Key Concepts

  1. Subnetting
  • CIDR: Efficient IP address allocation.
  • Subnet Masks: Define the IP range of a subnet.
  1. VLANs
  • Purpose: Isolate and manage network traffic.
  • Configuration: Tagged vs. untagged VLANs.
  1. Routing Protocols
  • OSPF: Dynamic protocol for intra-domain routing.
  • BGP: Protocol for inter-domain routing.
  • EIGRP: Cisco’s advanced routing protocol.
  1. Network Security
  • Firewalls: Protect against unauthorized access.
  • VPNs: Securely connect remote devices to networks.
  • IDS/IPS: Detect and prevent network intrusions.
