DFD ( Data Flow Diagram) Working

 

Problem: Private traces can fail, but network gadgets may not detect it. This can result in statistics getting stuck because it can't be rerouted.

Reason: Traditional routing protocols rely on timers, which may be sluggish to come across disasters.

Solution: BFD protocol acts like a quick heartbeat test between routers. If one router would not respond fast sufficient, the issue is detected, and site visitors can be rerouted to the backup line.

Benefit: BFD allows avoid "facts forwarding black holes" by way of quickly switching to backup paths, improving community balance.

CONFIGURATION




Configured Loopback And Assign Ip Address on Router 1

R1(config)#inter lo 0

R1(config-if-Loopback 0) #ip add 1.1.1.1 32

 R1(config-if-Loopback 0) #inter g0/0

R1(config-if-GigabitEthernet 0/0)#ip add 12.0.0.1 30

Configured Loopback And Assign Ip Address on Router 2

 R2(config)#inter lo 0

R2(config-if-Loopback 0)#ip add 2.2.2.2 32

 R2(config-if-Loopback 0)#inter g0/0

 R2(config-if-GigabitEthernet 0/0)#ip add 12.0.0.2 30

 2. Complete OSPF basic configurations.

R1(config)#router ospf 1

 R1(config-router)#router-id 1.1.1.1

R1(config-router)#network 1.1.1.1 0.0.0.0 area 0

R1(config-router)#network 12.0.0.1 0.0.0.0 area 0

R2(config)#router ospf 1

 R2(config-router)#router-id 2.2.2.2

R2(config-router)#network 2.2.2.2 0.0.0.0 area 0

R2(config-router)#network 12.0.0.2 0.0.0.0 area 0

3. Complete interface BFD configuration and associate BFD with OSPF.

R1(config)#interface gigabitEthernet 0/0

R1(config-if-GigabitEthernet 0/0)#bfd interval 100 min_rx 100 multiplier 3

R1(config-if-GigabitEthernet 0/0)#ip ospf bfd

R2(config)#interface gigabitEthernet 0/0

R2(config-if-GigabitEthernet 0/0)#bfd interval 100 min_rx 100 multiplier 3

R2(config-if-GigabitEthernet 0/0)#ip ospf bfd

Q1. WHAT IS A ADDRESSING. Network addressing is like a two-part delivery system:   Logical Addressing (IP): This is like your permanent address (e.g., 192.168.1.1) that lets data find your device anywhere on the internet. Physical Addressing (MAC): Think of this as a unique ID for your device's network card (AA:BB:CC:DD:EE:FF) used for local delivery within your network. Q2. WHAT IS A PACKET AND FRAME . Packets: Layer: Network Layer (Layer 3) Content: The actual data you want to send, like an email, a video, or website information. Addressing: Contains logical addresses (IP addresses) to identify the sender and receiver on the network. Size: Can vary depending on the data type, but generally larger than frames. Travels across networks: Packets can travel across different networks, like the internet, as they are routed based on IP addresses. Frames: Layer: Data Link Layer (Layer 2) Content: The packet wrapped with additional information for local deliver...

DOS AND DDOS ATTACK

A Dos (Denial-Of-Service) Attack and A DDOS (Distributed Denial-Of-Service) Attack Are Both Attempts to Make a Computer System or Network Resource Unavailable to Legitimate Users. However, They Differ in How They Achieve This: Dos Attack: Imagine A Single Person Throwing Rocks at A Castle Gate. A This Person Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attacker Keeps Throwing Rocks, Trying to Overwhelm the Gate's Defenses and Gain Entry. Dos Attacks Are Typically Launched from A Single System. They Can Be Effective Against Small Systems or Networks, But Larger Systems Can Often Withstand Them. DDos Attack: Imagine An Army Throwing Rocks at A Castle Gate. This Army Represents the Attacker, And the Rocks Represent the Malicious Traffic. The Castle Gate Represents the Target System or Network Resource. The Attackers Coordinate Their Attack, Throwing Rocks from Multiple Directions at Once. ...

LSA TYPES

In OSPF, different types of routers create various types of LSAs (Link-State Advertisements) depending on their roles in the network. Here’s a breakdown of the routers and the LSAs they generate:   1. All Routers (including internal routers):    - Type 1: Router LSA       - Every router in an OSPF area generates a Type 1 LSA, which describes its own interfaces and links within the same area.   2. Designated Router (DR):    - Type 2: Network LSA       - The DR on multi-access networks (like Ethernet) generates this LSA to describe all the routers attached to the shared network.   3. Area Border Router (ABR):    - Type 3: Summary LSA       - ABRs generate Type 3 LSAs to advertise networks from one OSPF area to another (inter-area communication).    - Type 4: ASBR Summary LSA       - ABRs also generate Type 4 LSAs to describe the path to...
