Module 6: Network Addressing and Subnetting

• IP Addressing Basics
  Review of IP addressing concepts, including private and public IP addresses, subnetting, and CIDR notation.

• Subnetting and VLSM
  How to subnet a network and apply Variable Length Subnet Masking (VLSM) for efficient IP address allocation.

• Configuring Subnets on Routers and Switches
  Assigning IP addresses to routers and switches, and configuring interfaces for each subnet.

• Address Assignment Protocols
  Configuring DHCP (Dynamic Host Configuration Protocol) on routers to assign IP addresses dynamically to devices on the network.

---

Module 7: Advanced Configuration and Management

• Advanced Routing Protocols
  Configuring advanced routing protocols like BGP (Border Gateway Protocol) for inter-domain routing, and using route redistribution.

• Quality of Service (QoS)
  Configuring QoS to manage bandwidth and prioritize traffic to ensure optimal network performance.

• Network Monitoring and Management
  Introduction to SNMP (Simple Network Management Protocol), NetFlow, and other network management protocols to monitor network performance and health.

• Configuration Management and Backups
  Best practices for managing device configurations, including using TFTP/FTP for backup, and version control systems for device configurations.
