IP Routing Concepts Review
What are Interior Gateway Protocols (IGPs)?
Interior Gateway Protocol (IGPs) are a type of protocol that is used for transmitting routing information within autonomous systems (AS) using TCP/IP protocol. Unlike Exterior Gateway Protocols (EGPs) like BGP, which exchange routing information between routers in different AS, IGPs exchange routing information between routers within the same AS.
An example of an IGP is Routing Information Protocol (RIP), which is a distance-vector routing protocol. In this protocol, routers don't have knowledge about the full network topology. Instead, each router advertises the distances to other routers that they know until the routing table is populated.
Open Shortest Path (OSPF) is another example of an IGP. It is a link-state routing protocol, in which every router knows the full network topology and independently calculates the best path between them.
Enhanced Interior Gateway Routing Protocol (EIGRP) is an example of an IGP that uses the features of both distance-vector routing protocols and link-state routing protocols.
