How many types of routing protocols ?
- There are two types of routing protocols:
- Routing Information Protocols(RIP)
- Interior Gateway Protocol (IGRP)
- Open Shortest Path First (OSPF)
- Exterior Gateway Protocol (EGP)
- Enhanced interior gateway routing protocol (EIGRP)
- Border Gateway Protocol (BGP)
- Intermediate System-to-Intermediate System (IS-IS)
Routing Information Protocols(RIP)
- RIP protocol type used in local area network and wide area network.
- RIP (Routing Information Protocol) type is categorized interior gateway protocol within the use of distance vector algorithm.
Interior Gateway Protocol (IGRP)
- Interior gateway routing protocol created in part to defeat the confines of RIP (Routing Information Protocol) in large networks.
- It maintains multiple metrics for each route as well as reliability, MTU, delay load, and bandwidth.
Open Shortest Path First (OSPF)
- OSPF is an active routing protocol used in internet protocol.
- Mostly it is a link state routing protocol and includes into the group of interior gateway protocol.
- It operating inside a distinct autonomous system.
Exterior Gateway Protocol (EGP)
- Routing protocols is used to exchange routing information between different routers in different autonomous systems.
Enhanced interior gateway routing protocol (EIGRP)
- EIGRP supports IP subnets and improves the efficiency of the routing algorithms compared to older IGRP.
- It does not support routing hierarchies, like RIP.
Border Gateway Protocol (BGP)
- BGP connects the entire autonomous system/network path topology to other networks.
- It keeps routing table with topologies of all externally connected networks.
Intermediate System-to-Intermediate System (IS-IS)
- The Intermediate System to Intermediate System protocol functions similarly to OSPF.
- IS-IS is a great protocol used by network devices to determine the best method to promoted datagram from side to side a packet switched network and this process is called routing.
