discovery – This Discovery process discovers the user accounts from your Active Directory domain.
HeartBeat Discovery – This is the only discovery method that is enabled by default. The HeartBeat Discovery runs on every SCCM client and is used by Active Configuration Manager clients to update their discovery records in the database. Furthermore the records are sent to the management point in specified duration of time.
Network Discovery – The Network Discovery searches your network infrastructure for network devices that have an IP address. It can search the domains, SNMP devices and DHCP servers to find the resources. This includes printers, routers, and bridges.
Below is the discovery methods from Console

Configure SCCM Boundaries
As per Microsoft, a boundary is a network location on the intranet that can contain one or more devices that you want to manage. Boundaries can be either an IP subnet, Active Directory site name, IPv6 Prefix, or an IP address range.
To use a boundary, you must add the boundary to one or more boundary groups. Boundary groups are collections of boundaries. By using boundary groups, clients on the intranet can find an assigned site. In addition to that they can locate content such as applications, software updates, and operating system images. Active Directory Forest Discovery discovers boundaries automatically.
To create boundries in SCCM,
Open the SCCM Console-Go to Administration / Hierarchy Configuration / Boundary-Right-click Boundaries and select Create Boundary
Here i have used Active Directive Site
Here boundary has been created and reflected in Console
