Classful and Classless Routing Protocols

Classful Routing Protocol: Transmits no subnet mask information; recognizes Class A, B, and C boundaries and performs autosummarization. Does not support Variable Length Subnet Masking (VLSM).
Routing: The process of moving data packets through a network to their destination.
Router: A device that directs traffic on a network, acting as a facilitator for data packet movement.
Protocol: Established rules for communication between devices on a network.
Classless Routing Protocol: Sends subnet mask and supports VLSM. Examples include RIPv2, EIGRP, OSPF, and IS-IS.
Routing Algorithms: Software employed by routers to determine optimal paths for data packets.
Distance Vector: A category of routing protocol that shares full routing table copies with directly connected neighbors.
RIPv2 (Routing Information Protocol version 2): A classless, distance vector protocol that includes subnet masks in routing updates and supports CIDR supernets and discontiguous networks.
VLSM (Variable Length Subnet Mask): Allows different sized subnets to exist within the same network address space.
EIGRP (Enhanced Interior Gateway Routing Protocol): A classless, advanced distance vector protocol for automation of routing decisions. Cisco proprietary, used exclusively on Cisco routers.
OSPF (Open Shortest Path First): A classless link-state routing protocol that dynamically monitors network changes through router link state advertisements.
IS-IS (Intermediate System to Intermediate System): A classless link-state protocol known for fast convergence and scalability, efficiently using network bandwidth.
Discontiguous Network: An internetwork design where packets between subnets of the same classful network are routed through another classful network.
RIPv1 (Routing Information Protocol version 1): A classful protocol, lacks a subnet mask field, operates on broadcast method for sharing routes.
IGRP (Interior Gateway Routing Protocol): A classful distance vector protocol developed by Cisco, an improvement over RIP and RIPv2, without a mask field.
Link-State Routing Protocol: Enables routers to share routing information beyond neighbors, allowing for independent network mapping and path determination.
BGP (Border Gateway Protocol): A classless path-vector routing protocol that serves as the primary exterior gateway protocol of the Internet, considering multiple factors in routing decisions.
Supernetting: Technique that allows multiple networks to be represented by a single subnet mask, streamlining routing.
