IP class refers to the range of IP addresses that are available for use in a network.
There are five classes of IP addresses: A, B, C, D, and E.
Class A addresses are used for large networks, while class B and C addresses are used for medium and small networks respectively.
Class D addresses are used for multicasting, and class E addresses are reserved for future use.
The class of an IP address is determined by the first f...

BGP stands for Border Gateway Protocol.
It is an exterior gateway protocol used for inter-domain routing.
BGP allows routers in different autonomous systems to exchange routing information.
It helps in determining the best path for data packets to reach their destination.
BGP is used by internet service providers (I...

A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
Firewall acts as a barrier between a trusted internal network and an untrusted external network.
It examines network packets and filters them based on rules to allow or block traffic.
Firewalls can be hardware-based or software-based.
Examples of firewalls include Cisco ASA, Palo A

STP (Spanning Tree Protocol) is used to prevent loops in a network by blocking redundant paths between switches.
STP elects a root bridge to serve as the central point in the network
Each switch determines the best path to the root bridge based on the lowest path cost
Ports on switches are designated as root ports, designated ports, or blocking ports to create a loop-free topology
Site-to-Site VPN on Palo Alto firewalls allows secure communication between different sites.
Configure VPN tunnel interface on both firewalls

A router is a networking device that forwards data packets between computer networks.
Routers operate at the network layer of the OSI model.
They use routing tables to determine the best path for data packets to travel.
Routers can connect different types of networks, such as LANs and WANs.
Examples of routers include Cisco, Juniper, and TP-Link.
Routers can provide security features such as firewalls and VPNs.
