Layer 2 Technologies: This topic covers a range of Ethernet-based technologies and protocols, including spanning tree protocols (STP), virtual LANs (VLANs), link aggregation techniques, and various bridge configurations. These sub-topics focus on network efficiency, load balancing, and secure connectivity.
IPv4/IPv6 Unicast: Addressing schemes, subnetting, and routing protocols for IPv4 and IPv6 unicast transmissions are covered here. This section also includes tunneling and migration techniques, as well as the functionality protocols unique to IPv6.
MPLS VPN: This main topic centers on Multiprotocol Label Switching (MPLS) and its applications in virtual private networks (VPNs). It covers MPLS fundamentals, Layer 3 VPN configurations, and inter-autonomous system (AS) MPLS VPN connectivity.
IPv4/IPv6 Multicast: The section briefly touches on IPv4 and IPv6 multicast capabilities, which facilitate group communications and efficient data transmission to multiple recipients.
Network Security: A range of security measures and protocols are discussed here, including access control lists (ACLs), authentication protocols, network address translation (NAT), and device access control.
