Networking Chapter on Routing and Protocols

Routing

• R1 uses a network route to reach host 10.10.13.10/32
• Router 1 uses 10.10.13.208/29 for traffic to Host A, because this prefix is the longest match
• The longest prefix will be matched first in routing

File Transfer Protocols

• FTP is an application-layer protocol used for transferring files between hosts on a network.
• TFTP is a simplified version of FTP, often used on embedded devices.
• SCP encrypts data during transfer for more security than FTP.
• SFTP is a secure version of FTP, using SSH to secure the connection.

Switch Counters

• CRC Error: When a switch receives a frame with an error detected by the Frame Check Sequence (FCS), this counter is incremented.
• Input errors: This counter is incremented when the physical transmission has problems, and the received frame fails error detection.

Subnet Calculations

• Use the subnet mask (e.g., /18) to determine the network address and the usable host range.
• The subnet mask is represented in CIDR notation, where the number represents the number of bits used for the network portion of the address.
• In this context, '/18' is equivalent to 1100 0000 in binary.
• After determining the network address and usable host range, you can identify the subnet range.

Test your knowledge on key concepts in networking, including routing, various file transfer protocols, switch counters, and subnet calculations. This quiz covers essential topics that are crucial for understanding network communication and management.
