EIGRP (Enhanced Interior Gateway Routing Protocol) is an improved version of the original IGRP protocol developed by Cisco Systems. Cisco-specific EIGRP routing technology combines the advantages and benefits of link-state protocols and distance vector protocols. EIGRP maintains the same distance vector algorithm and original IGRP matrix information; however, considerations regarding convergence time and expansion capacity … →

OSPF (Open Shortest Path First) is an internal gateway hierarchical routing protocol or IGP (Internal Gateway Protocol) that uses the Dijkstra link-state algorithm (LSA – Link State Algorithm) to calculate the route. It uses “cost” as a metric measurement as possible and additionally creates the same link-state database for all routers in the zone. OSPF … →

RIP (Routing Information Protocol) is the first protocol developed and used to meet the increasing demands of complex networks over time. It is still popular because of its simplicity and broad compatibility. It is an internal gateway protocol or IGP (Internal Gateway Protocol) used by routers, derived from the XEROX GWINFO protocol and becoming the … →

VLAN (Virtual Local Area Network) is an essential factor in the efficiency of an organization. It is one of the technologies that contribute to improving network performance and allows the dividing of large broadcast domains into smaller domains. In network topology, routers block broadcast traffic on an interface. However, routers usually have a limited number … →
