OSPF stands for Open Shortest Path First. It is a open standard (allows multi-vendor deployment), link state, dynamic routing protocol. Uses Dijkstra algorithm Algorithm. They send the updated routing information to all other routers on the network whenever there is a change in the network. It creates three separate tables – neighbor table, topology [...]
EIGRP stands for Enhanced Interior Gateway Routing Protocol. It is a CISCO proprietary (only can be used on CISCO devices), hybrid, dynamic routing protocol. Uses Diffusing Update Algorithm (DUAL). They send the updated routing information to all directly connected neighbors whenever there is a change in the network. It creates three separate tables – [...]
