EIGRP important Questions for interview

What is EIGRP? Enhanced Interior Gateway Routing Protocol (EIGRP) is an enhanced distance vector routing protocol which uses Diffused Update Algorithm (DUAL) to calculate the shortest path. It is also considered as a Hybrid Routing Protocol because it has characteristics of both Distance Vector and Link State Routing Protocols.EIGRP supports classless routing and VLSM, route summarization, incremental updates, load balancing, and other features. What are the requirements for neighborship in EIGRP? The following fields in a hello packet must match for routers to become neighbors:- 1. Autonomous System number. 2. K-values. 3. Authentication. 4. The primary address should be used. 5. If static neighborship then should be defined on both sides. What is the metric of the EIGRP protocol & its default values? 1. Bandwidth (K1=1) 2. Load (K2=0) 3. Delay (K3=1) 4. Reliability (K4=0) 5. Maximum Transmission Unit (K5=0) By default, EIGRP only uses Bandwidth (K1) and Delay

OSPF Important Interview Questions and Answers

What is the OSPF Routing Protocol? Open shortest path first is an Open Standard Link State routing protocol which works by using the Dijkstra algorithm to initially construct the shortest paths and follows that by populating the routing table with resulting best paths. What are the steps required to change neighborship into adjacency? 1. Two-way communication (using Hello Protocol). 2. Database Synchronization which means exchange of Database Description (DD) packets, Link State Request (LSR) packets, Link State Update (LSU) packets. After Database synchronization is complete, the two routers are considered adjacent. Explain LSA (Link-State Advertisement), LSU (Link State Update) and LSR (Link State Request)? The LSAs (Link-State Advertisements) are used by OSPF routers to exchange routing and topology information. When two neighbors decide to exchange routes, they send each other a list of all LSAs in their respective topology database. Each router then checks its topolog
