What is the full form of EIGRP?

Distance Vector Protocol

Enhanced Interior Gateway Routing Protocol (EIGRP) and Routing Information Protocol (RIP) frequently experience routing loops and mild convergence. EIGRP, a distance vector protocol created by Cisco, enables complex features including load balancing and route summarization.

By exchanging network information with adjacent switches, the Distance Vector Protocol is a particular type of guiding convention. The optimum next-hop router to use to connect to each destination network is listed in a table that is kept up to date by each switch. The table also includes the distance between each network.

The router will occasionally exchange routing updates with its neighbours. The network topology is conveyed by these upgrades. Despite their simplicity and ease of use, distance vector protocols like

Hybrid Routing Protocol

Link-state and distance vector routing technologies are combined in a hybrid routing paradigm. It combines the advantages of both types of protocols to provide a more workable and adaptable solution. An area-based routing protocol is used in each of the districts or regions that a hybrid routing protocol breaks up into on routers.

While data is transferred between routers using a distance vector protocol across areas, link-state protocol is utilised within an area. By minimising the size of the routing tables and controlling the spread of routing information, this increases the network's adaptability. Hybrid routing technologies include Open Shortest Path First (OSPF) and the Enhanced Interior Gateway Routing Protocol (EIGRP).

Classless Routing Protocol

Classless Routing Protocol is a sort of routing protocol that permits the utilize of variable length subnet masks (VLSM) and classless inter-domain routing (CIDR) to optimize IP address allotment.

Unlike classful routing protocols, classless routing protocols don't partition IP addresses into classes and permit for more efficient utilize of IP address space. Classless routing protocols also give way better scalability by permitting for more adaptability in network design and reducing the measure of routing tables.

Examples of classless routing protocols incorporate Border Gateway Protocol (BGP) and Open Shortest Path First (OSPF).

Cisco Proprietary Protocol

Cisco Proprietary Protocol refers to the routing protocols created by Cisco Systems and are utilized in their networking devices. These protocols are not standardized and can only be utilized with Cisco equipment. Some examples of Cisco exclusive conventions incorporate EIGRP (Enhanced Interior Gateway Routing Protocol), OSPF (Open Shortest Path First) for Cisco IOS, and Cisco's own VLAN Trunking Protocol (VTP). Whereas these protocols offer progressed features and capabilities, they are restricted to Cisco gadgets, and other vendors cannot execute them without a license or consent from Cisco.

Conclusion

In conclusion, the Enhanced Interior Gateway Routing Protocol (EIGRP) is a hybrid routing protocol that combines the features of distance vector and link-state protocols. EIGRP uses a composite metric that incorporates bandwidth, delay, reliability, load, and MTU to calculate the most excellent path to a destination network. It is a classless protocol and supports variable length subnet masks (VLSMs).

EIGRP is a Cisco proprietary protocol and is broadly utilized in enterprise networks. Its fast convergence, scalability, and support for multiple organize layer protocols make it a well-known choice for network administrators.

FAQs

Q1. What is EIGRP's administrative distance?

Ans: EIGRP's administrative distance is 90 by default, making it more dependable and popular than competing routing protocols that have a larger administrative distance.

Q2. Does EIGRP offer VLSM and CIDR support?

Ans: Yes, EIGRP supports both Classless Inter-Domain Routing (CIDR) and Variable Length Subnet Masking (VLSM). EIGRP can handle networks with various subnet masks and route IP packets more effectively as a result.

Q3. Are IPv6 networks compatible with EIGRP?

Ans: It has been modified to handle IPv6 networks, making EIGRP a good routing system for both IPv4 and IPv6 contexts.
