A router is a networking device that forwards data packets between computer networks.
Routers operate at the network layer (Layer 3) of the OSI model.
They use routing tables to determine the best path for data packets to reach their destination.
Routers can connect multiple networks together, such as LANs and WANs.
They provide network address translation (NAT) to allow multiple devices to share a single public IP address...

BGP (Border Gateway Protocol) is a routing protocol used to exchange routing information between different networks on the internet.
BGP is used to connect different autonomous systems (AS) on the internet.
It is a path-vector protocol that selects the best path for data to travel based on various attributes such as AS path length, network delay, etc.
BGP is used by internet service providers (ISPs) to connect their netwo...
I was interviewed in Jun 2023.
Mac works on the Data Link layer.
Mac stands for Media Access Control.
It operates on the Data Link layer of the OSI model.
Responsible for the addressing of devices on a network.
Examples include Ethernet MAC addresses.
IP works on the network layer (Layer 3) of the OSI model.
IP stands for Internet Protocol.
It is responsible for routing packets across different networks.
IP addresses are unique identifiers assigned to devices on a network.
Examples of IP versions include IPv4 and IPv6.
EPON and GPON are types of passive optical networks used for delivering telecommunications services.
EPON stands for Ethernet Passive Optical Network and uses Ethernet technology for data transmission.
GPON stands for Gigabit Passive Optical Network and offers higher bandwidth and longer reach compared to EPON.
Both EPON and GPON are used for delivering high-speed internet, VoIP, and IPTV services to subscribers.
EPON is m...
ARP stands for Address Resolution Protocol, used to map IP addresses to MAC addresses. PON stands for Passive Optical Network, a type of fiber-optic network.
ARP is used to resolve IP addresses to MAC addresses on a local network
ARP operates at the data link layer of the OSI model
PON is a type of fiber-optic network that uses passive optical splitters to serve multiple users
Subnetting is the process of dividing a network into smaller subnetworks. Routers operate at the network layer (Layer 3) of the OSI model.
Subnetting involves creating multiple smaller networks from a single larger network by dividing the IP address range.
It helps in efficient utilization of IP addresses and improves network performance by reducing broadcast traffic.
Routers operate at the network layer (Layer 3) of the ...
Lan card works on the Data Link layer of the OSI model.
Lan card operates at Layer 2 of the OSI model, which is the Data Link layer.
It is responsible for the physical addressing of devices on the network.
Examples of Lan cards include Ethernet cards and wireless network adapters.

Ping and Traceroute are network diagnostic tools used to test connectivity and identify network issues.
Ping sends a small packet of data to a destination IP address and waits for a response. It measures the time it takes for the packet to travel to the destination and back.
Traceroute sends packets with increasing TTL values to the destination, and each router along the path sends back an ICMP message indicating its pre...
OSPF builds its database by exchanging LSAs with neighboring routers.
OSPF routers exchange Hello packets to establish adjacency.
Once adjacency is established, routers exchange Link State Advertisements (LSAs).
LSAs contain information about the router's interfaces, neighbors, and network topology.
Each router builds its own database based on the LSAs it receives.
The database is used to calculate the shortest path to each...
NSSA area is a type of OSPF area that allows external routes to be injected into the OSPF domain.
NSSA stands for Not-So-Stubby-Area.
It is used when an area needs to import external routes but still wants to maintain some level of stubbiness.
NSSA area has an ABR (Area Border Router) that translates Type 7 LSAs (Link State Advertisements) into Type 5 LSAs.
Type 7 LSAs are generated by ASBR (Autonomous System Boundary Rout...
No, RT and RD are required for MPLS VPN implementation.
RT (Route Target) and RD (Route Distinguisher) are used to uniquely identify VPN routes.
Without RT and RD, MPLS VPN cannot differentiate between different VPN routes.
RT and RD are used to import and export VPN routes between different VPNs.
RT and RD are also used for route filtering and traffic engineering.
Therefore, RT and RD are essential for MPLS VPN implementat
