OFC stands for Optical Fiber Cable, which is a type of cable made of glass or plastic fibers that transmit data using light.

• OFC is used for high-speed data transmission over long distances.

• It is commonly used in telecommunications, internet, and cable TV networks.

• OFC is more reliable and has higher bandwidth than traditional copper cables.

• Examples of OFC include single-mode fiber and multi-mode fiber.

• OFC requires speci...read more

Multiplexer is a device that combines multiple signals into one signal. Demultiplexer is a device that separates one signal into multiple signals.

• Multiplexer is also known as MUX.

• It is used to increase the capacity of a communication channel.

• Demultiplexer is also known as DEMUX.

• It is used to route a single input signal to multiple output signals.

• Multiplexer and demultiplexer are commonly used in digital communication s...read more

OTDR stands for Optical Time Domain Reflectometer. It is a device used to test and troubleshoot fiber optic networks.

• OTDR sends a pulse of light into the fiber and measures the time and strength of the reflected signal.

• It can detect faults such as breaks, bends, and splices in the fiber.

• OTDR can also measure the length of the fiber and the attenuation of the signal.

• It is an essential tool for maintaining and repairing ...read more

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...read more

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...read more

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...read more

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
