Routing protocols are predetermined sets of guidelines that routers employ to send and receive data. They merely update the routing table that has the information, not moving it from a source to a destination. If you want to know What are Routing Protocols in CCNA? You can join the CCNA Course in Chennai at FITA Academy.
Network router protocols aid in defining the channels of communication between routers. The computer enables the network to choose a path between any two network nodes.
Static Routing Protocols
Standard routing protocols are applied when the administrator chooses the route manually from the source to the destination node. As a result, the network is given additional security.
Advantages
- No CPU load on the router.
- No dead space between links.
- Route addition is only possible by the administrator.
Dynamic Routing Protocols
Another crucial category of routing protocols is dynamic routing protocols. It makes it possible for routers to update their routing tables with data from linked routers automatically. These protocols communicate topology updates when the network’s topological structure changes.
Advantage
- Even on larger networks, a configuration is simplified.
- It will be able to choose a different path dynamically if a link fails.
- It aids in load balancing across multiple links.
Distance Vector Routing Protocol (DVR)
Many bandwidths are consumed by distance vector protocols to promote their routing table to each connected directly neighbour at regular time intervals and congregate slowly.
When a route has become unavailable in a distance-vector, all routing tables should be updated with new data. Are you looking for CCNA Course? FITA Academy is the best institution with the experts to teach CCNA Course Online and also offers Placement Assistance.
Advantages:
- Network updates are exchanged regularly, and they are always broadcast.
- This protocol always trusts route on routing information received from neighbour routers.
Internet Routing Protocols:
Protocols that help data packets find their way across the Web includes the following:
Routing Information Protocol (RIP)
In LAN and WAN networks, RIP is used. It also works at the OSI model’s application layer. RIP stands for Routing Information Protocol.
- RIPv1
- RIPv2
The original version, known as RIPv1, aids in the determination of network links based on IP location and hop count travel. RIPv1 conveys with a system by transmitting its IP table to all network routers.
Interior Gateway Protocol (IGP)
IGRP is a subtype of the CISCO Distance Vector Internal Gateway Protocol. It was created to overcome the limitations of RIP. Load, bandwidth, latency, MTU, and durability are the metrics used. Routers are widely used within autonomous systems to exchange routing data.
This routing protocol transmits every second and is best suited for large networks with a maximum hop number of 255. When compared to RIP, it aids in the management of large networks.
Because it is updated automatically when route changes take place in a specific network, IGRP is broadly used because it ensures the routing loop. The option to load balance is also available traffic on equivalent metric cost paths.
Link State Routing Protocol
Link state protocols employ a novel approach to determining the best routing path. The route determined in this protocol depends on the speed of the path and the charge of resources. Join CCNA Course In Bangalore and learn professionally with certification from industry leaders.
